Jumping The Electrification Gap Between Leeds And Manchester

The Battery High Speed Train

An Aventra uses a modern version of the same bogies that are used in the Class 222 trains, which are capable of 200 kph. As the Class 387 train, which is a version of the Electrostar, can travel at 110 mph, I wouldn’t rule out that the more modern Aventra could run at 200 kph or 125 mph. Obviously, this speed would probably only be attainable in places on the East Coast Main Line.

Example times between York and Newcastle include.

  • East Coast InterCity 225 – 56 minutes
  • East Coast InterCity 125 – 62 minutes
  • Transpennine Class 185 – 67 minutes

So if the performance on the line of an Aventra IPEMU was the same as an InterCity 225, then this would knock eleven minutes of the trip to Newcastle

Acceleration on batteries would be the problem, not maintaining a high speed. that had been built up whilst running under the wires.

When jumping the gap in the electrification between Leeds and Manchester, as the train will have been running from either Liverpool or York, I would suspect that it would set out over the Pennines with a full load of electricity.

 

Manchester To Leeds Electrification Gap

The Manchester to Leeds electrification has now been paused and it is likely that it will not be completed in the next ten years.

The line has its problems as the three-car Class 185 trains, that work the line, are totally inadequate for the route.

There are two major routes between Leeds and Manchester.

The shortest distance by rail between Manchester and Leeds is just 43 miles. When I saw this, I didn’t believe it, but it’s all in this article in the Guardian.

So this means that if you want to run an electric train between Liverpool and Manchester to Leeds, York and Newcastle, the Aventra IPEMU would bridge the gap with ease.

The demonstration version of the Aventra IPEMU was a modified Class 379 Train and had a range of sixty miles on batteries.

So even this modified Stansted Express would have been able to bridge the gap on both routes with ease.

A fully engineered production Aventra IPEMU would be unlikely to have a shorter range on batteries.

So Aventra IPEMUs create a fully-electrified TransPennine route from Preston, Liverpool and Manchester in the West to Leeds, York and Newcsastle in the East.

Destinations In The West

These are all current Western destinations for Transpennine Express.

  • Barrow – On an unelectrified branch line from an electrified Carnforth.
  • Blackpool North – On an unelectrified branch line from an electrified Preston.
  • Liverpool – On a direct line from Manchester that is completely electrified
  • Liverpool via Warrington  – On a direct line from Manchester that is partially electrified.
  • Manchester Airport – Electrified from Manchester
  • Windermere – On an unelectrified branch line from an electrified Oxenholme.

All could be served by using Aventra IPEMUs.

I suspect it would also be possible to serve Chester.

I’m not sure how Aventra IPEMUs would affect slower services like York to Blackpool North across the Pennines, but I suspect they would be faster than the current diesel multiple units.

With the franchises being reallocated, I suspect that it will be done in such a way, that the trains across the Pennines give a much better service.

Destinations In The East

These are all current Eastern destinations for Transpennine Express.

Cleethorpes – Probably too far, but the Class 185 trains could run the service as they do now!

Hull – Hull is perhaps fifty miles East of the East Coast Main Line and I believe that a solution can be found to do this on an out-and-back basis.

Middlesbrough – This is a few miles from Darlington

Newcastle – Electrified all the way from Leeds

Scarborough – The York to Scarborough Line is forty two miles long and I believe that a solution can be found to do this on an out-and-back basis.

Whether Aventra IPEMUs can do the return trip from the East Coast Main Line on an out-and-back basis to Hull and Scarborough, depends very much on how the range of the trains work out, when the production trains are delivered. I suspect Bombardier know and have either calculated it or proven it on a test rig, but obviously they are keeping it quiet and sticking with the sixty miles total range obtained with the Demonstrator.

If they can’t make it, I suspect that they can provide some form of charging at the Eastern termini.

I do suspect that because of the reorganisation of the two franchises we may see some extra destinations in the East.

Times Across The Pennines

At present times on the major routes are.

Liverpool to Newcastle – 3 hours

Liverpool to Hull – 2 hours 30 minutes with a change at Leeds

As I indicated earlier there is eleven minutes to take off the Newcastle journey and the change at Leeds probably wastes ten minutes on the Hull trip.

Other factors would have an effect.

  • The time spent on a stop by the Aventra IPEMU will be less than that of the current Class 185 trains.
  • If diesel multiple units on the two TransPennine routes can also be replaced with Aventra IPEMUs, then these trains would be less likely to slow the fastest expresses.
  • The Aventra IPEMUs are faster than the current trains.
  • Network Rail will probably be able to do some small amount of trackwork to speed trains up in places.

I have no idea what the eventual TransPennine time will be, but it will be a few minutes less than today’s times.

Is Coal In Terminal Decline?

I’m no lover of coal, because of all the pollution and carbon dioxide it creates. I’ve also never met anyone from a coal mining family, who would ever want to work in a mine.

So when I look at the latest freight statistics from the Office of Rial and Road, I am rather pleased to see that in the last year coal traffic on UK railways has fallen over the last twelve months, from 1.66 billion net tonne km to 0.64 billion net tonne km (a drop of 61.2%).

As this is mainly imported coal to be burned in coal-fired power stations, I don’t think it is bad for employment. Power stations may be closing, but new ones must be opening to fill the gap in electricity generation.

An Open Letter To George Osborne About Teeside

I should say, I have no connection to Teeside, except that I quite like the area.

There is little that can be done about SSI Redcar, other than hope for a miracle, as there is so much steel being produced in the world, that the price will only get lower and the plant will get less and less economic.

I also live in Dalston, which since the arrival of the London Overground five years ago, has very much gone up in the world! And in some ways, like employment, gone up for those at all levels in society.

So I very much feel, that improving a railway and other forms of public transport, can only make an area more attractive for investment, employment, living and leisure.

Teeside has been lobbying for a Metro for years, to link the knit the area together.

There is only one way that this can be provided in the absolutely necesary short time-scale.

The railway line between Newton Aycliffe and Middlebrough should be electrified, as soon as possible. Immediately, this would enable.

  • The new trains being produced at Newton Aycliffe by Hitachi, to get to the East Coast Main Line under their own power.
  • Direct electric train services between Middlesbrough, Darlington and all points North and South from Edinburgh to London on the East Coast Main Line.

Northern Rail or their successor have been mandated in the new Invitation to Tender for the franchise to provide 120 new carriages to replace the disgusting Pacer trains.

Some of these new carriages should be the IPEMU variant of the new Aventra trains, being produced by Bombardier at Derby, which could by the use of the electrification at Middlesbrough and on the East Coast Main Line and the trains on-board batteries be able to run on the following routes.

  • Saltburn to Bishop Auckland via Middlesbrough and the Tees Valley Line
  • Hexham to Nunthorpe via the Tyne Valley Line, Newcastle, Sunderland, the Durham Coast Line, Hartlepool and Middlesbrough.
  • Middlesbrough to Whitby could be done later.

The faster electric trains would increase capacity, decrease journey times and improve frequencies.

The only construction needed for the new trains, would be a small amount of platform lengthening and adjustments to the track and signalling.

Other Train, Tram And Tram-Train Manufacturers And IPEMUs

The Aventra IPEMU is a Bombardier product, but I can’t see anything about using batteries in a train being patentable.

In the future we will see a range of energy storage devices based on all sorts of technology for transport applications. Kinetic Energy Recovery Systems describes the technology in Wikipedia

To deliver energy saving in transport, they need to be installed with regenerative braking and some clever control systems.

They are best generally described as kinetic energy recovery systems or KERS.

Applications will include.

  • Passenger Cars  – A sexy image would sell top-of-the-range hybrid and electric cars.
  • Buses – Hybrid and electric buses in cities are the way forward and they’ll need intelligent energy storage.
  • Trucks, Vans and other Commercial Vehicles – Why not, if it makes them more attractive to operators and makes vehicles more environmentally friendly?
  • Trams, Trains and Tram-Trains – The Aventra IPEMU is just the first.

Looking at KERS in motor sport and Formula One in particular, in Wikipedia, there are several ideas, some of which are based on batteries and others on mechanical systems like flywheels.

As buses, trams, trains and tram-trains tend to be large vehicles with plenty of available space, where quite a large KERS can be tucked away, it is probably not the demanding weight-sensitive application of say motor sport or passenger cars.

So I don’t see any reason why a train or bus manufacturer like Alstom, Hitachi, Siemens or Wrightbus will not fit KERS.

Wrightbus are mentioned in this press release from Torotrak entitled FUEL SAVING KINETIC RECOVERY SYSTEM PROJECT READY FOR NEXT PHASE. This is the first paragraph.

Wrightbus have confirmed that an innovative Kinetic Recovery System (KERS) project, developed in a collaborative partnership and partially funded by Innovate UK, the UK’s innovation agency, is in full service trials with project partner Arriva.

Overall, this project looks very like the partnership that created the IPEMU demonstrator to prove the technology for trains, as it involves a bus manufacturer, a couple of technology or engineering companies, a transport operator and funding from the Government.

Incidentally, Torotrak is a British company with links to BAe Systems.

According to the press release the prototype bus is in service in Gillingham in Kent.

I can’t believe that the other train manufacturers are not looking seriously at KERS.

It is interesting to look at this article from Bus and Coach, which describes the Wrightbus project.

It is complicated mechanical setup, compared to installing KERS in an all-electric tram, train or tram-train, where it is a matter of designing an intelligent control system to link.

  • Overhead electric supply at 25 kVAC or 750 VDC
  • Third rail supply at 750 VDC
  • Traction motors
  • KERS
  • On-board electrical systems like air-con, lights and passenger displays

The control system would balance the sources and needs according to route and load.

I think that any train manufacturer that doesn’t offer KERS  as standard on a train or tram will be an also-ran!

The Technology That Enables The Aventra IPEMU

It is worth stating why it looks like the Aventra IPEMU looks so promising.

Steel Wheel On Steel Rail

The dynamics of this are well known and mean the following.

  • There is a very low rolling resistance.
  • As more weight is applied, the rolling resistance goes down.
  • A fully loaded train might use less energy than an empty one.

You can’t ignore the laws of physics.

Aerodynamics

The air resistance of something like a train rises with the square of the speed.

But by careful aerodynamic design, you can reduce this energy loss substantially.

An Artist's Impression Of A Proposed Aventra

An Artist’s Impression Of A Proposed Aventra

The picture shows the clean lines of an Aventa

FLEXX-Eco Bogies

Boring but the design saves energy.

Low Energy Interiors

Air-conditioning and door and lighting systems have made great strides in recent years on reducing energy consumption.

Improved Energy Storage

The Class 379 Demonstrator used batteries, as nothing else was available. Better technology for this application like large capacitors and flywheels may be better suited to a train.

Because of the steel wheel on steel rail advantage weight is not a problem.

I think in a few years time, trains will use KERS. Like Formula 1, only bigger! It will be more affordable than batteries, as it’s purely electro-mechanical!

Regenerative Braking

Regenerative braking can save large amounts of energy, with Class 390 Pendolinos reportedly saving seventeen percent. But these trains give their generated energy to the overhead lines, whereas an Aventra IPEMU will keep the energy for itself in the storage device, if there is capacity.

From an electrical engineering point of view, I do wonder if energy storage is the best way to handle the electricity generated by regenerative braking, as otherwise it might have to be converted to transmit it back into the overhead wire or third rail.

I can see a time coming, when all electric trains have regenerative braking and energy storage!

Lightweight Construction

This only helps in the acceleration of the train, so it may not be as important as it would seem, because of the steel wheel on steel rail advantage.

Could it be that one of the reasons a High Speed Train rides so well, is that it is built out of steel and is strong and heavy?

Automated Systems

Things like pantograph deployment will be automatic, thus meaning when the train needs to add power and there is an overhead wire, this will be connected to power the train or top up the battery.

Automatic Train Control

But the biggest automation will be in the driving of the train. As on the Victoria Line the driver will tell the train to start and then it will go automatically to the next station. The train will collect information from the timetable, signals, GPS and sensors determining things like weather and passenger load and be driven accordingly.

Planes have been flown like this for many years.

Conclusion

The range of sixty miles quoted for the Demonstrator could be exceeded by a wide margin.

Thoughts On Midland Main Line Electrification

I have been thinking about how the method of electrifying the Midland Main Line might change if the Aventra IPEMU was available.

These are thoughts in no particular order.

The Battery High Speed Train

An Aventra uses a modern version of the same bogies that are used in the Class 222 trains, which are capable of 200 kph. As the Class 387 train, which is a version of the Electrostar, can travel at 110 mph, I wouldn’t rule out that the more modern Aventra could run at 200 kph or 125 mph.

Acceleration on batteries would be the problem, not maintaining a high speed. that had been built up whilst running under the wires.

Also, when the train comes to the end of its northward journey at say Corby, it has to brake. With regenerative braking on the Aventra IPEMU, all of this energy would go back into the batteries.

So does this mean that no charging would need to be provided at say Corby?

I’m not totally sure of the mathematics and physics, but I’m certain that a battery electric train with regenerative braking, would put a significant part of the electricity it would need to accelerate away from a station, into the batteries as it stopped.

This would mean that stops at Wellingborough and Kettering would not stop Corby services from reaching their destination.

St. Pancras to Corby

I estimate that the distance from the end of the electrification at Bedford and Corby station is about thirty five miles.

This would mean that this route out of St.Pancras could be covered by an Aventra IPEMU.

Would this release a Class 222 train for use elsewhere? Or would the Aventra IPEMUs enable East Midlands Trains to offer more capacity or an increased frequency on this service?

St. Pancras to Leicester

I estimate that the distance from the end of the electrification at Bedford and Leicester station is about fifty miles.

This would mean that this route out of St.Pancras to Leicester could be covered by an Aventra IPEMU, especially if it were possible to recharge the train at Leicester, using the sort of short electrification, I wrote about at Rugeley Trent Valley station in Up And Down The Chase Line.

Leicester has problems as a station, as this extract from Wikipedia says.

Train operators using the station include CrossCountry and East Midlands Trains. Due to a 15 mph maximum speed to the south of the station, all passenger trains stop at the station. Up until the winter 2008 timetable, the morning southbound The Master Cutler express from Leeds to London St Pancras was an exception although this now also calls.

Leicester is a bottleneck station as it has only four platforms. All platforms are well utilised, especially platforms two and three which receive freight as well as passenger trains. A freight loop goes to the east of the station alongside the carriage sidings which run adjacent to platform four.

This Google Map of the station shows the platforms and the freight loop.

Leicester Station

Leicester Station

It does look that there would be space to expand the station and from this section in Wikipedia, I’m sure Network Rail are working on an upgrade to the area to address all the problems.

It would appear to be stating the obvious to say, that Leicester station must be sorted first before any electrification in the area.

An extra bay platform would probably allow Aventra IPEMUs to run an electrified service to St. Pancras, if East Midlands Trains felt this was needed. Because of the regenerating braking of the train, it might not be necessary to provide a means of charging the trains at Leicester.

Creating A High Speed Route To Chesterfield and Sheffield

A few years ago, much of the Erewash Valley Line was upgraded ready for electrification and high speed running. On the Future of this line, Wikipedia says this.

Network Rail as part of a £250 million investment in the regions railways has proposed improvements to the junctions at each end, resignalling throughout, and a new East Midlands Control Centre.

As well as renewing the signalling, three junctions at Trowell, Ironville and Codnor Park will be redesigned and rebuilt. Since the existing Midland Main Line from Derby through the Derwent Valley has a number of tunnels and cuttings which are listed buildings and it is a World Heritage Area, it seems that the Erewash line is ripe for expansion. As the new signalling is rolled out, train detection is moving away from the traditional Track circuit detection of trains to Axle counting.

So could we see all of the very fastest services from St. Pancras to Chesterfield and Sheffield using this route?

Is the route from Trent Junction in the South to Chesterfield and Sheffield in the North ready for electrification?

Network Rail must ensure that as much of the line is capable of 125 mph running and that all bridges and tunnels have sufficient clearance from London to Sheffield via Chesterfield.

Creeping The Electrification North

From Bedford the electrification would be crept north at a sensible pace, which would be designed to cause minimum disruption to services.

Every mile it went north would increase the reach of the new electric trains, but only after the bottleneck of Leicester was eased to allow high speed running through the station.

The Electric Spine

If the Electric Spine was to be implemented in full from Southampton to Sheffield and Doncaster, then the electrification must be completed North of Bedford.

But as there are a lot of places where the electrification will not be completed elsewhere, will we see a shift towards electro-diesel freight locomotives like the Class 88.

So although freight would take advantage of an electrified Midland Main Line, it may not be as important as many think.

Completing The Electrified Routes to Sheffield, Nottingham and Derby

These three important cities all have extensive local rail networks, that could benefit from an electrified hub, so that Aventra IPEMUs could be used to bring benefits to all the communities served by diesel multiple units and in Sheffield’s case, quite a few Pacers.

So as a minimum, this electrification must be completed.

  • East Midlands Parkway to Derby
  • East Midlands Parkway to Nottingham
  • East Midlands Parkway to Chesterfield and Sheffield via the Erewash Valley Line.

Chesterfield to Derby would probably be filed in the Too Difficult box, but would be an easy run for an Aventra IPEMU.

Note that I would start the electrification from East Midlands Parkway, as this station and the Airport are talked about as destinations for tram-train services.

Obviously to complete the Electric Spine, the following electrification would also need to be done.

  • Complete the electrification between Bedford and East Midlands Parkway.
  • Sheffield to Doncaster.

But once Sheffield station is electrified none of the many local lines reaching out from the city would need to be electrified, as most services could be run using Aventra IPEMUs. Obviously, if there was a special reason like freight or tram-trains, this wiring would only help the Aventra IPEMUs.

New Elecric Services

Once electrification has been installed up the Erewash Valley Line to Sheffield, lots of important places become within range of Aventra IPEMUs running from St. Pancras.

  • Barnsley
  • Bradford
  • Huddersfield
  • Leeds
  • Manchester

It would also mean that several existing cross-country services could be run using electric trains.

  • Liverpool to Norwich
  • Nottingham to Cardiff
  • Bristol to Newcastle

Remarkable in some ways as a lot of electrification has been dropped.

Thoughts On Electrification

This document is for your eyes only and is to brief you for Monday.

By chance, a few days ago, I happened to go to Manchester with two guys from one of the big insurance companies, who are in to financing infrastructure like housing, office complexes, ports and shopping centres.

Their thoughts led me to this way of thinking.

The Problems Of Electrification

We all know of the problems of electrification and the related one of too few independent powered multiple units.

A few things I have seen and thought.

  • Northern Rail has cut back the service between Liverpool and Blackpool to Preston, except for a couple of services. Have they given up temporarily on Blackpool ever getting electrified?
  • I feel that electrification is suffering from a lack of resources.
  • Electrification in the North West is suffering terrible ground problems.
  • The October edition of Modern Railways is saying that there is uncertainty over the start date for the Gospel Oak to Barking electrification.
  • If I was looking for conspiracy theories, all references to Midland Main Line electrification has been removed from Wikipedia.
  • When a few weeks ago I visited all work between Preston and Blackpool had ceased and they’d tidied it all up. But bridges and platforms looked like they were ready for new four-car electric trains. I wrote What’s Gone Wrong With The Blackpool To Preston Electrification?
  • Then today, I went to look at the electrification on the Chase Line and wrote Up And Down The Chase Line.

In both the Blackpool and Chase Lines electrification, they would have appeared to have rebuilt the bridges and lengthened the platforms, but had then tidied up and gone away. There were no piles of uninstalled steelwork for the overhead lines, you see up and down the GWR.

Electrification is said to be paused. These looked very much like long ones to have a serious think about it.

But both lines would accept a four-car diesel multiple unit immediately.

The Aventra IPEMU

Help is at hand in the shape of the new Aventra IPEMU train. ( IPEMU stands for Independently Powered Electric Multiple Unit)

An Artist's Impression Of The Proposed Aventra

An Artist’s Impression Of The Proposed Aventra

These are facts about the Aventra and its IPEMU variant.

  • The Aventra should be a modern train, to as high a standard as any train anywhere.
  • Aventras will start to be delivered by the end of 2017.
  • All the train and manufacturing technology has been proven for years or is running in the latest Electrostars.
  • There has not been one adverse comment on the Class 379 IPEMU Demonstrator, that I can find.
  • The Class 379 IPEMU Demonstrator was financed by Abellio Greater Anglia, Bombardier and Network Rail.
  • I rode the test train and the on-board engineer told me the performance on battery was the same as an unmodified train and that it had a range of up to 60 miles without overhead power.
  • Bombardier have sent me documents that say that all Aventra trains will have the capacity to run as IPEMUs by the addition of an appropriate energy storage device like a battery or supercapacitor.
  • Aventras can be introduced on to any line that can handle a modern four car diesel multiple unit, where there is enough electrification at one or both ends.
  • Aventras can be changed from standard to IPEMU variant to fit the numbers required for schedules.
  • I do wonder if all Aventras would have an IPEMU capability, as this must make operation easier for train companies. If all trains had energy storage, would depots be wire-free for a start?
  • There will certainly be 110 mph Aventras, but will they go even faster to say 125 mph?
  • Aventras have regenerative braking and may be lighter than Electrostars.
  • An engineer who worked on the InterCity 125 said to me, that aerodynamic drag on trains is one of the biggest problems. It also goes up with the square of the speed. An Aventra with its smooth front end will need less power than a corresponding Electrostar.
  • There is also a paradox with rolling resistance of steel wheels on steel rails. The more heavily-loaded a train, the less the rolling resistance!

Various rumours are circulating that train operating companies are considering ordering IPEMUs.

  • GWR were mentioned in the September Modern Railways.
  • Merseyrail were mentioned in the October Modern Railways.

So the concept must have impressed people with cheque-books.

With my electrical engineering hat on, I would add.

  • BAe Systems, GKN and others are experimenting with flywheels as energy storage devices for buses and other large road vehicles and specialist applications like KERS in Formula One. I suspect that the technology will end up in trains. Modern Railways is also talking this month about KERS for the Class 230.
  • Retrofiting new and improved energy storage systems will be a very simple operation.
  • Switching from overhead line or third rail power to battery could be totally automatic and controlled by GPS and ERTMS.
  • Some routes like York-Scarborough, may be a bit long for the Aventra IPEMU, as although the train could easily do one-way on batteries, going out and back would not be possible.  Some form of charging system, whilst in the terminal platform must be possible. A modern third-rail system in stations? Or a short length of overhead wiring as has been installed at Rugeley Trent Valley.
  • Say an Aventra IPEMU was going at 100 mph towards a terminal station, as trains do on many unelectrified lines in the UK. How much energy would be put into the battery by regenerative braking as the train stopped in the station. So calculations of an out-and-back range are complicated and could be much longer than expeced.
  • Smart driving systems linked to GPS, ERTMS and people counting and weight calculating software will improve range. As a control engineer, I would never underestimate how far the perfect automatic driver might take a train on a full charge on a predictable route.

Overall, I think that the range of an Aventra IPEMU on batteries will grow! At present all published range figures are based on  a cobbled-together prototype, based on an Electrostar built using ten-year old technology. Bombardier have probably created a computer simulation of a definitive Aventra IPEMU, with fully integrated systems running over known routes, which would give true figures.

When the final figure is announced prepare to be surprised!

Where Could An Aventra IPEMU Be Used?

Basically anywhere, where one or both ends of the line are electrified. How about?

  • Gospel Oak to Barking – There is enough electrification at the Barking end, especially if the extension to Barking Riverside was built first. It would immediately release eight Class 172s.
  • Manchester to Leeds by all routes including Huddersfield and Caldervale. – It’s well under 60 miles and could give Liverpool to Newcastle in under two and a half hours without any more expensive electrification.
  • Cardiff Valleys Lines – Electrification has been costed at £350million. At £8million or so for an Aventra IPEMU, it must be cheaper to cut back on the electrification and buy some new trains. No more London cast-offs!
  • Hexham to Middlesbrough – It would need some electrification at Middlesbrough.
  • Bristol and Teesside Metros and expansion and modernisation of local train services in Birmingham, Edinburgh, Glasgow, Liverpool, Leeds and Newcastle.
  • Edinburgh to Tweedbank
  • St. Pancras to Hastings and Eastbourne via Ashford.
  • Salisbury to Exeter – Probably too long now, but once the technology is proven and a small amount of electrification was put in at Exeter and Salisbury, I think this line will go electric.
  • St.Pancras to Corby and Leicester. – This is probably possible and could lead to an interesting philosophy for electrifying the Midland Main Line.

Many routes would need little or no modification, other than to allow four-car trains and adjustments to track and signalling, most of which could be done without too much inconvenience to passengers and train companies.

I am going to see what proportion of the country can be served by Aventra IPEMUs. I suspect, it’s upward of more than fifty percent.

The places that can’t be served are not very many.

  • The South-West
  • Chiltern
  • North Wales
  • North of Scotland
  • Cumbria
  • Lincolnshire
  • Around Derby, Nottingham and Sheffield – Until Midland Main Line Electrification.

Some of these like the Devon lines, could be served by Class 230s. Unless it was decided to install  a short stretch of third-rail electrification at Exeter, to charge the Aventra IPEMUs.

I think that until proven otherwise,Class 230s trains may join the pile of heroic failures. The Aventra IPEMU can do many of its routes and would be so much better.

Would you prefer a refurbished Ford to a new Jaguar?

Property Development

This may seem a long way from electric trains, but my travelling companions and their eyes like cash registers, got me thinking.

Let’s take an isolated town or city served by a tired branch line or crap trains. Lowestoft, Scarborough, Bury St. Edmunds, Weston Super Mare or Barrow-in-Furness for example. One of my companions suggested the latter!

In many cases, there is a package to be put together of new electric trains, rebuilding the area around the station with new commercial and residential development, that the local authority would find attractive. If the trains were sexy new electric ones, that could take you a lot further than the next large town, they would up the value of the package to the local authority considerably.

These packages would be very easily funded by say large insurance companies, as all the risks are well known and predictable. Once Aventra IPEMUs have proved themselves in service, they will have a risk profile on investment.

Political Considerations

Not my field!

But consider.

  • Replacing Pacers in many places is just putting in new trains. In others, it’s using the better examples of the displaced diesel multiple units.
  • There are arguments to perform electrification in a series of smaller projects, that minimise disruption to passengers, train companies and services.
  • Will any politician object to new British-built trains appearing in large numbers? Especially in his or her patch!
  • Some people object to all of money spent on the railways. Reducing the money spent can only give political advantage!
  • New trains are visible, schemes like Great Northern Great Eastern Joint Line or ERTMS are not!
  • In many parts of the UK, there is a perception that London gets all the investment . With Aventra IPEMUs the investment is spread around.

But surely the biggest political factor, is that elected representatives will get much greater control of the railways in their area.

Problems

Would politicians and people think that their train service couldn’t possibly be improved by a Mickey Mouse concept of large milk-floats with seats?

Bombardier have financial problems and probably not enough capacity in Derby.

Conclusion

I think the concept could be mind-blowing and could transform the UK.

I can’t believe that all this has not been put together before and this led me to the trial of the Class 379 BEMU, which I thought until I rode it and looked at the maths and physics would be a total disaster. There’s a BBC video.

What do the three partners get out of it?

  • Bombardier are hoping the technology will sell more trains, other than the few trams, they’ve sold to Nanjing.
  • Network Rail remove a lot of difficult lines from the need for electrification. No more dealing with Nimbys, bats, newts, terrible ground conditions and the militant wing of the heritage lobby.
  • Abellio at present have three franchises with a lot of lines that could use trains able to run for sixty miles without an external power source. They must know the likely benefits of introducing a new electric service and how much new trains would return.

It does seem that using Aventra IPEMUs is one of these things that just seems too good to be true!

But then if you understand the physics of rolling resistance of steel wheels on steel rails, the improving capabilities of modern energy storage and what modern automatic control systems can perform, it all looks to be not magic but superb engineering from many different fields coming together.

It has all the aura of one of those brilliant concepts put together in a pub, whilst under the influence of copious amounts of alcohol and drawn and written down on the back of those special fag packets and envelopes that engineers use.

I must admit, that I can’t understand, why someone hasn’t done it before.

The only reason I can think of, is that countries like France, Germany, Italy and Japan have had electrified railways for years and so they don’t have the problems we have of unelectrified railways.

An Alternative Approach To Provide A Local Metro Network

The UK rail industry is looking at the creation or upgrading of three local metro networks Bristol, Cardiff and Teesside. You could also argue, that they are seriously thinking about local networks out of Birmingham, Leeds, Manchester, Newcastle, Nottingham and Sheffield.

The Objectives Of A Metro Network

So what do passengers and train companies want to see in a metro?

I would say that the most successful metro lines we have created in the last few years have been the London Overground lines.

They operate under the following rules and principles.

  • Quality electric trains – Quality diesels would be fine in some places
  • Frequencies of four trains an hour. – Two or three trains per hour might suffice.
  • Clean stations, many of which are step-free.
  • A station improvement program.
  • Reliable service.
  • Visible staff on stations from first to last trains.
  • Extensive and visible information and maps.
  • Touch in and out ticketing with bank cards.
  • Good links to local buses.

The major problem of the Overground is that the trains keep needing to be lengthened, as they get crowded. The Class 378 trains started at three-cars and are now five.

Birmingham, Glasgow, Leeds and Liverpool seem to be using similar principles.

So how do three proposed metro networks stack up?

Cardiff

Let’s look at the electrification of the Cardiff Valleys Lines. According to the Wikipedia, the cost of the electrification is £350million.

I just wonder, if the scheme could be made more affordable, if the project was redesigned to use Aventra IPEMUs. The trains would obviously need sufficient electrification at Cardiff and Newport, so that they would leave the coast for their trips up the valleys with a full charge. Coming down wouldn’t be a problem and as the trains have regenerative braking, they would even charge the batteries.

Extensive testing would be easy once the current is switched on at Cardiff in a couple of years time and the clincher would be if an Aventra IPEMU could take a full load of Welshmen up to Merthyr Tydfil or Ebbw Vale after an international rugby match at the Millennium Stadium.

The scope of work would be greatly reduced.

  • Upgrading all stations to take a four car train.
  • Upgrading of the track layout and signalling, so that four car-trains could use each branch in an efficient manner.
  • There may be a need for some selective electrification, to ensure trains left fully charged, or for other operational reasons concerning diversions from the South Wales Main Line or for freight.

There are advantages to this approach.

  • Passengers get shiny new four-car trains, instead of refurbished hand-me-downs.
  • As money would be spent on trains, track and signalling rather than electrification, this could mean more trains and increased frequencies on the lines.
  • The Aventra trains could also take over some longer distance services to Bristol, Cheltenham, Fishguard and Gloucester.
  • Much of the network, probably only needs minimal upgrades to track and signalling.
  • There would be little or no heavy construction work in difficult places.
  • Much of the construction work on the stations has probably been completed.
  • There would be few line closures during the construction phase.
  • Bridges and tunnels that are not large enough to accept the overhead wires can be left as they are, unless the line is being opened up for freight traffic running to a larger gauge.
  • A higher proportion of the work to do will be general construction, rather than specialist overhead line installation, where there is a chronic shortage of engineers.
  • There is little scope for something to go seriously wrong.
  • The major source of delay would be late delivery of the Aventra IPEMU trains, but this would only mean that the diesel trains that currently work the line, would continue to serve the line for longer.

It strikes me that this approach has only one loser – the construction companies, who have helped create the electrification fiasco we have in this country. Passengers, train companies and the Welsh economy would all benefit!

According to this article on Global Rail News, London Overground’s contract for 45 Aventra trains is worth £260million. This works out at around £5.8million for each train. If the Aventra trains could work the Cardiff Valley Lines, with a little bit extra for the batteries or other energy storage device, twenty trains would probably cost around £140million or £7million a train.

I don’t know how many four-car trains they’d need to work the Valley Lines, but surely there is a trade-off between electrification and Aventra IPEMUs.

I can’t believe that Network Rail are not looking at this alternative approach, where instead of spending money on expensive and difficult electrification, the money is spent on shiny new trains built in a nice warm factory.

Teesside

The Tees Valley Metro is rather stillborn. The only thing that happened was the creation of James Cook station.

But there are two small electrification projects that could happen in the area in the near future.

  • Hitachi are building electric trains at Newton Aycliffe and this will probably mean that the Tees Valley Line will at least be electrified between the Hitachi factory and the East Coast Main Line at Darlington.
  • Plans exist to electrify between Middlesbrough and the East Coast Main Line, so that the town could benefit from a much improved train service.

If say this electrification were to be sufficient so that Aventra IPEMUs could be fully charged as they travelled from say Saltburn to Bishop Auckland, Phase 1 of the proposed Tees Valley Metro would get the new trains it will need.

Improve the stations and add a few new ones and you’d have a local railway to rival any in the UK.

In some ways if Aventra IPEMUs were used to develop the Metro everything would be in the opposite order to the traditional way of rebuilding a local line.

Normally, you close a line at great inconvenience to everyone, do a lot of construction and then spend months testing the new trains or trams, before a grand opening.

Compare this to upgrading a new line to run Aventra IPEMUs,

  1. Any work on the line to perhaps lengthen platforms and passing loops, and update signalling would be done first.
  2. Provided there is enough electrification to charge the trains, Aventra IPEMUs can be introduced alongside the existing trains, as they arrive from the factory and drivers and other staff have been trained.
  3. Adding new stations, is just a series of small well-defined construction projects, programmed to be done at convenient times and according to the budget.
  4. Other existing lines can be added to the system, if they are within the capability of the train and the platforms, track and signalling can accept the new trains.

A local network can be built by stealth in a series of small steps.

In Teesside’s case, you would certainly add the Phase 2 of the proposed Teesside Metro between Nunthorpe and Hartlepool.

An interesting possibility would be the Esk Valley Line to Whitby, if the Aventra IPEMU could manage the distance. If it couldn’t a Vivarail D-train certainly could.

Looking at the map, I feel that an Aventra IPEMU could be used on the Northern Rail service from Hexham via Newcastle, Sunderland, Hartlepool and Middlesbrough to Nunthorpe. It would charge the batteries running through Middlesbrough and Newcastle, and I don’t think any of the unelectrified stretches of line are more than thirty miles.

Bristol

Bristol has plans for creating a Metro, based on the two stations at Bristol Temple Meads and Bristol Parkway, which will be electrified (hopefully!) in the near future.

There are lines going all over the place providing services from outlying suburbs and towns to the centre.

Bristol has an opportunity to create a metro in the area, by upgrading all of the lines so they can take four-car trains, with longer platforms and updated track, signalling and stations. But in common with the rest of the country, there isn’t really any sensible trains available, although services could be developed using a collection of Pacers, D-trains and dodgy diesel unit.

However, once the two main stations are electrified, when the budget allows, Aventra IPEMUs could be introduced to the network.

So instead of one massive and expensive project, the metro is created in a series of small steps that don’t inconvenience passengers or train companies.

Other Services

When I discussed Teesside, I said this.

Looking at the map, I feel that an Aventra IPEMU could be used on the Northern Rail service from Hexham via Newcastle, Sunderland, Hartlepool and Middlesbrough to Nunthorpe. It would charge the batteries running through Middlesbrough and Newcastle, and I don’t think any of the unelectrified stretches of line are more than thirty miles.

How many other lines and services fall into this category of lengths of electrified line joined by no more than a total of sixty miles of unelectrified line that can easily be bridged by an Aventra IPEMU running on batteries?

I think these lines could fit the profile.

  • Blackpool South to Colne – When Blackpool electrification is finished
  • Carlisle to Newcastle
  • Hexham to Middlesbrough
  • Liverpool and Manchester Victoria to Leeds, York and Newcastle – The gap is just 43 miles
  • Liverpool Lime Street to Manchester Oxford Road via Warrington Central

Many are currently served by Pacers and others are served by diesel multiple units like Class 150 or Class 156 trains, that could in turn replace Pacers.

The most significant line is the TransPennine route from Liverpool to Newcastle, which could really transform travel by being run by four-car Aventra IPEMUs rather than inadequate three-car Class 185 diesel trains.

Someone at Bombardier has done a very good job in designing a train to circumvent the problems of electrification in the UK.

Project Costs And Cash Flows

I would be interested to see properly audited figures for the traditional electrification approach and one using Aventra IPEMUs.

There are surely various benefits that the Aventra IPEMU approach will bring to the costs.

  • The costs of the trains will be just a matter of negotiation, whereas the cost of electrification is not so predictable.
  • Enlarging bridges and tunnels to take the overhead wires, is an expensive process and often results in unexpected problems, that cost a fortune to solve. With the Aventra IPEMU, most infrastructure can be left untouched, unless it needs to be replaced anyway.
  • Most construction to accept the new trains, will be small projects, that can be handled by any competent construction company, whereas overhead line installation is a specialist construction job.
  • Electrification often seems to attract those who object to the overhead line equipment spoiling the view of an important rural landscape or cityscape. Aventra IPEMUs only need sufficient to charge the batteries.
  • With the Aventra IPEMU approach some new trains could be working on the network much earlier than they would be under a traditional approach. In some projects, will this have a beneficial cash flow?

I also come to the conclusion, that the Aventra IPEMU approach is more likely to deliver an affordable project on budget to an agreed time-scale, as the risk profile of electrification is so much worse than building a train on a production line in a factory.

One of the benchmarks of good project management is being able to deliver what is agreed. I believe that an Aventra IPEMU approach is much more likely to hit targets, as there is much less to go wrong.

Railways in the UK need a succession of successful projects, that impress engineers, train companies and passengers alike.

What better way to restore their credibility than for Network Rail, to deliver a series of projects that give millions of passengers efficient new electric train services all over the country.

Have We Got Enough Trains?

In Who Will Be First To Order Vivarail D-Trains?, I came to the conclusion that as the various Pacers need to be replaced, that we’re going to have to work hard to fill the enormous gap.

If you summarise possible requirements for D-Trains to replace Pacers and perhaps sort out the Class 153 trains, you get the following.

East Anglia – 3 to replace inadequate Class 153s

London Midland – 4 to replace inadequate Class 153s, 2 for the Coventry Arena shuttle

East Midlands – 8 to replace inadequate Class 153s, 2 for Robin Hood

Great Western Railway – 8 to replace Class 143 Pacers

Wales – 30 to replace inadequate Class 142 and Class 143 Pacers, 2 for Heart of Wales Line

Northern Rail – 50 to replace inadequate Class 142 Pacers

That totals up to a hundred and three and it assumes that all of the Class 144 Pacers can be upgraded to Class 144e trains and that North Western electrification releases a few good diesel trains to replace Pacers.

There is only a maximum of seventy-five D-Trains. So without any other sources of new trains, we’re definitely in the doo-dah.

So what other sources of good quality diesel or other self-powered trains are there, that we could use to solve this crisis, that will happen, when the inadequate trains hit the brick wall of access and disability regulations in 2019/2020.

The Aventra IPEMU

The Aventra is Bombardier’s successor train to the ubiquitos Electrostar and it has already been ordered for Crossrail and the London Overground.

Bombardier have told me, that all Aventras can be delivered with provision for a battery to allow them to run for up to 60 miles independently of the power supply. This is all based on the technology demonstrated in a BEMU trial with a Class 379 train.

These trains are now called Independently Powered Electric Multiple Units  or IPEMUs

The Aventra IPEMU has lots of advantages.

  • It is a modern four-coach electric train with everything passengers and train companies expect, that can bring the benefits of electrification to many places without putting up any wires or laying any third rails.
  • It is normally an 100 mph train, but some Electrostar versions are faster than this. If it was a 110 mph train, it could mix it up something like the West Coast , East Coast  or Great Western Main Lines and then go to an important place just a few miles from the main route, like Chester, Middlesbrough or Oxford.
  • The low-speed performance on batteries is the same as the standard train, but with a range of only sixty miles.
  • The train has sufficient performance to handle cross-country lines like Newcastle to Carlisle with electrification at both ends, that might be difficult to electrify.
  • In some places using an Aventra IPEMU might be more affordable and much quicker to implement than full electrification.
  • The trains will probably be available from 2018 or so, when current orders are completed.
  • If we end up with too many of the IPEMU variant, the batteries are just removed and probably with a change of software, we have the standard train.

We’ll be hearing a lot about IPEMUs in the future.

There are already rumours that Great Western Railway are going to order some IPEMU trains.

I suspect the biggest problem with these trains, other than demonstrating that trains powered by batteries are not some Mickey-Mouse idea, is that producing enough of them will be challenging for Bombardier.

As the Crossrail order can’t be delayed, I do wonder whether if the pace of delivery of the forty-five Aventras for London Overground will be slowed., after perhaps the eight for Gospel Oak to Barking are delivered, to allow other routes to have Aventra IPEMUs.

Vivarail D-Train, Class 144e Train Or Aventra IPEMU

There are three possible new or refurbished trains that can help to fill the gap of a lack of independently powered trains and help to replace all the trains that will have to be retired in 2020.

So how do they compare?

  • The Vivarail D-train is a rebuilt London Underground D78 Stock train powered by a number of Ford Transit engines. It may turn out to be successful train, but the politicians are against it. I see it no more than providing some short term capacity or fulfilling unusual needs in particular places.
  • The Class 144e Train is a Class 144 Train that has been rebuilt by Porterbrook. But it is obviously a Pacer! They may be produced as an affordable stop-gap.
  • The Aventra IPEMU is a serious train built to the highest and most acceptable standards, whose one disadvantage is that it needs to have access to overhead electrification at times, to charge the batteries! Stop-gap they are not and if the batteries are removed, it becomes the standard Aventra.

My choice as a passenger would be the Aventra, although I would ride in the others out of curiosity.

Electrification

Electrification will be the major source of good quality diesel trains, as these are often no longer needed after a line is electrified.

As a simple example consider the Gospel Oak to Barking Line, which on electrification will release eight rather nice and fairly new Class 172 diesel trains.

North Western Electrification

The North Western Electrification between Manchester and Preston and Preston to Blackpool is in trouble, but if this can be brought on track, so that Manchester to Preston is completed in December 2016 and Preston to Blackpool is completed in 2017, these lines can be run by refurbished Class 319 trains and a number of Pacers will not be needed and some Class 150 and Class 156 trains will be released for service elsewhere.

Everybody blames Network Rail, but it seems the problem is the same one faced by George Stephenson and his fellow engineers in Victorian times – the nature of the land. This is a recent report from the Manchester Evening News about more problems in the Farnworth Tunnel, which is being enlarged. This extract sums up the problems.

Engineers have been hindered by ‘large swathes of sand’, which are proving difficult to bore through.

The sand means it is no longer possible to safely excavate at the same time as grouting sections of the tunnel, as the sand pours down.

The problem first reared its head on August 14, when running sand created a hole which required 35 tonnes of grout to fill it.

Then on August 27, a collapse meant engineers had to remove 100 tonnes of sand by hand.

Let’s hope that the engineers are getting the overhead line equipment up on time.

But I do think some very experienced engineers are wondering, why they didn’t order trains, that could run on the existing infrastructure. On the other hand the Farnworth Tunnel was probably a problem, that could have bit the railway in half at any time.

I think it is essential that other lines in the North West are electrified as soon as possible, so that more Class 319s can replace Pacers and release Class 15X trains (A mixture of 150 and 156 trains!).

This is a map of the proposed electrification in the North.

Northern Electrification Map

Northern Electrification Map

There are various connecting lines around Liverpool, Manchester and Preston, on which electrification works have not yet started, but have certainly been talked about.

Electrifying these lines would certainly get rid of a few Pacers and release some Class 15X trains for refurshment and use elsewhere.

However, as there is established electrification at Liverpool, Manchester and Preston, it might be more affordable and quicker to use a few Aventra IPEMUs on these lines until the electrification is completed.

Manchester To Leeds Electrification

The Manchester to Leeds electrification has now been paused and it is likely that it will not be completed in the next ten years.

The line has its problems as the three-car Class 185 trains, that work the line, are totally inadequate for the route.

The distance by rail between Manchester and Leeds is 43 miles. When I saw this, I didn’t believe it, but it’s all in this article in the Guardian.

So this means that if you want to run an electric train between Liverpool and Manchester to Leeds, York and Newcastle, the Aventra IPEMU would bridge the gap with ease. The test version of the Aventra IPEMU was a modified Class 379 Train. Similar versions of these like the Class 387 Train are 110 mph trains, so could we see an Aventra IPEMU with such a top speed?

In other words the North Transpennine route could be electrified using four-car 110 mph Aventra IPEMUs. They would certainly be able to serve Newcastle and Middlesbrough, but Scarborough and Hull might still need to be operated by diesel trains.

It would also appear that Aventra IPEMUs could also bridge the gap between Leeds and Manchester Victoria on the Caldervale Line.

This would mean that all stations between Leeds and Manchester on both routes could be served by electric Aventra IPEMUs, if the line was not electrified.

Great Western Electrification

The electrification of the Great Western Main Line is important in solving the train crisis for several reasons.

  • If the electrification of the Great Western can be completed as far as Swindon and Newbury, this might release some of the 36, two- and three-car Class 165 trains or the 21, three-car Class 166 trains. These are in good condition and every train company will want a few to provide modern services.
  • Once electrification is completed to Bristol and Cardiff and Class 800 and Class 801 trains are running on the route, will release a number of InterCity 125s. Some are ear-marked for Scotland to provide flagship services and I’m sure that train companies will find uses for the rest.
  • Electrification to Cardiff will enable electrification of the Cardiff Valleys Lines. But the Valleys electrification needs the new trains to be delivered for Crossrail and/or the London Overground, so that the Class 315 trains can be refurbished and cascaded.

This report in Construction News entitled Crossrail, Thameslink, Great Western and North-west identified as priorities in Network Rail report says this.

The report into the planning of Network Rail’s £38.5bn improvement plan is expected to be released next month.

Sir Peter has identified Crossrail, Thameslink, Great Western and the North-west electrification as the four key “priority projects” for Network Rail, according to sources close to the report.

So it looks like the Great Western and North Western projects might get the resources to finish in time to allow cascades to release trains to help solve the shortage of train problems everywhere.

Scottish Electrification

Although the train shortage is more pronounced in England and Wales, Scottish electrification could give the rest of the UK a helping hand.

In the Wikipedia entry for Abellio ScotRail there is a section entitled Future. This is said.

Abellio ScotRail will introduce a fleet of 46 three car and 24 four car Hitachi AT200 electric trains from December 2017, to operate services on the lines being electrified as part of the Edinburgh to Glasgow Improvement Programme, if it granted a three-year optional franchise extension, it will order a further 10 three car units.

Abellio ScotRail will also introduce 14 four-carriage and 13 five-carriage refurbished High Speed Trains by December 2018 on longer-distance services between Edinburgh, Glasgow, Aberdeen and Inverness. This is contingent on the rolling stock being released by First Great Western, with suggestions in July 2015 that the electrification of the Great Western Main Line was running 12 months late.

This new rolling stock will result in 10 Class 156, eight Class 158 and 34 Class 170s returning to their leasing companies.

So when the new Hitachi trains are delivered by the end of 2018, there could be around fifty diesel trains available to help out in England and Wales.

It is also another reason why electrification of the Great Western must be completed, as without it, Scotland won’t get the High Speed Trains.

Gospel Oak To Barking Electrification

The eight Class 172 trains on the Gospel Oak to Barking Line will be released when that line is electrified.

But who knows when, that will happen?

As the services on the line could be provided by Aventra IPEMUs charging from the electrification at Barking, I do wonder if this should be done to release the Class 172 trains as early as possible. The electrification of the line would then be done at a more relaxed pace, whilst a full service was provided by the Aventras.

Pushing The Train Operating Companies To Help Themselves

In the last few months, some of the franchises have been extended or advertised for new franchisees.  And I think it is true to say, that the Department for Transport, is expecting that the train companies do something about improving the service.

Perhaps this paragraph from Transforming The North’s Railways is the most significant.

We are looking for a complete modernisation of the Northern rolling stock fleet, which will involve replacing Pacer trains completely by 2020 and delivering high quality modern trains for passengers. Bidders’ rolling stock plans must include at least 120 new-build carriages for use on non-electrified routes. The new carriages that will be introduced on the Northern network, along with the release of diesel units following the introduction of electric trains on newly-electrified routes, will enable the replacement of the Pacer units. Existing electric and diesel trains on Northern will receive a complete modernisation to make them ‘as new’ as soon as practicable after franchise start, with the emphasis that the design of new and existing interiors should feel thoroughly modern and focus on passenger comfort.

One hundred and twenty new build carriages for non-electrified routes either means something like sixty two-car diesel multiple units, thirty four-car Aventra IPEMUs or perhaps a mixture of the two. I don’t thin it means D-Trains or Class 144e Trains.

With Jeremy Corbyn threatening to nationalise the railways, it does seem the train companies are being told to sharpen up their acts significantly.

I think we’ll see more innovation and better services offered in the next few years.

Class Is Permanent

When Chiltern Railways wanted trains to run a high standard of service between London and Birmingham, they turned to locomotive-hauled Mark 3 coaches.

The coaches were refurbished to a very high standard, where every passenger can look out of the window, as shown in Hauled By A Diesel Locomotive To Birmingham. They even have sliding doors and modern toilets that meet all current and known future regulations.

And of course, they still have one of the finest ride qualities of any train in the world.

This is said on the Wikipedia entry for Abellio ScotRail.

Abellio ScotRail will also introduce 14 four-carriage and 13 five-carriage refurbished High Speed Trains by December 2018 on longer-distance services between Edinburgh, Glasgow, Aberdeen and Inverness. This is contingent on the rolling stock being released by First Great Western, with suggestions in July 2015 that the electrification of the Great Western Main Line was running 12 months late.

High Speed Trains are formed of two Class 43 locomotives and an appropriate number of Mark 3 coaches.

I would assume the coaches will be refurbished very much like the Chiltern examples with a high class interior, sliding doors and modern toilets, so they meet all current and known future access, disability and environmental regulations.

Terry Miller’s magnificent design, that was built between 1975 and 1988, just seems to keep putting off the inevitable. I wouldn’t bet against some Mark 3 coaches still being in regular service for a hundred years.

Despite their age, there are still a lot of Mark 3 coaches in regular service. I’m not sure how many, but there are over 800 in InterCity 125 sets.

In addition to the superb Chiltern Class 68 locomotive-hauled sets, there are also several sets used by Abellio Greater Anglia on Liverpool Street to Ipswich and Norwich services, where they are hauled by Class 90 locomotives.

These Greater Anglia sets need upgrading with sliding doors and modern toilets, if they are to stay in service past 2020.

The next operator for this franchise is being given tough conditions, which include putting modern trains on the flagship route and running some services in ninety minutes from Norwich to London and sixty from Ipswich. The question has to be asked if this would be possible with a modern locomotive and refurbished Mark 3 coaches!

I think there is a high chance that the winning bidder for the next Greater Anglia franchise will still be using refurbished Mark 3 coaches between Liverpool Street, Ipswich and Norwich.

The new franchisee will have to offer lots of new services and three possibilities have been run in my lifetime.

  • Liverpool Street and Great Yarmouth, via Cambridge, the new Cambridge Science Park station and Norwich.
  • Liverpool Street and Peterborough via Colchester, Ipswich, Bury St. Edmunds and Ely.
  • Liverpool Street to Lowestoft via Colchester and Ipswich.

They have a problem, in that sections of these routes are not electrified. There are four possible solutions.

  • Run the routes in such a way that an Aventra IPEMU can service it. A possibility!
  • Buy a few Class 800 electro-diesel trains, which would probably be made in Japan by Hitachi. Expensive but possible!
  • Get a few more sets of refurbished Mark 3 coaches and haul them with a Class 88 electro-diesel locomotive. No problem and in style!
  • Use InterCity 125s. Possibly, but 100% diesel!

The only options that could be done quickly would be to use the Class 88 or InterCity 125s.

The latter would work, but surely a mainly electric modern solution is probably better and more acceptable to politicians.

I would also never rule out more sets of Mark 3 coaches being used around the country after refurbishment. The only problem is something environmentally-friendly to haul them!

The Scottish solution of shortened High Speed Trains could also be used.

Aventra IPEMUs Running From Or Between Electrified Hubs Or Lines

Many branch lines or secondary routes meet the following conditions.

  • They are electrified at one or both ends.
  • The electrification is sufficient to charge an Aventra IPEMU’s battery, as it waits to return or passes along the line.
  • The non-electrified sections of the line are short enough to be handled by an Aventra IPEMU.

Examples of lines suitable for an IPEMU include.

  • Newcastle to Carlisle
  • Manchester to Leeds
  • Cambridge to Ipswich
  • Coventry to Nuneaton
  • Carnforth to Barrow-in-Furness
  • Norwich to Yarmouth

I think that once the Aventra IPEMU concept is proven, then we’ll see them increasingly used around electrified lines.

There is a long list of places, where branch and secondary routes meet main electrified lines.

  • Birmingham
  • Carlisle
  • Coventry
  • Crewe
  • Darlington
  • Doncaster
  • Ely
  • Ipswich
  • Leeds
  • Liverpool
  • Manchester Piccadilly
  • Manchester Victoria
  • Newcastle
  • Norwich
  • Peterborough
  • Preston
  • Wolverhampton
  • York

This list will hopefully be increased, when the Great Western Main Line is electrified.

  • Bristol
  • Cardiff
  • Reading
  • Swansea

I have written An Alternative Approach To Provide A Local Metro Network, which investigates how  Aventra IPEMUs can be used to provide electric trains on lines without full electrification.

The only area of the country that will lack electrified hubs in a few years will be the East Midlands Main Line and the far South West and the Northern parts of Scotland and Wales.

So surely, it is important that we electrify the Midland Main Line to bring electrification to the important hubs of Derby, Nottingham and Sheffield, so we can use Aventra IPEMUs to provide electric trains on their local lines.

Conclusions

It’s tight, but I think it’ll be alright in 2020, but there are certain things we must do.

  1. Use no more than a handful of Vivarail D-Trains to provide services on some far-flung lines.
  2. The Great Western, North Western and Scottish electrifications must be completed on time.
  3. Use the Mark 3 coaches intelligently
  4. Use new Aventra IPEMUs to side-step electrification in places like, the electrification gap between Manchester and Leeds and the Cardiff Valleys Lines.
  5. Use new Aventra IPEMUs to provide services around electrified hubs.
  6. Scrap all the Pacers except possibly upgraded Class 144e trains.
  7. Upgrade the Class 150, Class 153 and Class 156 trains.

I think it’ll be interesting to see how the companies jump.

Platforms 11 and 12 At Stratford

In December this year, an service hourly service called STAR will be started between Stratford and Angel Road along the Temple Mills Branch of the Lea Valley Lines via Lea Bridge, Tottenham Hale and Northumberland Park stations. Wikipedia says this about services to and from the Angel Road station.

Angel Road is only served by a number of trains every weekday to and from Stratford. No services operate at the station on weekends or public holidays. However, from December 2015 Angel Road will receive an hourly service to Stratford that will start here and vice versa, the service will be known as (STAR).

STAR services will obviously call at the new Lea Bridge station, when it opens next year.

I shall probably use the service occasionally, when I need to get home from Stratford, as Lea Bridge station is on the 56 bus route that passes by my house.

At Stratford, there are two platforms that have been positioned to give easy access to the Temple Mills Branch through Lea Bridge and Tottenham Hale and onwards to Stansted Airport. I took these pictures of the platforms.

They sit at the end of the two London Overground platforms, which are the Eastern terminus of the North London Line. You can see two Class 378 trains peeking out from underneath the rusty bridge. (Not my name, but an East London nickname, I’ve heard from locals and station staff!) This Google Map shows the layout of the platforms.

Stratford Platforms 11 And 12

Stratford Platforms 11 And 12

In the map, platforms 11 and 12 curve away to the North from underneath the rusty bridge, which connects Eastfield to Stratford town centre.

Platform 11 is the Easternmost platform and is used as the terminus of the Stratford to Bishops Stortford service, which has been rumoured many would like extended to Stansted.

Platforms 1 and 2 for the North London Line are connected to the unused Platform 12, by a simple walkway, so in the future if Platform 12 is used for the STAR services, passengers going from anywhere on the North London Line to Tottenham Hale or Angel Road would just have an easy interchange.

As the STAR service will initially be an hourly service and the Bishops Stortford service is half-hourly and they run from platforms connected by a subway, I can’t help feeling that this will be an arrangement that won’t last long, before it is improved.

Suppose you arrive at Stratford wanting to get home to your house near Lea Bridge station and just miss the hourly train. Do you wait an hour for another train or catch the Bishops Stortford train, that will probably stop at Lea Bridge, after the new station opens?

It would be so much easier, if the two local services started from an shared island platform or at lest two platforms with a level walk between them.

This is going to get very complicated, if some of the plans for Stratford services up the Lea Valley are implemented.

  • I’ve read several times, that reinstatement of the link to Stansted Airport is an aspiration of many, especially as Stratford is close to the Olympic Park and it is an important rail interchange and a terminus for two branches of the DLR and the Jubilee and North London Lines.
  • There are also aspirations to start a direct service between the Chingford branch and Stratford using the reinstated Hall Farm Curve.
  • With all of the housing, business and leisure developments along the lower Lea Valley, it will not be long before an hourly STAR service is inadequate.
  • If the Hall Farm Curve is reinstated, would there be a need to run services between the Chingford branch and the North London Line?
  • There is also the Crossrail effect, which in the Lea Valley’s case could not be just Crossrail, but Crossrail 2 if that ever gets built.
  • Perhaps unlikely now, but I feel that at some point the Dalston Eastern Curve will be reopened, so enabling services between say Walthamstow to South London.
  • Is there a need to better connect Stratford International station to the main regional complex?

I can’t help feeling that the layout of Platforms 11 and 12 will at some time not be able to handle all the Lea Valley services.

I suspect though there may be an innovative solution.

Look at the Google Map and you see that the Temple Mills Branch passes over the deep hole of the International station. I wrote Is This The Most Unwelcoming Station In The UK? about that dreadful station.

So could two or three bay platforms to serve the Lea Valley and Stansted Airport, be built alongside the Temple Mills Branch, as it passes over the International station?

This Google Map shows Stratford International station.

The building at the bottom right is also shown on the previous map that shows Platforms 11 and 12.

If the extra platforms were built over the Eastern end of the International station, it would enable the following.

  • A new Eastern entrance to the International station could be created to give better connections between International and High Speed services from Stratford International and all the other services at Stratford Regional station.
  • Crossrail would have a step-free interchange to Eurostar and other International services, if those services stopped at the International station.
  • Interchange between Lea Valley and North London Line services, would be via a double Clapham Kiss, where passengers would just walk on the level to the other set of platforms.
  • There might be opportunities to extend or improve the connectivity of the DLR. The current DLR station is at the top left of the map.
  • Any direct services between the Temple Mills Branch and the North London Line would use the existing Platforms 11 and 12.

To get the connection right, the pedestrian links would have to be well-designed, but surely there is space to put a travelator effectively between the Regional and International stations.

Stratford International station would end up as what it should be, the International section of Stratford station.
