The Anonymous Widower

East Kilbride Electrification Underway

The title of this post, is the same as that of this article on Modern Railways.

These are the last two paragraphs.

As well as electrification, improvements on the line will include an upgrade of East Kilbride station, relocation of Hairmyres station 600 metres to the west, platform extensions and accessibility upgrades. The aim is to provide a four trains per hour eight-car electric service at peak periods. A parallel project will cover electrification between Busby Junction and Barrhead.

The Scottish Government’s plan is to decarbonise its passenger rail services by 2035, chiefly through electrification. It has recently been confirmed that partial electrification of the Borders and Fife Circle routes will follow after the East Kilbride and Barrhead lines, with battery EMUs deployed on these lines.

Because partial electrification is mentioned, it looks like Scotland is getting serious about using battery-electric trains.

This map clipped from Wikipedia, shows the section of the Glasgow South Western Line, that includes Kilmarnock station and the branch to East Kilbride station.

The route North of Strathbungo continues to Glasgow Central station.

Which Sections Will Be Electrified?

I will take each of the sections in turn starting at the North.

Between Muirhouse South And Busby Junctions

This sentence is from the Modern Railways article.

Contractor SPL will commence on-site activities between Muirhouse South Junction and Busby Junction, including piling and construction steelwork foundations to support overhead masts.

On the map, Muirhouse South Junction is to the North of Stratbumgo and Busby junction is clearly marked and is where the East Kilbride branch joins the main line.

This section of new electrification is only around two miles long.

This article on Rail Technology Magazine is entitled Network Rail: Strathbungo Locals Vote For New Footbridge.

There have been many bridge replacements for electrification, but this surely must be one of the first, where local people have voted for their preferred design.

The only other bridges on this section appear to be two substantial road bridges, where with any luck, it should be possible to squeeze the wires underneath.

Between Busby Junction And Barrhead Station

The other section listed for electrification is between Busby junction and Barrhead station.

This second section is only around 3.7 miles long and there are only two overbridges, both of which look modern.

Taking the two sections of electrification together they total under twelve track-miles and they are in a continuous straight line

I doubt, that together, they are the one of the world’s most challenging railway electrification projects.

Busby Junction and East Kilbride Station

There is no specific information about electrification between Busby junction and East Kilbride station.

  • The branch is 7.8 miles long.
  • There are fifteen overbridges on the branch.

In Plans To Introduce Battery Powered Trains In Scotland, Hitachi are quoted as saying that their trains will do sixty miles on batteries.

This should be more than enough range to run services to East Kilbride on battery power.

Barrhead and Kilmarnock Stations

There is no specific information about electrification between Barrhead and Kilmarnock stations.

  • The distance is 16.8 miles.
  • There are eleven overbridges between the two stations.

It would appear that Hitachi’s quoted sixty mile range, would be sufficient to enable battery-electric trains to run between the electrification at Barrhead and Kilmarnock station.

Operation

The various services between Glasgow Central and East Kilbride and Kilmarnock stations will probably operate as follows.

  • Glasgow Central To East Kilbride – Electrification for traction and battery charging to Crossmyloof station and then battery power.
  • East Kilbride To Glasgow Central – Battery power and gravity to Crossmyloof station and then electrification.
  • Glasgow Central To Barrhead – Electrification for traction all the way.
  • Barrhead to Glasgow Central – Electrification for traction all the way.
  • Glasgow Central To Kilmarnock – Electrification for traction and battery charging to Barrhead station and then battery power.
  • East Kilbride To Glasgow Central – Battery power to Barrhead station and then electrification.

Note.

  1. All power changeovers could be arranged to take place in stations.
  2. Gravity can be used to assist trains from East Kilbride to Glasgow Central.
  3. Glasgow Central and Barrhead services don’t need trains with batteries.
  4. The return trip between Crossmyloof and Glasgow central stations, should be more than enough to charge the batteries.

The project would appear to have been very well-designed for a fleet of battery-electric trains, with respect to reliability and electrical efficiency.

Onward To Carlisle And Stranraer

Hitachi’s system for discontinuous electrification, that I discussed in Solving The Electrification Conundrum, would appear to be ideal to extend electric trains to Carlisle and Stranraer.

Barrhead and Carlisle are 108 miles apart and Barrhead and Stranraer are 90 miles apart.

By adding two or three intermediate sections of 25 KVAC overhead electrification, it should be possible for electric trains to reliably travel between Glasgow Central and Carlisle or Stranraer.

Project Management

This electrification project could be a Project Manager’s dream.

Electrification projects in the UK can turn out to be nightmares, as if it can go wrong, it inevitably will.

But with this project, it appears that it is planned to get the often-troublesome job of erecting the gantries out of the way early.

The electrification between Muirhouse South junction and Barrhead station can even be completed first, so that passengers can see the benefit of electric trains and the electrification can be fully tested.

There are then a series of independent projects, that can be performed in the most convenient order.

  • Track upgrades.
  • Rebuild East Kilbride station.
  • Move Hairmyres station to its new position.
  • Platform extensions.
  • Improve accessibility.
  • Deliver the new battery-electric trains.

Note.

  1. It looks to me, that all of these smaller projects can be performed, whilst maintaining a full rail service on the railway. Doing that with conventional electrification usually results in some disruption.
  2. Late delivery of the battery-electric trains will not delay the overall project, if there are enough diesel multiple units to fill in.
  3. Passengers will see benefits and new facilities delivered in a stream, rather than all at once.

Similar processes can be used to extend the network to Carlisle and Stranraer.

Conclusion

This is a well-designed project.

London To Glasgow Train Journey Record Bid Fails By Just 21 Seconds

The title of this post, is the same as that of this article on ITV.com.

These are the first three paragraphs.

An attempt to break the 36-year-old record for the fastest train journey between London and Glasgow has failed.

Avanti West Coast’s Royal Scot train arrived at Glasgow Central 21 seconds behind the record of three hours, 52 minutes and 40 seconds set by British Rail in December 1984, according to rail expert Mark Smith, who was onboard.

Mr Smith, founder of Seat61.com, wrote on Twitter that a temporary speed limit on the track in Carstairs, South Lanarkshire, “cost us 90 seconds”.

It appears to be a valiant attempt that failed by a small margin.

I have a few thoughts.

The Trains

The British Rail 1984 record was set by an Advanced Passenger Train (APT) and today’s run was by a nine-car Class 390 train.

  • The design speed of the APT was 155 mph and that of a Class 390 train is 140 mph.
  • Service speed of both trains was and is 125 mph.
  • Record speed of the APT was 162 mph and that of a Class 390 train is 145 mph.
  • Both trains employ similar tilt technology to go faster.

At a brief look the performance of these two trains is very similar.

The InterCity 225

The InterCity 225 train is the ringer in this race to the North.

  • The design speed is 140 mph.
  • The service speed is 125 mph
  • The record speed of an InterCity 225 is 161.7 mph.
  • The train doesn’t use tilting technology.
  • The train was built after the APT around 1990.
  • The train holds the record between London Kings Cross and Edinburgh at thirty seconds under three-and-a-half hours.
  • To rub things in, one of these trains, even holds the London Euston and Manchester Piccadilly record.

But there can’t be much wrong with the InterCity 225 trains as a few are being brought back into service, whilst LNER are waiting for ten new bi-mode trains to be delivered.

Hitachi Class 80x Trains

The various variants of Class 800 trains run to Edinburgh and I’m sure they will run to Glasgow.

  • The design speed is 140 mph.
  • The service speed is 125 mph

If an InterCity 225 can go between Edinburgh and London in around three-and-a-half hours, I can’t see why these trains can’t.

Especially, as Hitachi seem to be able to produce versions like the Class 803 and Class 807 trains, which appear to be lighter and more efficient, as they don’t have any diesel engines.

A Small Margin

I said earlier that it was only a small margin between the times of the APT and the Class 390 train. But why was the InterCity 225 able to run between Kings Cross and Edinburgh at thirty seconds under three-and-a-half hours?

This section in the Wikipedia entry for the Class 91 locomotive is entitled Speed Record. This is the first paragraph.

A Class 91, 91010 (now 91110), holds the British locomotive speed record at 161.7 mph (260.2 km/h), set on 17 September 1989, just south of Little Bytham on a test run down Stoke Bank with the DVT leading. Although Class 370s, Class 373s and Class 374s have run faster, all are EMUs which means that the Electra is officially the fastest locomotive in Britain. Another loco (91031, now 91131), hauling five Mk4s and a DVT on a test run, ran between London King’s Cross and Edinburgh Waverley in 3 hours, 29 minutes and 30 seconds on 26 September 1991. This is still the current record. The set covered the route in an average speed of 112.5 mph (181.1 km/h) and reached the full 140 mph (225 km/h) several times during the run.

It looks from the last sentence of this extract, that the record run of the InterCity 225 train ran up to 140 mph in places, whereas the record run of the APT and today’s run by a Class 390 train were limited to 125 mph.

The Signalling

In the Wikipedia entry for the InterCity 225 train, the following is said.

Thus, except on High Speed 1, which is equipped with cab signalling, British signalling does not allow any train, including the InterCity 225, to exceed 125 mph (201 km/h) in regular service, due to the impracticality of correctly observing lineside signals at high speed.

Note.

  1. I have regularly flown my Cessna 340 safely at altitude, with a ground speed of around two hundred miles per hour.
  2. High Speed One has an operating speed of 186 mph.
  3. Grant Schapps, who is Secretary of State for Transport has a pilot’s licence. So he would understand flight instruments and avionics.

So why hasn’t a system been developed in the thirty years since trains capable of running at 140 mph started running in the UK, to allow them to do it?

It is a ridiculous situation.

We are installing full digital ERTMS in-cab signalling on the East Coast Main Line, but surely a system based on aviation technology could be developed until ERTMS  is ready. Or we could install the same system as on High Speed One.

After all, all we need is a system, to make sure the drivers don’t misread the signals.

But then the EU says that all member nations must use ERTMS signalling.

Didn’t we just leave the EU?

Conclusion

By developing our own in-cab digital signalling we could run trains between London and Scotland in around three-and-a-half hours.

The Japanese could even have an off-the-shelf system!

ERTMS sounds like a closed shop to give work to big European companies, who have lobbied the European Commission.

Through Settle And Carlisle Service Under Consideration

The title of this post, is the same as that of an article in the June 2021 Edition of Modern Railways.

This is the first paragraph.

Plans for a new Leeds to Glasgow through service via the Settle and Carlisle line are being developed, with CrossCountry and the Department for Transport starting to look at the possible scheme.

It sounds like a sensible idea to me.

The article also suggests the following.

  • CrossCountry is a possible operator.
  • CrossCountry are keen to improve services between Leeds and Glasgow
  • The trains could be InterCity 125s, freed up, by a the arrival of Class 221 trains from Avanti West Coast, when they receive their new Class 805 trains.
  • Maintenance of the trains wouldn’t be a problem, as this could be done at Neville Hill in Leeds or Craigentinny in Edinburgh.
  • Services could start in December 2023.

I have a few thoughts of my own!

The Route

The route between Leeds and Carlisle is obvious, but there are two routes between Carlisle and Glasgow.

Trains would probably choose a route and call at stations to maximise passenger numbers.

These stations are on the various routes.

  • Settle and Carlisle – Shipley, Bingley, Keighley, Skipton, Gargrave, Hellifield, Long Preston, Settle, Horton in Ribblesdale, Ribblehead, Dent, Garsdale, Kirkby Stephen, Appleby, Langwathby, Lazonby & Kirkoswald and Armathwaite
  • Glasgow South Western – Dunlop, Stewarton, Kilmaurs, Kilmarnock, Auchinleck, New Cumnock, Kirkconnel, Sanquhar, Dumfries, Annan and Gretna Green
  • West Coast Main – Motherwell, Carstairs and Lockerbie

There are certainly a lot of possibilities.

 Upgrading The InterCity 125 Trains

CrossCountry appear to have enough InterCity 125 trains to muster five in a two Class 43  locomotives and seven Mark 3 coach formation.

They may not be fully in-line with the latest regulations and there may be a need for a certain degree of refurbishment.

These pictures show some details of a refurbished Great Western Railway Castle, which has been fitted with sliding doors.

Will The InterCity 125 Trains Be Shortened?

Scotrail’s Inter7City trains and Great Western Railway’s Castle trains have all been shortened to four or five coaches.

This picture shows a pair of Castles.

Journey Times, Timetable And Frequency

The current journey time between Leeds and Glasgow Central stations via the East Coast Main Line is four hours and eight minutes with nine stops.

The Modern Railways article says this about the current service.

The new service would be targeted at business and leisure travellers, with through journey times competitive with road and faster than the current direct CrossCountry Leeds to Glasgow services via the East Coast main line.

I would expect that CrossCountry are looking for a time of around four hours including the turn round.

  • Stops could be removed to achieve the timing.
  • The trains could run at 125 mph on the West Coast Main Line.

This could enable a train to have the following diagram.

  • 0800 – Depart Leeds
  • 1200 – Depart Glasgow Central
  • 1600 – Depart Leeds
  • 2000 – Depart Glasgow Central
  • Before 2400 – Arrive Leeds

Note.

  1. A second train could start in Glasgow and perform the mirrored timetable.
  2. Timings would probably be ideal for train catering.
  3. Trains would leave both termini at 0800, 1200, 1600 and 2000.
  4. The timetable would need just two trains.

I also think, if a second pair of trains were to be worked into the timetable, there could be one train every two hours on the route, if the demand was there.

I certainly believe there could be a timetable, that would meet the objectives of attracting business and leisure passengers away from the roads.

Tourism And Leisure Potential

The Settle and Carlisle Line is known as one of the most scenic railway lines in England, if not the whole of the UK.

There are important tourist sites all along the route between Leeds and Glasgow

Many of the stations are used by walkers and others interested in country pursuits.

I believe that it is a route that needs a quality rail service.

Travel Between London and Towns Along The Settle And Carlisle Line

In Thoughts On Digital Signalling On The East Coast Main Line, I said this.

I think it is highly likely that in the future, there will be at least one train per hour (tph) between London Kings Cross and Leeds, that does the trip in two hours.

It may seem fast compared to today, but I do believe it is possible.

With a timely connection at Leeds station, will this encourage passengers to places along the Settle and Carlisle line to use the train?

What About the Carbon Emissions?

The one problem with using InterCity 125 trains on this route, is that they are diesel-powered, using a pair of Class 43 locomotives.

But then there are over a hundred of these diesel-electric locomotives in service, nearly all of which are now powered by modern MTU diesel engines, which were fitted in the first decade of this century.

Consider.

  • The locomotives and the coaches they haul have an iconic status.
  • Great Western Railway and Scotrail have recently developed shorter versions of the trains for important routes.
  • There are over a hundred of the locomotives in service.
  • Companies like ULEMCo are developing technology to create diesel-powered vehicles that can run on diesel or hydrogen.
  • There is plenty of space in the back of the locomotives for extra equipment.
  • MTU have a very large number of diesel engines in service. It must be in the company’s interest to find an easy way to cut carbon emissions.
  • I believe that the modern MTU diesel engines could run on biodiesel to reduce their carbon footprint.

And we shouldn’t forget JCB’s technology, which I wrote about in JCB Finds Cheap Way To Run Digger Using Hydrogen.

If they could develop a 2 MW hydrogen engine, it could be a shoe-in.

I believe that for these and other reasons, a solution will be found to reduce the carbon emissions of these locomotives to acceptable levels.

Conclusion

In this quick look, it appears to me that a Glasgow and Leeds service using InterCity 125 trains could be a very good idea.

Hitachi Trains For Avanti

The title of this post is the same as that of an article in the January 2020 Edition of Modern Railways.

The Bi-Mode Trains

Some more details of the thirteen bi-mode and ten electric Hitachi AT 300 trains are given.

Engine Size and Batteries

This is an extract from the article.

Hitachi told Modern Railways it was unable to confirm the rating of the diesel engines on the bi-modes, but said these would be replaceable by batteries in future if specified.

I do wonder if my speculation in Will Future Hitachi AT-300 Trains Have MTU Hybrid PowerPacks? is possible.

After all, why do all the hard work to develop a hybrid drive system, when your engine supplier has done it for you?

Would Avanti West Coast need a train that will do 125 mph on diesel?

The only place, they will be able to run at 125 mph or even higher will be on the West Coast Main Line, where they will be running under electric power from the pantograph.

If I were designing a bi-mode for 90 mph on diesel and 125 mph on electric, I would have batteries on the train for the following purposes.

  • Handle regenerative braking.
  • Provide hotel power in stations or when stationery.
  • Provide an acceleration boost, if required, when running on diesel.
  • Provide emergency power, if the wires go down in electric mode.

I’m sure MTU could work out a suitable size of diesel engine and batteries in an MTU PowerPack, that would meet the required performance.

Or maybe a smaller diesel could be used. An LNER Class 800 train has 1680 kW of installed power to maintain 125 mph. But the Great Western Railway versions have 2100 kW or twenty-five percent more, as their routes are more challenging with steeper gradients.

For the less challenging routes at a maximum of 90 mph between Crewe, Chester, Shrewsbury and North Wales, I wonder what level of power is needed.

A very rough estimate based on the speed required could put the power requirement as low as 1200-1500 kW.

As the diesel engines are only electrical generators, it would not effect the ability of the train to do 125 mph between Crewe and London.

There looks to be a virtuous circle at work here.

  • Lower maximum speed on diesel means smaller diesel engines.
  • Smaller diesel engines means lighter diesel engines and less fuel to carry.
  • Less weight to accelerate needs less installed power.
  • Less power probably means a more affordable train, that uses less diesel.

It looks to me, that Hitachi have designed a train, that will work Avanti West Coast’s routes efficiently.

The Asymmetric Bi-Mode Train

It looks to me that the bi-mode train  that Avanti West Coast are buying has very different performance depending on the power source and signalling

  • 90 mph or perhaps up to 100 mph on diesel.
  • 125 mph on electric power.with current signalling.
  • Up to 140 mph on electric power with in-cab digital signalling.

This compares with the current Class 221 trains, which can do 125 mph on all tracks, with a high enough operating speed.

The new trains’ different performance on diesel and electric power means they could be called asymmetric bi-modes.

Surely, creating an asymmetric bi-mode train, with on-board power; battery, diesel or hydrogen, sized to the route, means less weight, greater efficiency, less cost and in the case of diesel, higher carbon efficiency.

Carbon Emissions

Does the improvement in powertrain efficiency with smaller engines running the train at slower speeds help to explain this statement from the Modern Railways article?

Significant emissions reduction are promised from the elimination of diesel operation on electrified sections as currently seen with the Voyagers, with an expected reduction in CO2 emissions across the franchise of around two-thirds.

That is a large reduction, which is why I feel, that efficiency and batteries must play a part.

Battery-Electric Conversion

In my quote earlier from the Modern Railways article, I said this.

These (the diesel engines) would be replaceable by batteries in future if specified.

In Thoughts On The Next Generation Of Hitachi High Speed Trains, I looked at routes that could be run by a battery-electric version of Hitachi AT-300 trains.

I first estimated how far an AT-300 train could go on batteries.

How far will an AT-300 train go on battery power?

  • I don’t think it is unreasonable to be able to have 150 kWh of batteries per car, especially if the train only has one diesel engine, rather than the current three in a five-car train.
  • I feel with better aerodynamics and other improvements based on experience with the current trains, that an energy consumption of 2.5 kWh per vehicle mile is possible, as compared to the 3.5 kWh per vehicle mile of the current trains.

Doing the calculation gives a range of sixty miles for an AT-300 train with batteries.

As train efficiency improves and batteries are able to store more energy for a given volume, this range can only get better.

I then said this about routes that will be part of Avanti West Coast’s network.

With a range of sixty miles on batteries, the following is possible.

  • Chester, Gobowen, Shrewsbury And Wrexham Central stations could be reached on battery power from the nearest electrification.
  • Charging would only be needed at Shrewsbury to ensure a return to Crewe.

Gobowen is probably at the limit of battery range, so was it chosen as a destination for this reason.

The original post was based on trains running faster than the 90 mph that is the maximum possible on the lines without electrification, so my sixty mile battery range could be an underestimate.

These distances should be noted.

  • Crewe and Chester – 21 miles
  • Chester and Shrewsbury – 42 miles
  • Chester and Llandudno – 47 miles
  • Chester and Holyhead – 84 miles

Could electrification between Crewe and Chester make it possible for Avanti West Coast’s new trains to go all the way between Chester and Holyhead on battery power in a few years?

I feel that trains with a sixty mile battery range would make operations easier for Avanti West Coast.

Eighty miles would almost get them all the way to Holyhead, where they could recharge!

Rlectrification Between Chester And Crewe

I feel that this twenty-odd miles of electrification could be key to enabling battery-electric trains for the routes to the West of Chester to Shrewsbury, Llandudno and Holyhead.

How difficult would it be to electrify between Chester and Crewe?

  • It is not a long distance to electrify.
  • There doesn’t appear to be difficult viaducts or cuttings.
  • It is electrified at Crewe, so power is not a problem.
  • There are no intermediate stations.

But there does seem to be a very large number of bridges. I counted forty-four overbridges and six underbridges. At least some of the bridges are new and appear to have been built with the correct clearance.

Perhaps it would be simpler to develop fast charging for the trains and install it at Chester station.

Conclusion On The Bi-Mode Trains

It appears to me that Avanti West Coast, Hitachi and Rock Rail, who are financing the trains have done a very good job in devising the specification for a fleet of trains that will offer a good service and gradually move towards being able to deliver that service in a carbon-free manner.

  • The initial bi-mode trains will give a big improvement in performance and reduction in emission on the current Voyagers, as they will be able to make use of the existing electrification between Crewe and London.
  • The trains could be designed for 125 mph on electric power and only 90-100 mph on diesel, as no route requires over 100 mph on diesel. This must save operating costs and reduce carbon emissions.
  • They could use MTU Hybrid PowerPacks instead of conventional diesel engines to further reduce emissions and save energy
  • It also appears that Hitachi might be able to convert the trains to battery operation in a few years.
  • The only new infrastructure would be a few charging stations for the batteries and possible electrification between Chester and Crewe.

I don’t think Avanti West Coast’s ambition of a two-thirds reduction in CO2 is unreasonable and feel it could even be exceeded.

Other Routes For Asymetric Bi-Mode Trains

I like the concept of an asymetric bi-mode train, where the train has the following performance.

  • Up to 100 mph on battery, diesel or hydrogen.
  • Up to 100 mph on electrified slower-speed lines.
  • 125 mph on electrified high-speed lines, with current signalling.
  • Up to 140 mph on electrified high-speed lines, with in-cab digital signalling.

I am very sure that Hitachi can now tailor an AT-300 train to a particular company’s needs. Certainly, in the case of Avanti West Coast, this seems to have happened, when Avanti West Coast, Hitachi, Network Rail and Rock Rail had some serious negotiation.

LNER At Leeds

As an example consider the rumoured splitting and joining of trains at Leeds to provide direct services between London and Bradford, Harrogate, Huddersfield, Ilkley, Skipton and other places, that I wrote about in Dancing Azumas At Leeds.

In the related post, I gave some possible destinations.

  • Bradford – 13 miles – 25 minutes – Electrified
  • Harrogate – 18 miles – 30 minutes
  • Huddersfield – 17 miles – 35 minutes
  • Hull – 20 miles – 60 minutes
  • Ilkley – 16 miles – 26 minutes – Electrified
  • Skipton – 26 miles – 43 minutes – Electrified
  • York – 25 miles – 30 minutes

Note, that the extended services would have the following characteristics.

They would be run by one five-car train.

  1. Services to Bradford, Ilkley and Skipton would be electric
  2. Electrification is planned from Leeds to Huddersfield and York, so these services could be electric in a few years.
  3. All other services would need independent power; battery, diesel or hydrogen to and from Leeds.
  4. Two trains would join at Leeds and run fast to London on the electrified line.
  5. Services would probably have a frequency of six trains per day, which works out at a around a train every two hours and makes London and back very possible in a day.
  6. They would stop at most intermediate stations to boost services to and from Leeds and give a direct service to and from London.

As there are thirty trains per day between London and Leeds in each direction, there are a lot of possible services that could be provided.

Currently, LNER are only serving Harrogate via Leeds.

  • LNER are using either a nine-car train or a pair of five-car trains.
  • The trains reverse in Platforms 6 or 8 at Leeds, both of which can handle full-length trains.
  • LNER allow for a generous time for the reverse, which would allow the required splitting and joining.
  • All trains going to Harrogate are Class 800 bi-mode trains.

Note that the Class 800 trains are capable of 125 mph on diesel, whereas the average speed between Harrogate and Leeds is just 35 mph. Obviously, some of this slow speed is due to the route, but surely a train with a maximum speed of 90-100 mph, with an appropriate total amount of diesel power, would be the following.

  • Lighter in weight.
  • More efficient.
  • Emit less pollution.
  • Still capable of high speed on electrified lines.
  • Bi-mode and electric versions could run in pairs between Leeds and London.

LNER would probably save on track access charges and diesel fuel.

LNER To Other Places

Could LNER split and join in a similar way to other places?

  • Doncaster for Hull and Sheffield
  • Edinburgh for Aberdeen and Inverness
  • Newark for Lincoln and Nottingham
  • York for Middlesbrough and Scarborough.

It should be noted that many of the extended routes are quite short, so I suspect some train diagrams will be arranged, so that trains are only filled up with diesel overnight,

GWR

Great Western Railway are another First Group company and I’m sure some of their routes could benefit, from similar planning to that of Avanti West Coast.

Splitting and joining might take place at Reading, Swindon, Bristol and Swansea.

South Western Railway

South Western Railway will need to replace the three-car Class 159 trains to Exeter, that generally work in pairs with a total number of around 400 seats, in the next few years.

These could be replaced with a fleet of third-rail Hitachi trains of appropriate length.

  • Seven cars sating 420 passengers?
  • They would remove diesel trains from Waterloo station.
  • All South Western Railway Trains running between Waterloo and Basingstoke would be 100 mph trains.

I wonder, if in-cab digital signalling on the route, would increase the capacity? It is sorely needed!

Southeastern

Southeastern need bi-mode trains to run the promised service to Hastings.

  • Trains would need a third-rail capability.
  • Trains need to be capable of 140 mph for High Speed One.
  • Trains need to be able to travel the 25 miles between Ashford International and Ore stations.
  • Trains would preferably be battery-electric for working into St. Pancras International station.

Would the trains be made up from six twenty-metre cars, like the Class 395 trains?

The Simple All-Electric Train

The Modern Railways article, also says this about the ten all-electric AT-300 trains for Birmingham, Blackpool and Liverpool services.

The electric trains will be fully reliant on the overhead wire, with no diesel auxiliary engines or batteries.

It strikes me as strange, that Hitachi are throwing out one of their design criteria, which is the ability of the train to rescue itself, when the overhead wires fail.

In Do Class 800/801/802 Trains Use Batteries For Regenerative Braking?, I published this extract from this document on the Hitachi Rail web site.

The system can select the appropriate power source from either the main transformer or the GUs. Also, the size and weight of the system were minimized by designing the power supply converter to be able to work with both power sources. To ensure that the Class 800 and 801 are able to adapt to future changes in operating practices, they both have the same traction system and the rolling stock can be operated as either class by simply adding or removing GUs. On the Class 800, which is intended to run on both electrified and non-electrified track, each traction system has its own GU. On the other hand, the Class 801 is designed only for electrified lines and has one or two GUs depending on the length of the trainset (one GU for trainsets of five to nine cars, two GUs for trainsets of 10 to 12 cars). These GUs supply emergency traction power and auxiliary power in the event of a power outage on the catenary, and as an auxiliary power supply on non-electrified lines where the Class 801 is in service and pulled by a locomotive. This allows the Class 801 to operate on lines it would otherwise not be able to use and provides a backup in the event of a catenary power outage or other problem on the ground systems as well as non-electrified routes in loco-hauled mode.

This is a very comprehensive power system, with a backup in case of power or catenary failure.

So why does it look like Hitachi are throwing that capability out on the trains for Avanti West Coast.

There are several possibilities.

  • The reliability of the trains and the overhead wire is such, that the ability of a train to rescue itself is not needed.
  • The auxiliary generator has never been used for rescuing the train.
  • The West Coast Main Line is well-provided with Thunderbird locomotives for rescuing Pendelinos, as these trains have no auxiliary generator or batteries.
  • Removal of the excess weight of the auxiliary engine and batteries, enables the Hitachi AT-300 trains to match the performance of the Pendelinos, when they are using tilt.

Obviously, Hitachi have a lot of train performance statistics, from the what must be around a hundred trains in service.

It looks like Hitachi are creating a lightweight all-electric train, that has the performance or better of a Pendelino, that it achieves without using tilt.

  • No tilt means less weight and more interior space.
  • No auxiliary generator or batteries means less weight.
  • Wikipedia indicates, that Hitachi coaches are around 41 tonnes and Pendelino coaches are perhaps up to ten tonnes heavier.
  • Less weight means fast acceleration and deceleration.
  • Less weight means less electricity generated under regenerative braking.
  • Pendelinos use regenerative braking, through the catenary.
  • Will the new Hitachi trains do the same instead of the complex system they now use?

If the train fails and needs to be rescued, it uses the same Thunderbird system, that the Pendelinos use when they fail.

Will The New Hitachi Trains Be Less Costly To Run?

These trains will be lighter in weight than the Pendelinos and will not require the track to allow tilting.

Does this mean, that Avanti West Coast will pay lower track access charges for their new trains?

They should also pay less on a particular trip for the electricity, as the lighter trains will need less electricity to accelerate them to line speed.

Are Avanti West Coast Going To Keep The Fleets Apart?

Under a heading of Only South Of Preston, the Modern Railways article says this.

Unlike the current West Coast fleet, the Hitachi trains will not be able to tilt. Bid Director Caroline Donaldson told Modern Railways this will be compensated for by their improved acceleration and deceleration characteristics and that the operator is also working with Network Rail to look at opportunities to improve the linespeed for non-tilting trains.

The routes on which the Hitachi trains will operate have been chosen with the lack of tilt capability in mind, with this having the greatest impact north of Preston, where only Class 390 Pendelinos, which continue to make use of their tilting capability will be used.

Avanti West Coast have said that the Hitachi trains will run from London to Birmingham, Blackpool and Liverpool.

All of these places are on fully-electrified branches running West from the West Coast Main Line, so it looks like there will be separation.

Will The New Hitachi Trains Be Faster To Birmingham, Blackpool And Liverpool?

Using data from Real Time Trains, I find the following data about the current services.

  • Birmingham and Coventry is 19 miles and takes 20 minutes at an average speed of 57 mph
  • Blackpool and Preston is 16.5 miles and takes 21 minutes at an average speed of 47 mph
  • Liverpool and Runcorn is 3.15 miles and takes 15 minutes at an average speed of 52 mph

All the final legs when approaching the terminus seem to be at similar speeds, so I doubt there are much savings to be made away from the West Coast Main Line.

Most savings will be on the West Coast Main Line, where hopefully modern in-cab digital signalling will allow faster running at up to the design speed of both the Hitachi and Pendelino trains of 140 mph.

As an illustration of what might be possible, London to Liverpool takes two hours and thirteen minutes.

The distance is 203 miles, which means that including stops the average speed is 91.6 mph.

If the average speed could be raised to 100 mph, this would mean a journey time of two hours and two minutes.

As much of the journey between London and Liverpool is spent at 125 mph, which is the limit set by the signalling, raising that to 135 mph could bring substantial benefits.

To achieve the journey in two hours would require an overall average speed of 101.5 mph.

As the proportion of track on which faster speeds, than the current 125 mph increase over the next few years, I can see Hitachi’s lightweight all-electric expresses breaking the two hour barrier between London and Liverpool.

What About The Pendelinos And Digital Signalling?

The January 2020 Edition of Modern Railways also has an article entitled Pendolino Refurb Planned.

These improvements are mentioned.

  • Better standard class seats! (Hallelujah!)
  • Refreshed First Class.
  • Revamped shop.

Nothing is mentioned about any preparation for the installation of the equipment to enable faster running using digital in-cab signalling, when it is installed on the West Coast Main Line.

Surely, the trains will be updated to be ready to use digital signalling, as soon as they can.

Just as the new Hitachi trains will be able to take advantage of the digital signalling, when it is installed, the Pendellinos will be able to as well.

Looking at London and Glasgow, the distance is 400 miles and it takes four hours and thirty minutes.

This is an average speed of 89 mph, which compares well with the 91.6 mph between London and Liverpool.

Raise the average speed to 100 mph with the installation of digital in-cab signalling on the route, that will allow running at over 125 mph for long sections and the journey time will be around four hours.

This is a table of average speeds and journey times.

  • 100 mph – four hours
  • 105 mph – three hours and forty-eight minutes
  • 110 mph – three hours and thirty-eight minutes
  • 115 mph – three hours and twenty-eight minutes
  • 120 mph – three hours and twenty minutes
  • 125 mph – three hours and twelve minutes
  • 130 mph – three hours and four minutes

I think that I’m still young enough at 72 to be able to see Pendelinos running regularly between London and Glasgow in three hours twenty minutes.

The paragraph is from the Wikipedia entry for the Advanced Passenger Train.

The APT is acknowledged as a milestone in the development of the current generation of tilting high speed trains. 25 years later on an upgraded infrastructure the Class 390 Pendolinos now match the APT’s scheduled timings. The London to Glasgow route by APT (1980/81 timetable) was 4hrs 10min, the same time as the fastest Pendolino timing (December 2008 timetable). In 2006, on a one off non-stop run for charity, a Pendolino completed the Glasgow to London journey in 3hrs 55min, whereas the APT completed the opposite London to Glasgow journey in 3hrs 52min in 1984.

I think it’s a case of give the Pendelinos the modern digital in-cab signalling they need and let them see what they can do.

It is also possible to give an estimate for a possible time to and from Manchester.

An average speed of 120 mph on the route would deliver a time of under one hour and forty minutes.

Is it possible? I suspect someone is working on it!

Conclusion

I certainly think, that Avanti West Coast, Hitachi and Network Rail, have been seriously thinking how to maximise capacity and speed on the West Coast Main Line.

I also think, that they have an ultimate objective to make Avanti West Coast an operator, that only uses diesel fuel in an emergency.

Does One Of Baldrick’s Descendents Work For Avanti West Coast?

I have been looking at the problems of maximising traffic and reducing journey times on the West Coast Main Line to the North of Crewe.

I think that what Avanti West Coast intend to do has a touch of the Baldricks about it.

Trains that go North from Crewe include the following Avanti West Coast services.

  • Blackpool, which branches off at Preston.
  • Glasgow, which goes up the West Coast Main Line via Preston, Lancaster, Oxenholme and Carlisle.
  • Liverpool, which branches off at Weaver Junction, between Crewe and Warrington.
  • Manchester, which branches off at Crewe.

I find it interesting that according to Wikipedia, Avanti West Coast will be running their new Hitachi electric trains to Blackpool and Liverpool, but not Manchester.

Could it be that as these trains will be sharing tracks to the North of Crewe in the future with High Speed Two services to Preston, Carlisle and Scotland, that these trains will be built to have the same operating speed on the West Coast Main Line, as the classic-compatible High Speed Two trains, that will serve the route?

The Manchester Branch is slower, so will remain 125 mph Pendelino territory.

The Number Of Electric Trains Ordered

Doing a rough estimate< I reckon the following.

  • One train per hour (tph) to Liverpool needs five 125 mph Pendelinos.
  • One tph to Blackpool needs six 125 mph Pendelinos.
  • .Two tph to Liverpool needs ten 125 mph Pendelinos.
  • If the new Hitachi trains, are capable of 140 mph, I reckon two tph to Liverpool might need eight 140 mph trains.

The order of new Hitachi trains is not large enough to run both Blackpool and Liverpool services.

Will The New Hitachi Trains Be Used On London and Liverpool?

Consider.

  • It would probably the best policy to run each route with one class of train.
  • A two tph London and Liverpool service is much needed.
  • Running the new Hitachi trains on London and Liverpool, would release extra trains for London and Blackpool and London and Birmingham.
  • Two tph to Liverpool needs eight 125 mph Pendelinos or eight 140 mph Hitachi trains.

But it would also mean installing ERTMS signalling on the London and Liverpool route to enable 140 mph running.

It does appear that ten new Hitachi trains, able to run at 140 mph could service the London and Liverpool route and release five Pendelinos for other routes.

Could The Pendelinos Run At 140 mph?

They were designed for this speed, as were the InterCity 225 trains and only don’t run at this speed because of the lack of digital signalling on the West Coast Main Line.

The Wikipedia entry for the Class 390 Pendelino train says this about the speed of the train.

The Class 390 Pendolino is one of the fastest domestic electric multiple units operating in Britain, with a design speed of 140 mph (225 km/h); however, limitations to track signalling systems restrict the trains to a maximum speed of 125 mph (200 km/h) in service. In September 2006, the Pendolino set a new speed record, completing the 401 mi (645 km) length of the West Coast Main Line from Glasgow Central to London Euston in 3 hours, 55 minutes.

Perhaps it is time to unleash the Pendelinos?

Could the planned refurbishment of the Pendelinos install the required equipment, allow the trains to run using digital signalling at 140 mph?

What Is The Cunning Plan?

These are the possible objectives of adding the extra ten trains.

  • One tph between London and Glasgow in around four hours.
  • Two tph between London and Liverpool in around two hours.

Would this be one possible way to achieve these objectives?

  • Install digital signalling on the West Coast Main Line to allow 140 mph in places, where the track allows.
  • Improve the track of the West Coast Main Line, where necessary.
  • Run new Hitachi trains between London and Liverpool.
  • Release the current Pendelinos to other routes.
  • Upgrade the Pendelinos with digital signalling to allow 140 mph running, where possible.
  • Run 140 mph Pendelinos between London and Blackpool, Edinburgh and Glasgow.

The real plan will probably be a lot better and more comprehensive, but it does show how the two objectives can be met.

Conclusion

To improve services between London and Birmingham, Blackpool, Liverpool and Scotland, appears to need the following.

  • Ten new Hitachi trains.
  • Full digital signalling on the West Coast Main Line.
  • Track improvements on the West Coast Main Line
  • Upgrading of the Pendelinos to allow 140 mph running.

This should reduce London and Glasgow to around four hours and London and Liverpool to around two hours.

TransPennine Express’s New Liverpool Lime Street And Glasgow Central Service

Transpennine Express are introducing a new service between Liverpool Lime Street and Glasgow Central stations at the December 2019 timetable change.

So I examined the service for the the 21st January, 2020.

  • There are three Northbound trains at 08:12, 12:12 and 16:12.
  • There are three Southbound trains at 07:45, 11:44 and 16:29
  • Journey times vary between three hours and 17 minutes and three hours and 47 minutes.
  • Trains appear to always stop at Wigan North Western, Preston, Penrith North Lakes and Carlisle.
  • Selective services call at other stations including Lancaster and St. Helens Central.

As passengers can always travel the route with a change at Preston, it is a useful start. It should also be born in mind that there are currently, two trains per hour (tph) between Glasgow Central and Preston stations, so the route with a change at Preston can be quicker than waiting for a direct train.

If you look at the Transpennine service between Manchester Airport and Glasgow Central stations, it appears that there are gaps in the hourly service at 08:00, 12:00 and 16:00.

These gaps have now been filled with Liverpool services.

Current and Future Trains Between Liverpool or Manchester and Glssgow or Edinburgh

The current service is run by nine Class 350 trains, which includes the following.

  • One tph between Between Manchester Airport and Glasgow Central, with three services missing.
  • One train every two hours between Manchester Airport and Edinburgh.

The service from the December 2019 change will at some point be run by twelve Class 397 trains.

It will add three trains per day between Liverpool Lime Street and Glasgow Central, which will give an hourly TranPennine service between Glasgow Central and Preston.

I estimate that the new service will require two more trains, which is incorporated in the larger fleet size.

Timings Between Preston And Glasgow

If you look at the limitings between Preston and Glasgow, you find the following.

  • Virgin’s Class 390 trains take between two hours 21 minutes and two hours 34 minutes.
  • The new Liverpool service is timetabled to take two hours 53 minutes.

As the current Class 350 trains are only 110 mph trains, this is the explanation.

But the new Class 397 trains are 125 mph trains and can probably match the times set by Virgin.

So expect to see some timing reductions on TransPennine’s routes on the West Coast Main Line.

Will Services Between Liverpool And Manchester and Glasgow Split And Join At Preston?

TransPennine Express are meeting their franchise obligations, by providing three trains per day between Liverpool ad Glasgow, but could they do better by splitting and joining services at Preston.

  • Going North, a service from Manchester Airport and one from Liverpool would join at Preston, before proceeding to Glasgow as a ten-car train.
  • Coming South, a pair of trains from Glasgow, would split at Preston, with one train going to Liverpool and the other to Manchester Airport.

Obviously, the trains would need to be able to split and join in a minute or so, but it would open up the possibility of an hourly service from both Liverpool and Manchester to Glasgow.

Liverpool And Manchester To Edinburgh

After the December 2019 timetable change, TransPennine’s Liverpool and Newcastle service will be extend to Edinburgh, giving Liverpool a direct service to \Edinburgh and Manchester, a second service to Edinburgh.

Timings by the various routes will be.

  • Liverpool and Edinburgh via Manchester, Leeds and York – Four hours 28 minutes – Hourly
  • Manchester Piccadilly and Edinburgh via Preston and Carstairs – Three hours 10 minutes – Two hourly
  • Manchester Victoria  and Edinburgh via Leeds and York – Three hours 52 minutes – Hourly

These times compare well with the four hours drive predicted on the Internet.

Conclusion

Connections between Northern England and the Central Belt of Scotland will improve greatly after the December 2019 timetable change.

New trains on these routes will also mean faster services, where they run on the East and |West Coast Main Lines.

More trains will also increase frequency.

On The Caledonian Sleeper To Glasgow

I started this post on the Caledonian Sleeper to Glasgow.

It’s one of the new Mark 5 trains and they are a great improvement, although one Scottish hard man, preferred the old Mark 3s.

Out of Euston we were doing 80 mph and the ride in the Lounge Car is good. At least up to the standard of a Greater Anglia Mark 3, which are some of the best!

These are some pictures of my train.

I don’t think I could fault the train.

But the service was rather sub-standard, due to a strike and I got a partial refund.

Row Erupts Over Decision To Scrap Glasgow Rail Link For Transport Pods

The title of this post is the same as that of this article on Global Construction Review.

This is the first two paragraphs.

A row has broken out over a decision to cancel a direct rail link between Glasgow Airport and the town of Paisely, just east of Glasgow, in favour of exploring a self-driving transportation pod system.

The direct rail link was announced as part of a £1.1bn investment in the Glasgow City Region deal agreed in 2014 and was expected to be operational by 2025.

I am not sure, which system I prefer, but then I’m a rather different type of airport traveller.

  • I generally travel alone.
  • I rarely have anything more than a man-bag and a small hold-all.
  • I want convenience and can easily walk up to a kilometre with my hold-all.
  • I only fly Ryanair as an airline of last resort.

But what annoys me most, is if to get to the Airport, I have to scratch around buying a ticket for the link from the station to the Airport.

At all London Airports, except Luton, you buy a ticket to the airport station or use a contactless card.

Luton is introducing an automated shuttle between the airport and Luton Airport Parkway station and if it is not free, I’ll never use the airport.

A Tram-Train Rail Link

Edinburgh and Manchester Airports have tram links between the Airport and the City Centre, so I can’t see any problems with a tram-train link, that instead of dropping you on the street in the City Centre, as a tram would do, drops you in a railway station.

The way Manchester is thinking about tram-trains, I wouldn’t be surprised to see them at Manchester Airport.

Based on what I have seen in Sheffield, I don’t believe there would be any serious problems developing a tram-train link to Glasgow Airport..

However, these could be issues.

  • Is there enough spare capacity on the Inverclyde Line?
  • The tram-train link would go to Paisley Gilmore Street and Glasgow Central stations, but what if your local train service to Glasgow goes to Glasgow Queen Street station.

Would many people still use their cars to get to the Airport?

A Pod System

I wrote about the proposed pod system for Glasgow Airport in An Innovative Scheme For A Rail Link To Glasgow Airport.

It has its plus points, but I worry that getting the right number of pods to provide a good service might be tricky.

Would many people still use their cars to get to the Airport?

IThe Connection In Glasgow

Glasgow’s problem is that both these links connect into the centre of Glasgow at Glasgow Central station.

So if your connection to Glasgow comes into Glasgow Queen Street station, you will have to hump your bags across the City Centre.

A plan has existed for years to create Crossrail Glasgow, which would make matters easier.

But nothing has so far been decided.

Conclusion

There is no point in building any form of link to Glasgow Airport, unless Crossrail Glasgow is built.

Otherwise, passengers with an indirect route to Glasgow Central station will still drive or avoid the airport entirely.

Walking Between Glasgow Queen Street And Central Stations

I arranged my trip through Glasgow so that I arrived in Glasgow Queen Street station around lunchtime, so that I could have lunch at a restaurant on my way to Glasgow Central station.

I took the side entrance to Queen Street station and walked to West Nile Street, where I had lunch in Gourmet Burger Kitchen.

From the restaurant, I continued down West Nile Street, before turning right for Glasgow Central station.

This Google Map shows the two stations and the area in between.

There’s probably a cafe or restaurant to suit everybody on the walking route.

Walking the way I did was slightly down hill and parts were in pedestrianised streets.

I know Glasgow’s two main stations fairly well, but there should be a signposted walking route.

From Glasgow To Carlisle In A Class 350 Train

TransPennine Express are replacing their Class 350 trains with new Class 397 trains.

So coming down from Glasgow to Carlisle, I took one of the Class 350 trains to see why they are being replaced.

The train that I rode, had been spruced up with the new livery.

The new Class 397 train has the following advantages over the Class 350 train.

  • It will be a 125 mph train rather than a 110 mph train.
  • It will have power sockets, wi-fi and possibly 4G connectivity
  • It will be five-cars instead of four-cars.

Will there be any other passenger features like a buffet?
