Battery And Hydrogen Trains For ScotRail ‘Could Make Scotland A Global Leader’ In Zero-Emission Transport
The title of this post is the same as that of this article in the Scotsman.
This is the first paragraph.
New fleets of cutting-edge trains expected to include battery and hydrogen power are to be ordered for ScotRail which the rail industry believes will put Scotland at the forefront of zero-emission transport.
Other points from the article.
- Talgo appear to have passed the story to Scotland on Sunday.
- Three routes are mentioned; Borders Railway, Fife Circle and Glasgow-East Kilbride.
- The new trains could help phase out diesel trains by 2035, which is Scottish Government policy.
- The Inter7City trains might be replaced by 2030.
- Talgo hopes to win an order for its factory in Fife.
Talgo’s Managing Director is quoted as saying, they are starting testing of a hydrogen and electric train with a range of 311 miles.
Consider.
- I wrote about this train in Talgo To Begin Fuel Cell Loco Trials.
- Talgo’s hydrogen and electric train would be ideal for Scotland’s railways of which only forty percent are electrified.
- A four or five-car high specification hydrogen and electric train would be ideal for the Inter7City routes, if it were built specifically for the routes.
- The range would cover all of Scotland.
- Hydrogen hubs are being planned all over Scotland.
- Scotland have 26 Inter7City trainsets.
This could be a rather nice order to fund the factory and test all the trains close to the factory.
Is there a better place to show off your new train to a prospective buyer than the Highlands of Scotland?
In A Class 319 Train, But Not As We Know It!, I told this tale.
I am reminded of a tale, that I heard from a former GEC manager.
He was involved in selling one of GEC’s Air Traffic Control radars to a Middle Eastern country.
The only working installation of the radar was at Prestwick in Scotland, so he arranged that the dignitaries and the sales team would be flown to Prestwick in GEC’s HS 125 business jet.
As they disembarked at Prestwick and walked to the terminal, the pilot called the GEC Manager over.
The pilot told him “The Scottish Highlands at this time of the year, are one of the most beautiful places in the world! Would you and your guests like a low-level tour on the way back? I can arrange it, if you say so!”
Despite knowing GEC’s draconian attitude to cost control he said yes.
The sale was clinched!
I’m sure that Talgo will exploit the scenery and the local produce.
Talgo’s Hydrogen Trains
This page on the Talgo web site, is entitled Talgo’s Hydrogen Train Will Be Ready In 2023.
This paragraph gives an overview of Talgo’s hydrogen power system.
This system is configured as a modular solution that can be installed on all types of trains, as well as in upgrades from diesel to hydrogen. However, it has been specifically designed for the Vittal platform for Commuter and Regional trains, which Talgo has presented in the bidding process for various tenders in Spain and other countries.
And these two paragraphs describe Talgo’s hydrogen trains in more detail.
This innovative system uses hydrogen batteries that provide the energy for the train’s electric motors. It is powered by renewable energy sources, such as solar photovoltaic or wind, which produce hydrogen that is stored and then used to power fuel cell-based propulsion systems, such as the one designed by Talgo. The system is complemented by batteries that increase the speed of the train when it starts, taking advantage of the braking system to recharge it.
Unlike the extended battery systems in the automotive industry, hydrogen (H2) technology is the logical answer to the needs of heavy transport and, in particular, of those railway lines that do not have catenary electrification systems, and which today depend on trains powered by diesel engines. The hydrogen system designed by Talgo enables conventional network lines to be “electrified” without the need for costly and lengthy adaptation operations, and without the use of fossil fuels.
What do they mean by hydrogen batteries? Looking at the German and the Spanish on the page, I think Talgo means hydrogen fuel cells.
The Rebuilding Of Ukraine
It should be noted that Talgo have sold trains in the past to Russia, which has a gauge of 1.520 metres, which lies between Iberian gauge of 1.668 metres and our standard gauge of 1.435 metres.
- Talgo have also sold trains to Germany, who use standard gauge.
- Talgo have built Strizh trains for Russia, that are both standard gauge and Russian gauge for running between Berlin and Moscow.
- According to the BBC and The Times, Ukraine’s railways have been an important lifeline during the Russian invasion, but pictures show they are in need of modernisation and more electrification.
- The Strizh trains or a development would surely be ideal for running between Kviv and Berlin, Budapest, Prague and Warsaw.
- There would also appear to be a need for a hydrogen and electric regional train to reconnect the country back together.
- Other countries using Russian gauge include Mongolia, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan, Armenia, Azerbaijan, Georgia, Belarus, Moldova, Estonia, Latvia, Lithuania, and Finland.
So are Talgo positioning themselves to take part in the modernisation of Ukraine’s railways, once the war is over?
- Development and testing is done in Spain and Scotland.
- Manufacturing could be done in Spain and Scotland.
- Delivery from Scotland could either be by ship or if they were dual-gauge trains, they could be hauled through the Channel Tunnel and then through Germany and Poland.
As Talgo has the technology, I can certainly see them exploiting the Russian gauge market once Vlad the Mad has gone.
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.
- All power changeovers could be arranged to take place in stations.
- Gravity can be used to assist trains from East Kilbride to Glasgow Central.
- Glasgow Central and Barrhead services don’t need trains with batteries.
- 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.
- 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.
- Late delivery of the battery-electric trains will not delay the overall project, if there are enough diesel multiple units to fill in.
- 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.
Plans To Introduce Battery Powered Trains In Scotland
The title of this post, is the same as that of this article in the Scotsman.
This is said about the routes.
Hitachi said the trains could run up to 60 miles on batteries.
It said recharging would take ten to 15 minutes.
That would mean the trains could run beyond Dunblane – the northern extent of ScotRail’s electrified network – as far as Perth and Dundee.
Hitachi has suggested other routes they could be used on including from Glasgow to East Kilbride and Kilmarnock, and on a Glasgow northern suburban line to Anniesland via Maryhill.
The train described in the article sounds very much like the Hitachi Regional Battery Train, which is described in this Hitachi infographic.
My only reservation is that the article is from 2019.
Since then, Scotland has decided to run battery-electric trains to Leven, as I wrote about in Trains On The Levenmouth Rail Link.
