The Anonymous Widower

A First Visualisation Of Headbolt Lane Station

This visualisation of the proposed Headbolt Lane station in Kirkby has appeared on several web sites.

Wikipedia also says that the station will have one platform and as there is a Class 777 train on the left hand side of what I take to be the station building, I would assume that is the platform.

It looks an interesting station layout with a wide concourse with trains on one side and buses on the other.

I can’t work out from the image, if there is a long shelter alongside the train, as one sees on some tram stops. But if it was felt necessary one could surely be fitted to give passengers some covering in inclement weather.

As the station also features five-hundred parking spaces, these must be arranged around the station on this side of the railway, which is currently just a single track.

The Plans On Rail Future

This page on the Rail Future web site is entitled A Station Back In Skelmersdale and it indicates the following.

  • A map shows a spur, which is connected to the Kirkby and Wigan Line, by a large triangular junction between Rainford and Upholland stations, running North to Skelmersdale.
  • Services of two tph between Liverpool and Skelmersdale and an hourly service between Manchester and Skelmersdale are proposed.
  • Rainford station would appear to exchange a direct link to Manchester for a direct link to Liverpool. But then Rainford is in Merseyside and Upholland and Skelmersdale are in Lancashire.

With these proposals the junction and the spur would only need to be single-track, with Skelmersdale station only needing a single-platform.

Could the following simplifications also be done?

  • Upholland and Rainford stations become single platform stations
  • The track between the two stations is mothballed or even removed.
  • There would only be a single track between both stations and Skelmersdale station.

There’s certainly scope to save money on construction and maintenance.

Could this single track and platform design be the reason, why Headbolt Lane station only has a single platform?

Consider.

  • The current Kirkby station, handles four tph to and from Liverpool City Centre on a single platform.
  • The line becomes double-track to the East of Fazakerley station.
  • I suspect double-track is needed to allow 4 tph

I suspect Headbolt Lane station could handle four tph to and from Liverpool, but there may need to be some double-track between Kirkby and Headbolt Lane stations.

I also estimate that to travel the return journey on the approximately eight miles between Headbolt Land and Skelmersdale station will take about thirty minutes.

Would this mean that it were possible to create a timetable, which allowed four tph between Liverpool and Headbolt Lane stations and two tph between Headbolt Lane and Skelmersdale stations?

  • The single platform would be bi-directional.
  • Two tph out of four arriving at Headbolt Lane station would reverse and go back to Liverpool.
  • The other two tph would continue to Skelmersdale.
  • The two tph returning from Skelmersdale would continue to Liverpool.

It would be one for the Busby Berkeley of train time-tabling.

The alternative of running four tph between Liverpool and Skelmersdale would need the following.

  • Full double-tracking between Fazakerley and Skelmersdale stations.
  • Two platform stations at Kirkby, Headbolt Lane and Rainford, which would need step-free bridges.

It would be a much more expensive scheme.

How Much New Electrification Would Be Needed?

Given the politics of third-rail electrification, I suspect the scheme will use as little as possible.

If the battery-equipped Class 777 trains can run the return journey between Kirkby and Skelmersdale stations, then all track to the East of Kirkby station could be without electrification.

This would probably also mean that the current power supply wouldn’t need to be upgraded to cope with additional electrification.

Could There Be A Two tph Service Between Skelmersdale And Manchester?

I don’t think a single-track line between Upholland and Skelmersdale would rule this out, but having two two tph services might need a second platform at Skelmersdale station.

On the other hand, the Manchester and Liverpool services could be timed to allow a cross-platform interchange at Skelmersdale.

This would mean that someone wanting to go between say Sandhills and Bolton would go direct with a quick change at Skelmersdale.

Could There Be Through Running Between Manchester And Kirkby?

Four tph between Liverpool and Headbolt Lane station with two tph extending to Skelmersdale, running through the single-platform stations at Kirkby, Headbolt Lane and Rainford, would probably make the current Manchester and Kirkby service difficult, if not impossible.

But as the change at Kirkby will be replaced with one at Skelmersdale, it would be more of an inconvenience than a disaster.

In addition, if two tph were to be run between Manchester and Skelmersdale and the trains were timetabled to meet at Skelmersdale, this would effectively be a pseudo-through service.

A single track could be left between Upholland and Rainford for engineering trains and possibly the occasional freight train.

Strategic Car Parking

Consider.

  • The new Headbolt Lane station, is going to be provided with five hundred car-parking spaces.
  • The new Skelmersdale station will probably have adequate provision.
  • At the present time, Rainford and Upholland stations don’t appear to have any parking.

I would suggest, that a good look is taken at car and bicycle parking at all stations to the East of Headbolt Lane station.

Conclusion

It appears to be a scheme, that has been designed to keep costs to a minimum.

But that probably means, it is more likely to get built!

I also like the concept of a large station concourse alongside a single platform and track, which will probably be without electrification. It should be very safe too!

It is strange, that I’ve not seen that layout before either in the UK or on the many railways, that I’ve used abroad.

New MerseyRail ‘Connected’ Trains

The title of this post, is the same as that of this article on Rail Engineer.

It is an article that should be read, by anybody with an interest in either Merseyrail’s trains or modern urban rail networks in general. As Stadler, will be providing a fleet of trains for the Tyne and Wear Metro, I suspect a lot of the points made in the article can be expected to have parallels on that network as well.

What About The Signalling?

The article talks about the management of the signalling, but it says little about signalling in the future, although it does say that Merseyrail will be covered by a very high capacity digital network.

London’s Digital Signalling Revolution

In London, there are four tunnelled routes, that in a few years time will be running under full digital signalling.

  • Crossrail
  • East London Line
  • Northern and City Line
  • Thameslink

Note.

  1. Thameslink is already running upwards of twenty trains per hour (tph) using digital ERTMS signalling.
  2. Crossrail will be running 24 tph using digital ERTMS signalling.
  3. The East London Line currently handles 16 tph and will soon be handling 20 tph.
  4. The Northern and City Line will be going to digital ERTMS signalling, when it is applied to the Southern end of the East Coast Main Line.
  5. , In addition to the Circle, District, Jubilee, Metropolitan, Northern and Victoria Lines of the London Underground have digital signalling.
  6. Dear old Vicky is actually running 36 tph between two-platform stations at Brixton and Walthamstow Central.
  7. I wouldn’t bet against Vicky running the magic 40 tph, to become the most frequency line in the world.

All of these London systems, have one great advantage. In the tunnelled sections of the routes, there is generally only one class of fully digitally-equipped train, which must make system design and implementation easier.

Liverpool’s Digital Signalling Revolution

Consider.

  • As the article says, Merseyrail now has a world-class high-capacity digital network, that is accessible by all of its trains.
  • It has ordered 52 new Class 777 trains and has options for another sixty.
  • There are proposals to extend the Merseyrail network to Manchester, Preston, Skelmersdale, Warrington, Wigan and Wrexham.
  • The Northern Line runs at a frequency of 12 tph.
  • The Wirral Line runs at a frequency of 14 tph.
  • The loop Line has recently been relaid, so is probably high-quality track.

Compared to London’s tunnelled routes, the Northern and Wirral Lines are not handling a large number of trains.

But Liverpool now has a digital network to support the signalling and trains that could be upgraded to use it are arriving.

I wouldn’t be surprised to find that the maximum train frequency on Merseyrail is at least twenty tph or one train every three minutes.

What Would Twenty tph Do For The Wirral Line?

Currently, the following destinations are served by the Wirral Line and the services use the Loop under Liverpool City Centre.

Note.

  1. The current frequency around the Loop is 14 tph.
  2. Merseyrail is proposing to extend the Ellesmere Port service to Helsby, using battery-equipped Class 777 trains
  3. There is also an hourly service from Bidston to Wrexham Central in the Borderlands Line.
  4. I can see no technical reason why, the Bidston and Wrexham service could not be run using battery-equipped Class 777 trains and terminating in the Loop.

Surely, the ultimate twenty tph service on the Wirral Line would be as follows.

  • Chester – Four tph
  • Helsby via Ellesmere Port – Four tph
  • New Brighton – Four tph
  • West Kirby – Four tph
  • Wrexham Central – Four tph

All twenty tph would terminate in the Loop under Liverpool City Centre.

What Would Twenty tph Do For The Northern Line?

Currently, the following Northern destinations are served by the Northern Line.

And these Southern destinations are served.

Note.

  1. The current frequency, through the central section is 12 tph.
  2. There is a proposal, that I wrote about in Liverpool’s Forgotten Tunnel for the trains terminating at Liverpool Central station to use the Wapping Tunnel to connect to the City Line.
  3. There is a proposal to extend the Ormskirk service to Preston, using battery-equipped Class 777 trains.
  4. There is a proposal to extend the Kirkby service to Headbolt Lane and Skelmersdale, using battery-equipped Class 777 trains.
  5. There must also be a possibility of a service that extends the Kirkby service to Wigan Wallgate, using battery-equipped Class 777 trains.

The service des appear to be biased towards the Northern end, with more possibilities there for extra trains than in the South.

This is why the plan to expand to the East through the Wapping Tunnel has evolved, as it gives the following possible destinations.

  • Manchester Oxford Road
  • Warrington Bank Quay
  • Warrington Central
  • Wigan North Western

Note.

  1. All destinations are currently served from Liverpool Lime Street by Northern.
  2. There must also be the possibility of a direct service to Liverpool Airport.
  3. There must also be the possibility of a service on the Canada Dock Branch to Bootle.

I can envisage between 12 and 16 tph through the Wapping Tunnel, which with the four tph to Hunts Cross could mean 16 to 20 tph on the Northern Line.

Conclusion

It would appear that a very frequent system can be developed on Merseyside, if frequencies common in London can be achieved.

The Big Metro Fleet Upgrade That Could Make It ‘Easy’ To Finally Extend Train Services To New Areas

The title of this post, is the same as that of this article on the Newcastle Chronicle.

This is the first paragraph.

Every train in Metro’s new fleet will be capable of running via an on-board battery, reducing the chance of major shutdowns and making it much cheaper to extend the network.

The fact that it is technically possible, is not a surprise as Stadler’s Class 777 trains for Merseyrail will be using battery power to extend routes. I would be very surprised if the new Tyne and Wear Metro trains and those for Merseyrail, didn’t have a lot of design in common.

But what is surprising, is that the Tyne and Wear Metro’s whole fleet will be fitted with batteries. This must be the first time in the UK, that a whole fleet of trains has been said to have batteries.

The Merseyrail trains will also have a dual voltage capability and will be able to be modified for running on 25 KVAC overhead electrification, as well as 750 VDC third-rail electrification.

Will the Tyne and Wear trains be able to use 25 KVAC electrification? It could be useful in some places on the network and I’m sure, if there was a financial case for a service using existing 25 KVAC electrification, then some trains would be modified accordingly.

A Quick Comparison

This is a quick comparison between Merseyrail’s Class 777 trains and the Tyne and Wear Metro’s new trains.

  • Cars – 777 – 4 – T&W – 5
  • Operating Speed – 777 – 75 mph – T&W – 50 mph
  • Capacity – 484 – T&W – 600
  • Capacity Per Car – 121 – T&W – 125
  • In Service – 2022 (?) – T&W – 2024

They are not that different and it looks like the Tyne and Wear trains will be built after the Merseyrail trains.

Charging Battery Trains

In Sparking A Revolution, I talked about Hitachi’s plans to develop battery versions of their Class 800 trains.

The article also gives the specification of a Hitachi battery train.

  • Range – 55-65 miles
  • Performance – 90-100 mph
  • Recharge – 10 minutes when static
  • Routes – Suburban near electrified lines
  • Battery Life – 8-10 years

These figures are credited to Hitachi.

Methods Of Charging

I can envisage two main methods of changing battery trains.

  • Static charging in a station, depot or siding.
  • Dynamic charging, whilst the train is on the move.

I am not covering other possible methods like battery swapping in this post.

Static Charging

Hitachi only mention static charging in their specification and they give a charge time of ten minutes.

This is a very convenient time, when you consider quite a few trains take around 10-15 minutes to turn round at a terminus.

Two companies have stated that they have products that can charge battery trains in around this time.

  • Vivarail offers a system based on well-proven third-rail electrification technology.
  • Furrer and Frey offers a system based on overhead electrification technology.

I suspect that other companies are developing systems.

Dynamic Charging

With dynamic charging, the batteries are charged as the trains run along standard electrified routes.

In the UK, this means one of two systems.

  • 750 VDC third rail electrification
  • 25 KVAC overhead electrification

Both systems can be used to charge the batteries.

Note that in the BEMU Trial in 2015, the Class 379 train used for the trial charged the batteries from the 25 KVAC overhead electrification.

A Mixture Of Dynamic And Static Charging

Many routes will be handled by a mixture of both methods.

As an example London Paddington and Cheltenham is electrified except for the 42 miles between Swindon and Cheltenham.

A round trip between London Paddington and Cheltenham could be handled as follows.

  • London Paddington to Swindon using electrification – Dynamic charging battery at the same time!
  • Swindon to Cheltenham using battery power
  • Turnround at Cheltenham – Static charging battery at the same time!
  • Cheltenham to Swindon using battery power
  • Swindon to London Paddington using electrification

Note the following.

  1. Two legs of the round-trip are run using electrification power.
  2. Two legs of the round-trip are run using battery power.
  3. There is one dynamic charge and one static charge of the batteries.

No diesel power would be used on the journey and I suspect journey times would be identical to the current timetable.

I suspect that many routes run by battery electric trains will employ a mixture of both dynamic and static charging.

Here’s a few examples.

  • London Kings Cross and Lincoln
  • London Kings Cross and Harrogate
  • London St Pancras and Melton Mowbray
  • London Euston and Chester
  • London Paddington and Bedwyn

There are probably many more.

Intermediate Charging On A Long Route

South Western Railway has a fleet that is nearly all-electric.

But they do have forty diesel trains, which are mainly used for services between London Waterloo and Exeter.

These don’t fit with any decarbonising strategy.

There is also the problem that the route between London Waterloo and Exeter, is only electrified as far as Basingstoke, leaving a long 124 miles of route without electrification.

This means that a battery train needs to charge the batteries at least twice en route.

Charging At A Longer Stop

The obvious approach to providing en route charging would be to perform a ten minute stop, where the batteries are fast charged.

Looking at Real Time Trains, the stop at Salisbury is often five minutes or more, as trains can join and split and change crews at the station.

But two stops like this could slow the train by fifteen minutes or so.

Charging At A An Electrification Island

On the section of the route, West of Salisbury, there are a series of fairly close-together stations.

  • Tisbury – 7 miles
  • Gillingham – 16 miles
  • Templecombe – 18 miles
  • Sherborne – 23 miles
  • Yeovil Junction – 39 miles
  • Crewkerne – 48 miles
  • Axminster – 61 miles

Note,

The distances are from Salisbury.

  1. Much of this nearly ninety mile section of the West of England Line between Salisbury and Exeter is single track.
  2. The Heart of Wessex Line between Westbury and Weymouth crosses at Yeovil Junction.
  3. There are three sections of double track and four passing loops.
  4. There is a passing loop at Axminster.

It strikes me that the optimal way of charging battery trains on this secondary route might be to electrify both the West of England and Heart of Wessex Lines around Yeovil Junction station.

The power for the electrification island, could come from local renewable sources, as proposed by Riding Sunbeams.

Distances from Yeovil Junction station are.

  • Bath Spa – 50 miles
  • Castle Cary – 12 miles
  • Exeter St. Davids – 49 miles
  • Salisbury – 39 miles
  • Weymouth – 30 miles

With a battery-electric train with a 55-65 mile range, as proposed in Hitachi’s draft specification, SWR’s London Waterloo and Exeter service would certainly be possible. Charging would be at Salisbury and in the Yeovil area.

On Summer Saturdays, SWR also run a London Waterloo and Weymouth service via Salisbury and Yeovil Junction. This would appear to be within the range of a battery-electric train.

As Weymouth is electrified with third-rail, I suspect that arranging charging of a battery-electric train at the station, will not be an impossible task.

The other service through the area is Great Western Railway‘s service between Gloucester and Weymouth, that runs every two hours.

It would appear that in some point in the future, it will be possible to run this service using a Hitachi battery-electric train.

Third-Rail Or Overhead?

The previous example of an electrification island would probably use 750 VDC third-rail electrification, but there is no reason, why 25 KVAC overhead electrification couldn’t be used.

Note that these trains have been talked about as possibilities for running under battery power.

  • Greater Anglia’s Class 379 trains, built by Bombardier
  • Greater Anglia’s Class 755 trains, built by Stadler.
  • Merseyrail’s Class 777 trains, built by Stadler.
  • Scotrail’s Class 385 trains, built my Hitachi
  • Several companies’ Class 800 trains, built by Hitachi
  • Suthern’s Class 377 trains, built by Bombardier

All the manufacturers named have experience of both dual-voltage trains and battery operation.

I would suspect that any future battery-electric trains in the UK will be built to work on both of our electrification systems.

When talking about battery-electric trains, 750 VDC third-rail electrification may have advantages.

  • It can be easily powered by local renewable sources, as Riding Sunbeams are proposing.
  • It is compatible with Vivarail’s Fast-Charge system.
  • Connection and disconnection is totally automatic and has been since Southern Railway started using third-rail electrification.
  • Is is more affordable and less disruptive to install?
  • Third-rail electrification can be installed in visually-sensitive areas with less objections.

Developments in third-rail technology will improve safety, by only switching the power on, when a train is connected.

More Electrification Islands

These are a few examples of where an electrification island could enable a battery-electric train to decarbonise a service.

London Euston and Holyhead

In Are Hitachi Designing the Ultimate Battery Train?, I looked at running Hitachi’s proposed battery-electric trains between London Euston and Holyhead.

I proposed electrifying the fourteen miles between Rhyl and Llandudno Junction stations, which would leave two sections of the route between London Euston and Holyhead without electrification.

  • Rhyl and Crewe is fifty-one miles.
  • Llandudno Junction and Holyhead is forty-one miles.

Both sections should be within the battery range of Hitachi’s proposed battery-electric trains, with their 55-65 mile range.

The following should be noted.

  • The time between arriving at Rhyl station and leaving Llandudno Junction station is nineteen minutes. This should be time enough to charge the batteries.
  • Either 25 KVAC overhead or 750 VDC third-rail electrification could be used.
  • There could be arguments for third-rail, as the weather can be severe.
  • The railway is squeezed between the sea and the M55 Expressway and large numbers of caravans.

The performance of the new trains will be such, that they should be able to run between London Euston and Holyhead in a similar time. Using High Speed Two could reduce this to just under three hours.

Edinburgh And Aberdeen

I’m sure Scotland would like to electrify between Edinburgh and Aberdeen.

But it would be a difficult project due to the number of bridges on the route.

Distances from Edinburgh are as follows.

  • Leuchars – 50 miles
  • Dundee – 59 miles
  • Arbroath – 76 miles
  • Montrose – 90 miles
  • Stonehaven – 114 miles
  • Aberdeen – 130 miles

A quick look at these distances indicate that Hitachi’s proposed battery-electric trains with a 55-65 mile range could cover the following sections.

  • Edinburgh and Dundee – 59 miles
  • Arbroath and Aberdeen – 56 miles

Would it be possible to electrify  the seventeen miles between Dundee and Arbroath?

I have just flown my helicopter along the route and observed the following.

  • Dundee station is new and appears to be cleared for overhead wires.
  • Many of the bridges in Dundee are new and likely to be cleared for overhead wires.
  • There is a level crossing at Broughty Ferry station.
  • Much of the route between Broughty Ferry and Arbroath stations is on the landward side of golf links, with numerous level crossings.
  • Between Arbroath and Montrose stations, the route appears to be running through farmland using gentle curves.
  • There is a single track bridge across the River South Esk to the South of Montrose station.
  • According to Wikipedia, the operating speed is 100 mph.

Montrose might be a better Northern end to the electrification.

  • It has a North-facing bay platform, that could be used for service recovery and for charging trains turning back to Aberdeen.
  • Montrose and Aberdeen is only forty miles.
  • It might be possible to run the service between Montrose and Inverurie, which is just 57 miles on battery power.

The problem would be electrifying the bridge.

Operationally, I can see trains running like this between Edinburgh and Aberdeen.

  • Trains would leave the electrification, just to the North of Edinburgh with a full battery.
  • Battery power would be used over the Forth Bridge and through Fife and over the Tay Bridge to Dundee.
  • Electrification would take the train to Arbroath and possibly on to Montrose. The battery would also be charged on this section.
  • Battery power would take trains all the way to Aberdeen.

Trains would change between battery and electrification in Dundee and Arbroath or Montrose stations.

My one question, is would it be a good idea to electrify through Aberdeen, so that trains returning South could be charged?

I believe that four or five-car versions of Hitachi’s proposed battery-electric trains would be able to run the route.

Glasgow And Aberdeen

This builds on the work that would be done to enable battery-electric trains go between Edinburgh and Aberdeen.

The route between Glasgow and Dundee is partially-electrified with only a forty-nine mile section between Dundee and Dunblane without wires.

I believe that four or five-car versions of Hitachi’s proposed battery-electric trains would be able to run the route.

 

To Be Continued…

 

Conclusion

I don’t think it will be a problem to provide an affordable charging infrastructure for battery trains.

I also think, that innovation is the key, as Vivarail have already shown.

Batteries On Class 777 Trains

In this article on Railway Gazette, which is entitled Merseyrail Class 777 arrives in Liverpool, there is this sentence.

There is space under one vehicle to house a battery weighing up to 5 tonnes within the axleload limit.

This matter-of-fact sentence, draws me to the conclusion, that these trains have been designed from the start to allow future battery operation.

Batteries are not an add-on squeezed into a design with great difficulty.

Battery Capacity

Energy densities of 60 Wh/Kg or 135 Wh/litre are claimed by Swiss battery manufacturer; Leclanche.

This means that a five tonne battery would hold 300 kWh.

Note that Vivarail find space for 424 kWh in the two-car Class 230 train, I wrote about in Battery Class 230 Train Demonstration At Bo’ness And Kinneil Railway, so it would appear that Stadler aren’t being over ambitious.

Kinetic Energy Of A Full Class 777 Train

The weight of a full Class 777 train is calculated as follows.

  • Basic empty weight – 99 tonnes
  • Battery weight – 5 tonnes
  • 484 passengers at 80 Kg – 38.72 tonnes

Which gives a total weight of 143.72 tonnes.

Intriguingly, the weight of a current Class 507 train is 104.5 tonnes, which is 500 Kg more than an empty Class 777 train with a battery!

If these weights are correct, I suspect Stadler have used some very clever lightweight design techniques.

For various speeds, using Omni’s Kinetic Energy Calculator, this weight gives.

  • 30 mph – 3.6 kWh
  • 40 mph – 6.4 kWh
  • 50 mph – 10.0 kWh
  • 60 mph – 14.4 kWh
  • 70 mph – 19.5 kWh
  • 75 mph – 22.4 kWh

Note.

  1. The average speed between Bidston and Wrexham General stations on the Borderlands Line is under 30 mph
  2. The operating speed on the Wirral Line is 70 mph
  3. The operating speed on the Northern Line is 60 mph
  4. The maximum speed of the trains is 75 mph.

Every time I do these calculations, I’m surprised at how low the kinetic energy of a train seems to be.

How Small Is A Small Battery?

One battery doesn’t seem enough, for a train designed with all the ingenuity of a product with quality and precision, that is designed to out-perform all other trains.

This is another paragraph from the Railway Gazette article.

According to Merseytravel, ‘we want to be able to prove the concept that we could run beyond the third rail’. By storing recovered braking energy, the batteries would help to reduce power demand and the resulting greenhouse gas emissions. All of the Class 777s will be fitted with small batteries to allow independent movement around workshop and maintenance facilities.

I am not quite sure what this means.

It would seem strange to have two independent battery systems in one train.

I think it is more likely, that the smaller battery can be considered the primary battery of the train.

  • After all in the depot, it looks after the train’s power requirement.
  • Does it also handle all the regenerative braking energy?
  • Is it used as a secondary power supply, if say the power is low from the electrification?
  • Could it be used to move the train to the next station for passenger evacuation in the event of a power failure?

I wonder if the power system is a bit like the average battery-powered device like a lap-top computer, smart phone or hybrid car.

  • The electrification and the regenerative braking charges the battery.
  • The battery provides the traction and hotel power for the train.

When the five tonne battery is fitted, does the train’s control system move power between the two batteries to drive the train in the most efficient manner?

I’ll return to factors that define the size of the small battery.

The small battery must be big enough for these purposes.

  • Handling regenerative braking at the operating speed.
  • Recovering a full train to the next station.
  • Keeping a train’s systems running, during power supply problems.
  • Moving a train around a depot

As the lines leading to depots are electrified, the train can probably enter a depot with a battery fairly well-charged.

As the new Class 777 trains have a maximum operating speed of 75 mph, I would suspect that the small battery must be able to handle the regenerative braking from 75 mph, which my calculations show is 22.4 kWh with a full train. Let’s call it 30 kWh to have a reserve.

Using Leclanche’s figures, a 30 kWh battery would weigh 500 Kg and have a volume of just under a quarter of a cubic metre (0.222 cubic metre to be exact!)

I suspect the operation of the small battery through a station would be something like this.

  • As the train runs from the previous station, the power from the battery will be used by the train, to make sure that there is enough spare capacity in the battery to accommodate the predicted amount of energy generated by regenerative braking.
  • Under braking, the regenerative braking energy will be stored in the battery.
  • Not all of the kinetic energy of the train will be regenerated, as the process is typically around eighty percent efficient.
  • Whilst in the station, the train’s hotel services like air-conditioning, lights and doors, will be run by either the electrification if available or the battery.
  • When the train accelerates away, the train’s computer will use the optimal energy source.

The process will repeat, with the battery constantly being charged under braking and discharged under acceleration.

Lithium-ion batteries don’t like this cycling, so I wouldn’t be surprised to see dome other battery or even supercapacitors.

A Trip Between Liverpool and Wrexham Central in A Class 777 Train With A Battery

The train will arrive at Bidston station with 300 kWh in the battery, that has been charged on the loop line under the city.

I will assume that the train is cruising at 50 mph between the twelve stops along the twenty-seven and a half miles to Wrexham Central station.

At each of the twelve stops, the train will use regenerative braking, but it will lose perhaps twenty percent of the kinetic energy. This will be two kWh per stop or 24 kWh in total.

I usually assume that energy usage for hotel functions on the train are calculated using a figure of around three kWh per vehicle mile.

This gives an energy usage of 330 kWh.

But the Class 777 trains have been designed to be very electrically efficient and the train is equivalent in length to a three-car Class 507 train.

So perhaps a the calculation should assume three vehicles not four.

Various usage figures give.

  • 3 kWh per vehicle-mile – 247.5 kWh
  • 2.5 kWh per vehicle-mile – 206 kWh
  • 2 kWh per vehicle-mile – 165 kWh
  • 1.5 kWh per vehicle-mile – 123.8 kWh
  • 1 kWh per vehicle-mile – 82.5 kWh

Given that station losses between Bidston and Wrexham Central could be around 24 kWh, it looks like the following could be possible.

  1. With a consumption of 3 kWh per vehicle-mile, a Class 777 train could handle the route, but would need a charging station at Wrexham Central.
  2. If energy consumption on the train could be cut to 1.5 kWh per vehicle-mile, then a round trip would be possible.

It should also be noted that trains seem to do a very quick stop at Wrexham Central station of just a couple of minutes.

So if charging were to be introduced, there would need to be a longer stop of perhaps eight to ten minutes.

But the mathematics are telling me the following.

  • The Class 777 train has been designed to weigh the same empty as a current Class 507 train, despite carrying a five tonne battery.
  • If power consumption can be kept low, a Class 777 train with a battery can perform a round trip from Liverpool to Wrexham Central, without charging except on the electrified section of line between Liverpool and Bidston.
  • Extra stops would probably be possible, as each would consume about 2 kWh

I feel that these trains have been designed around Liverpool to Wrexham Central.

Conclusion

Wrexham Central here we come!

Other routes are possible.

  • Hunts Cross and Manchester Oxford Road – 27 miles
  • Ormskirk and Preston – 15 miles
  • Headbolt Lane and Skelmersdale – 6 miles
  • Ellesmere Port and Helsby – 5 miles
  • Kirkby and Wigan Wallgate – 12 miles

Chargers will not be needed at the far terminals.

Tyne And Wear Metro: Swiss Firm Stadler To Build New Fleet

The title of this post is the same as that of this article on the BBC.

This is the introductory paragraph.

Swiss firm Stadler has won a £362m contract to build a new fleet of trains for the Tyne and Wear Metro.

And this is one of Stadler’s visualisations of the trains for the Tyne and Wear Metro (T & W).

Compare this with a Stadler picture of a Class 777 train, that will soon be appearing on Merseyrail in Liverpool.

They would appear to be two very similar trains.

  • The same headlights and stylised M on the front.
  • One pair of double passenger doors in the first car.
  • Both new trains are articulated with four sections.
  • Train widths are Merseyrail Old – 2.82 metres, T & W Old – 2.65 metres and Merseyrail New – 2.82 metres.
  • The Merseyrail trains have a 75 mph operating speed and the T & W trains have one of only 50 mph.

The T & W trains have a pantograph and overhead electrification and the Merseyrail trains use third-rail electrification.

More Details On The Tyne And Wear Trains

This page on the NEXUS web site is entitled Nexus Unveils £362m New Tyne And Wear Metro Trains.

This is two paragraphs.

The new trains will cut Metro’s high voltage power consumption by 30% while providing 15 times better reliability than the current fleet. Metro’s 36 million passengers will benefit from modern features including wifi, charging points, air conditioning and a step-change in accessibility.

Among new features will be an automatic sliding step at every door of the new trains, making travel easier for Metro’s 50,000 wheelchair passengers as well as people with children’s buggies, luggage or bicycles.

The size of the energy saving, indicates that the trains will probably be using regenerative braking.

As it has been disclosed that the new Merseyrail trains will have a small battery for depot movements, will this also be used to handle the regenerative braking.

More details of the trains will be disclosed in the coming months.

Merseyrail And The Tyne And Wear Metro Are Similar

I have ridden Merseyrail many times and the Tyne and Wear Metro perhaps five times and it is surprising how similar the two systems are.

  • They are partly in tunnel.
  • There are a range of stations, including both ancient and modern, simple and complex.
  • Merseyrail is powered by 750 VDC third rail electrification and T & W by 1500 VDC overhead electrification. The power electronics on the two fleets, won’t be that different.
  • Both operators have ambitions to use 25 KVAC overhead electrification to extend services.
  • Both operators have ambitions to extend services on lines, that currently have no electrification. Merseyrail want to go to Preston, Skelmersdale, Warrington and Wrexham and T & W want to go to Blyth and Ashington.

It is no surprise to me, that Merseyrail and T & W have chosen to use two versions of the same Stadler train.

Expansion Of The Networks

Both networks are ambitious  and it appears to me, that they have ordered a train, that could be used to expand their networks.

Merseyrail

Merseyrail have proposed these expansions at various times.

  • Extension of the Northern Line from Ormskirk to Preston
  • Extension of the Northern Line from Hunts Cross to Warrington
  • Incorporation of the Borderlands Line from Bidston to Wrexham into the Wirral Line as a new branch.
  • A new branch of the Northern Line to Skelmersdale via the new station at Headbolt Lane.
  • Passenger services on the Canada Dock Branch.

Merseyrail now have the trains to handle this expansion.

  • They may need to purchase a few extra trains.
  • Some charging points or electrification may be needed.

Note that Bidston and Wrexham is less than thirty miles of unelectrified line, so I suspect that the new trains can handle this range.

Other places within a similar range include.

  • Preston from Ormskirk
  • Wigan Wallgate from Kirkby
  • Manchester Oxford Road from Hunts Cross, via Warrington Central.
  • Chester from Liverpool Lime Street via Runcorn, Frodsham and Helsby.

The four terminal stations all have existing bay platforms.

Tyne And Wear Metro

The Tyne And Wear Metro have proposed these expansions at various times.

  • Sunderland city centre to Doxford Park
  • South Shields to Sunderland
  • Washington, either via the disused Leamside line or a new route

But as the Government is funding a study into linking Blyth and Ashington to Newcastle, which I wrote about in £500m Fund To Restore Beeching Rail Cuts Goes Ahead Amid Criticism, I wouldn’t be surprised that this route is developed.

A lot of my comments about expanding the Merseyrail network, can be applied to the T & W.

  • They may need to purchase a few extra trains.
  • Some charging points or electrification may be needed.

None of the proposed extensions seem particularly long and places like Blyth, Ashington and Washington should be able to be reached on battery power.

Tram-Train Operation

The Wikipedia entry for Merseyrail has a section called tram-trains.

Two possible routes are indicated.

  • Liverpool Lime Street to John Lennon Airport, using street-running from Liverpool South Parkway.
  • Kings Dock to Edge Hill

I have heard others mentioned.

The Wikipedia entry for the Tyne and Wear Metro also mentions street-running.

Stadler have extensive experience of trams and tram-trains and built the Class 399 tram-trains for the Sheffield Supertram.

Stadler also provided the trains for the unique tram-train system in the German town of Zwickau, where diesel multiples units share the tram tracks to access the town centre.

The picture shows the train at its stop in the centre.

I’m sure Stadler know how to enable street-running with the UK’s smaller trains.

Stadler’s trains, trams and tram trains also seem to have a high degree of articulation and seem to be able to take tight corners with ease.

The picture was taken inside a Class 399 tram-train, as it traversed the tight curve under the M1 motorway, where the tram and the train sections of the route to Rotherham join.

Looking at the pictures of the Class 777 trains, I feel they could be able to take tighter curves than most trains.

The Dead Elephant In The Room

Several local services on Merseyside and in the North East are run by Northern, which is now being taken over the Government.

The Department for Transport, hasn’t disclosed any plans yet, but it is likely that some routes could be handed to Merseyrail and the T & W.

There is a loose precedent for this happening. In North-East London the poorly performing Lea Valley Lines from Liverpool Street to Chingford, Cheshunt and Enfield Town were moved from Greater Anglia to London Overground in 2015. No-one feels they should be returned and there are rumours that more services in the area will move to the London Overground.

So what services could be moved?

Merseyrail

These diesel services could surely be moved to Merseyrail.

  • Omrskirk and Preston – 16 miles
  • Liverpool Lime Street and Manchester Oxford Road via Warrington Central – 27 miles

The distances are the length of track without electrification.

It could also be argued that Greater Manchester would get its share of the Northern routes, but I can envisage Class 777 trains or similar running the following routes.

  • Southport and Manchester Victoria – 27 miles
  • Kirkby and Manchester Victoria – 28 miles

As before, the distances are the length of track without electrification, but these could be reduced considerably with electrification from Salford Crescent to Wigan Wallgate.

It should be noted that Greater Manchester has ambitions to run tram-trains to Wigan Wallgate via various routes.

The demise of Northern probably allows these routes to be taken over by Greater Manchester.

  • Manchester Piccadilly and Buxton – 16 miles
  • Manchester Piccadilly and Hadfield/Glossop – Electrified
  • Manchester Victoria and Blackburn – 14 miles
  • Manchester Victoria and Clitheroe – 24 miles
  • Manchester Victoria and Rochdale – 11 miles
  • Manchester Victoria and Stalybridge – 8 miles
  • Manchester Victoria and Wigan Wallgate – 10 miles

Again, the distances are the length of track without electrification.

Buxton and Clitheroe could be difficult because of the gradients involved, but as in South Wales, bi-modes might be the solution if the routes were run back-to-back.

This simple analysis shows how Northern’s demise will ask questions all over the North.

Tyne And Wear Metro

These diesel services could surely be moved to the T & W.

  • Newcastle and Morpeth – Electrified
  • Newcastle and Chathill- Electrified

I also think, that these services could be restructured, if the Blyth and Ashington routes are developed for the T & W.

The trains could also reach to Hexham, which is just 22 miles from electrification.

Middlesbrough is probably too far, as the station is thirty five miles from the electrification at Sunderland.

But electrification of the Durham Coast Line would allow the T & W Metro to serve the new station at Howden and reach Middlesbrough and possibly Nunthorpe.

Conclusion

I can see both Merseyrail and the Tyne and Wear Metro significantly extending their networks in the next few years.

The new trains, with their batteries and dual-voltage capability are built for expansion.

Tram-train or street running will help.

Several important new areas are within battery range.

I can also see other cities using similar Stadler technology to create local Metros.

Manchester, Middlesbrough, Preston and Sheffield come to mind.

Using similar technology would surely allow joint services and sharing of knowledge and designs to enable cost savings.

Mule Trains Between Liverpool And Norwich

I have done two trips to Liverpool in the last week.

On Saturday, I saw this collection of one-car Class 153 trains with a two-car Class 156 train thrown in.

They were forming one of East Midlands Railway‘s Liverpool and Norwich services.

And then yesterday, I had to travel between Liverpool and Sheffield and this was the collection of trains that took me.

So what was it like?

It started badly, with the driver announcing that because of the late arrival due to an undisclosed problem with the incoming train, that we would be leaving ten minutes after the planned departure time of 1551. He also indicated that our late departure meant that we would be stuck behind one of Northern’s services.

In the end, despite the gloomy faces of passengers we left twelve minutes late at 1603.

It was a bit like one of those classic films, where an ancient train escapes in the nick of time, with a lot of important and assorted passengers.

The asthmatic Cummins diesels under the train could be heard straining.

  • But the driver was at the top of his game and the train was running smoothly towards Manchester at close to 75 mph, which is the maximum speed of a Class 153 train.
  • At Manchester Piccadilly, the driver had pulled back two minutes.
  • There were obviously, no problems on the Dove Valley Line and the driver pulled back another minute before Sheffield, to arrive nine minutes late.

Looking at Real Time Trains, the train ran well until March (The place, not the month!), but there was some form of delay there and sadly it was thirty-four minutes late into Norwich.

The Train Was Clean

I should say there was nothing wrong with the train except for its design and age. It was also as clean as you can get one of these trains. The toilet, that I used was better than many I’ve used on trains and worked as it should.

Customer Service

East Midlands Railway had loaded a trolley and a steward and in the two hours I was on the train, he came through twice. The only problem for me, that he had no card machine, but I did find a fiver in my briefcase.

At least it was very drinkable. Even, if I hate those plastic tubs of milk, as they are difficult to open with one good hand.

Where Did Two Cars Go?

I had been fairly certain, that we had started with six cars, but we only arrived in Sheffield with four Class 153 trains.

I suspect that the trouble that delayed the train, concerned two cars and these were left on the naughty step or the end of Platform 6 in Liverpool Lime Street station.

Being Fair To East Midlands Railway

This service used to be run by a four-car formation of two-car Class 158 trains, but these have been causing trouble lately and they will be replaced by Class 170 trains cascaded from other operators.

But because of late arrivals of new trains the much better Class 170 trains haven’t arrived yet.

The driver, steward and other staff did a good job and I feel that the steward enjoyed it. No-one was abusive and stories were just exchanged, as we climbed across the Pennines in what by Sheffield was a very crowded train.

Class 153 trains may have been built as a stop-gap for short branch lines, but you couldn’t fault their performance.

Unless of course, one caused the delay at March, by expiring in a cloud of blue smoke.

Other Observations

These are other observations.

Scheduled Journey Times

On my journey the scheduled times were

  • Liverpool and Manchester Oxford Road – forty-seven minutes.
  • Liverpool and Sheffield – one hour and forty-eight minutes.
  • Liverpool and Nottingham – two hour and forty minutes.
  • Liverpool and Norwich – Five hours and twenty-seven minutes

The train considering the configuration, nearly achieved them.

It’s probably the motoring equivalent of doing the journey in a Morris Minor!

The Nine Stops Were Executed Perfectly

There were nine stops on my journey and eight took less than a minute, with Sheffield taking four, as the driver and crew changed.

A modern train like a Class 755 train, with fast acceleration and level boarding could probably save up to three minutes a time on each stop.

The Route Is A Genuine 75 mph Railway In Good Condition

I was checking the speed of the train on parts of the route and the driver had his motley crew at a steady 75 mph for long periods.

  • The train was riding well, indicating to me, that both trains and track were in reasonably good condition.
  • Note that 75 mph is the maximum speed of a Class 153 train.
  • The train recovered three minutes on the late departure from Liverpool.

I can see a faster train and improvements to the route, some of which are underway, could reduce the journey time by a few minutes.

Could Merseyrail’s New Class 777 Trains Work To The Bay Platform At Oxford Road?

Merseyrail’s new Class 777 trains will have the following performance.

  • A possible range of perhaps 40-50 miles on battery power.
  • An operating speed of 75 mph.
  • An acceleration rate of 1.1 m/sec², which is faster than a Class 153 or Class 170 train.
  • Fast stops due to regenerative braking, fast acceleration and level boarding.

As Liverpool Lime Street to Oxford Road is thirty four miles of which nine is electrified, I suspect that these new trains could extend Merseyrail’s Northern Line service from Hunts Cross to Manchester Oxford Road.

  • Two trains per hour (tph), but I’m sure four tph would transform the area.
  • I doubt any track modifications would be needed.

But would Liverpool and Manchester be able to sort out the local politics?

The Future Of The Liverpool And Norwich Service

This service will probably be spilt into two services.

  • Liverpool Lime Street and Derby, which could be run by TransPennine Express or Northern Trains.
  • Derby and Norwich, which would be run by East Midlands Railway.

As to the trains to be used, consider the following.

The Liverpool and Derby leg would probably need six trains, with the same number needed for Derby and Norwich, or twelve in total.

Currently, eleven or twelve is needed for the longer service.

Sections of the route like through Manchester and between Grantham and Peterborough are electrified.

There are even sections of route, where 125 mph running is possible.

Run reliably to an hourly frequency, I think that this service could attract passengers, especially, as it would serve Derby and extra stops like Ilkeston and Warrington West could be added.

This leads to the following trains being possibilities.

Class 802 trains – 125 mph bi-mode train of which TransPennine Express have 19 trains.

Class 185 trains – 100 mph diesel train of which TransPennine Express have 51 trains.

Class 804 trains – 125 mph bi-mode train of which East Midlands Railway have ordered 33 trains.

Class 755 trains – 100 mph diesel train of which Greater Anglia have 38 trains, which are based at Norwich.

Alstom Breeze hydrogen trains could be ideal for Liverpool and Derby.

Note.

  1. Greater Anglia and East Midlands Railway are both subsidiaries of Abellio.
  2. Developments of Class 755 trains could include battery and hydrogen versions.
  3. I suspect that 125 mph trains may be required for both legs, to maximise capacity on the East Coast Main Line and Midland Main Line.

Could High Speed Two Trains Serve Chester?

This may seem a slightly outrageous proposal to run High Speed Two trains to Chester.

  • The city is a major tourist destination.
  • Despite its closeness to Crewe it is a major rail hub, with services across Wales to Cardiff, Holyhead and Llandudno and along the border between England and Wales to Shrewsbury and Newport.
  • Merseyrail serves the city and the station can be considered to be part of Liverpool’s extensive commuting area. This service is likely to be more reliable and faster with the delivery of new Class 777 trains.
  • For parts of Merseyside, travelling to London or Manchester Airport, is easier via Chester than Liverpool Lime Street or Liverpool South Parkway.

If the promoters of High Speed Two are serious about creating a railway for the whole country, then I feel that running trains direct to and from Chester could be very beneficial for the towns and cities, that can be served by the current network at Chester.

Current And Possible Timings

Currently, trains take two minutes over two hours between Euston and Chester.

When Avanti West Coast introduces the new Hitachi AT-300 trains on the route, the following times will be possible.

  • Euston to Crewe via West Coast Main Line – 90 minutes – Fastest Pendelino
  • Crewe and Chester – 24 minutes – Current timing

This would give a time of one hour and 54 minutes, which is a saving of 8 minutes. But a lot of carbon would not be emitted.

I estimate, that with High Speed Two Phase 2a completed, the following timings will be possible.

  • Euston to Crewe via HS2 – 55 minutes – HS2 website
  • Crewe and Chester – 24 minutes – Current timing

This would give a time of one hour and 19 minutes, which is a saving of 43 minutes.

Infrastructure Needed

There will need to be some infrastructure changes.

Platform Lengthening At Chester Station

The station would probably be served by two-hundred metre long classic-compatible, which might need some platform lengthening.

This Google Map shows the station.

It looks to me, that there is plenty of space.

Will Chester And Crewe Be Electrified?

We know little about the capabilities of the trains proposed by the various manufacturers.

But, I wouldn’t be surprised that one or more of the proposals use batteries for one of the following purposes.

  • Regenerate braking.
  • Emergency power.
  • Range extension for up to perhaps sixty miles.

As Chester and Crewe stations are only twenty-one miles apart with no intermediate stations, which will be run at an average speed of only 52 mph I don’t think it will be impossible to extend the service to Chester on battery power.

If electrification is required I wrote about it in Hitachi Trains For Avanti.

As it is only just over twenty miles, I don’t think it will be the most challenging of projects, although there does seem to be a lot of bridges.

Electrification would also allow Avanti West Coast’s Hitachi trains to run on electricity to Chester.

What About Holyhead?

Holyhead could become a more important destination in the next few years.

It is probably the best alternative to avoid flying and driving between Great Britain and the Island of Ireland.

And who can accurately predict, what effect Brexit and thinking about global warming will have?

I have a feeling that after electrification to Chester, using on-board energy storage could be used West of Chester.

It is very difficult to predict battery ranges in the future, but I can see a two hundred metre long classic-compatible train on High Speed Two being able to reach Holyhead on battery power, with or without some limited extra electrification.

I estimate that with some track improvements, that it will be possible to travel between Euston and Holyhead in around three hours.

Conclusion

It looks to me, that when High Speed Two, think about adding extra destinations, Chester could be on the list.

I also suspect that if it can be run without full electrification, Euston and Holyhead could be a valuable route for Avanti West Coast.

The New Warrington West Station

These pictures show the new Warrington West station.

The station looks to have a similar layout to Maghull North station, which I described in Maghull North Station – 29th June 2018.

The two stations have a lot in common.

  • The cutting and the contours of the land are used to create a simpler station.
  • Provision for car-parking.
  • Links to the bus network.
  • Enough car-parking. Warrington West has 387 spaces, with 156 spaces at Maghull North.
  • Fully step-free.
  • A separate amenity building, with a booking office, waiting area and toilets.

Surprisingly, the two stations were designed by different architectural practices.

The Major Problem

The major problem is that Warrington West station only has two trains per hour (tph), in the Off Peak.

  • The route connects Liverpool Lime Street to Manchester Airport and Manchester Oxford Road stations alternately.
  • Manchester Airport services also call at Manchester Piccadilly station.
  • All services call at Deansgate station for the Manchester Metrolink.
  • There are links to Merseyrail’s Wirral Line at Liverpool Lime Street.
  • There are links to Merseyrail’s Northern Line at Liverpool South Parkway and Hunts Cross.
  • Liverpool South Parkway, Warrington West and Birchwood stations are already step-free.
  • Hunts Cross, Irlam, and Manchester Oxford Road stations are in the queue for step-free access.
  • Most of the services on Liverpool’s Merseyrail network have four tph.
  • There is a lot of housing and other development on this route,

I’m sure that four tph and full step-free access will be needed on this route before too long.

Possible Electrification

It could be argued that this route between Liverpool Lime Street and Manchester Oxford Road stations, should be fully-electrified.

Currently, just over twenty-eight miles of the route between Manchester Oxford Road and Liverpool South Parkway stations is not electrified.

  • Between Liverpool South Parkway and Liverpool Lime Street stations has 25 KVAC overhead electrification.
  • Between Hunt’s Cross and Liverpool Central station is part of Merseyrail’s Northern Line and has 750 VDC third-rail electrification.
  • Manchester Oxford Road station has 25 KVAC overhead electrification.
  • The bay platform at Manchester Oxford Road station could be electrified or fitted with a fast charging station for battery trains.
  • Battery trains can easily do forty miles after a charge of perhaps ten minutes, as I wrote in Retired London Underground Train Travels Forty Miles Solely On Battery Power.

I think, that the route between Manchester and Liverpool via Warrington is a very suitable route for running using battery-electric trains.

  • It is electrified at both ends.
  • The section without electrification is less than thirty miles.
  • Charging can be performed using the existing electrification or with a charging station at Manchester Oxford Road station.
  • Northern’s Class 331 trains, which are being built by CAF. I suspect that battery-electric versions are possible as CAF have successfully built battery-electric Urbos trams for Luxembourg, Seville and the West Midlands.
  • Merseyrail’s new Class 777 trains, can be converted to battery-electric operation.
  • The route is not busy.
  • There aren’t many freight trains on the route.

Using battery-electric trains would probably cause a lot less disruption, than full electrification of the route.

Possible ways to increase trains on the route include.

  • Merseyrail could extend Northern Line trains from Hunt’s Cross to Manchester Oxford Road.
  • The Manchester Metrolink could even be connected to the route at somewhere near Pomona and run tram-trains to Liverpool.
  • Northern could run battery-electric trains on the route.

There must also be the possibility of running hydrogen-powered trains on the route.

Negotiations between Liverpool and Manchester over who provides the extra services will be tough.

Conclusion

It is a neat new station, that will attract passengers.

The station could be an important link in improved rail services between Liverpool and Manchester via Warrington.

  • This route could probably handle at least six tph in both directions.
  • Would turning back four tph in the bay platform at Manchester Oxford Road station, ease the pressure on the Castlefield corridor.
  • It serves the important stations of Liverpool Lime Street, Liverpool South Parkway, Manchester Oxford Road, Manchester Piccadilly and Manchester Airport.
  • It connects Merseyrail’s to Northern and Wirral Lines and the Manchester Metrolink.
  • An increasing number of stations on the route are step-free.

I suspect too, that it could be an important feeder line for High Speed Two.

Protests After Claim That Hitachi Has Lost T&W Contract

The title of this post is the same as that of this article on Railnews.

This is the introductory paragraphs.

There have been protests in north east England after a report claimed that Hitachi has been ruled out of the three-way contest to build a £500 million fleet for Tyne & Wear Metro.

The other contenders are CAF and Stadler, and the source of the claims says ‘insiders’ at Nexus have been told that Hitachi will be ‘overlooked’.

It should be noted that the two other bidders have orders for similar trains in the pipeline.

CAF

In TfL Awards Contract For New DLR Fleet To Replace 30-year-old Trains , I wrote about how CAF had been awarded the contract for new trains for the Docklands Light Railway.

I also said this about the possibility of CAF being awarded the contract for the new trains for the Tyne and Wear Metro.

In Bombardier Transportation Consortium Preferred Bidder In $4.5B Cairo Monorail, I indicated that as the trains on the Tyne and Wear Metro and the trains on the Docklands Light Railway, are of a similar height and width, it might be possible to use the same same car bodies on both trains.

So now that CAF have got the first order for the Docklands Light Railway, they must be in prime position to obtain the Tyne and Wear Metro order!

A second order would fit well with the first and could probably be built substantially in their South Wales factory.

Stadler

Stadler seem to be targeting the North, with new Class 777 trains for Merseyrail and Class 399 tram-trains for Sheffield and bids in for tram-trains and and new trains for the Tyne and Wear Metro.

Their trains are both quirky, accessible and quality and built to fit niche markets like a glove.

Only Stadler would produce a replacement for a diesel multiple unit fleet with a bi-mode Class 755 train, with the engine in the middle, that is rumoured to be capable of running at 125 mph.

Note the full step-free access between train and platform, which is also a feature of the Merseyrail trains.

Does the Tyre and Wear Metro want to have access like this? It’s already got it with the existing trains, as this picture at South Shields station shows.

Stadler’s engineering in this area, would fit their philosophy

I first thought that Stadler would propose a version of their Class 399 tram-trains. for the Tyne and Wear Metro and wrote Comparing Stadler Citylink Metro Vehicles With Tyne And Wear Metro’s Class 994 Trains.

This was my conclusion.

I am led to the conclusion, that a version of the Stadler Citylink Metro Vehicle similar to those of the South Waes Metro, could be developed for the Tyne and Wear Metro.

My specification would include.

  • Length of two current Class 994 trains, which would be around 111 metres.
  • Walk through design with longitudinal seating.
  • Level access between platform and train at all stations.
  • A well-designed cab with large windows at each end.
  • Ability to use overhead electrification at any voltage between 750 and 1500 VDC.
  • Ability to use overhead electrification at 25 KVAC.
  • Pantographs would handle all voltages.
  • A second pantograph might be provided for reasons of reliable operation.
  • Ability to use onboard battery power.
  • Regenerative braking would use the batteries on the vehicle.

Note.

  1. Many of these features are already in service in Germany, Spain or Sheffield.
  2. The train would be designed, so that no unnecessary platform lengthening is required.
  3. As in Cardiff, the specification would allow street-running in the future.
  4. Could battery range be sufficient to allow new routes to be developed without electrification?

I also feel that the specification should allow the new trains to work on the current network, whilst the current trains are still running.

But since I wrote that comparison in June 2018, Merseyrail’s new trains have started to be delivered and Liverpudlians have started to do what they do best; imagine!

The Tyne and Wear Metro has similar ambitions to expand the network and would a version of the Class 777 train fit those ambitions better?

Conclusion

I wouldn’t be surprised if Hitachi misses out, as the experience of the Docklands Light Railway or Merseyrail fed into the expansion of the Tyne and Wear Metro could be the clincher of the deal.

They would also be the first UK customer for the Hitachi trains.
