Third Rail Or Batteries Could Replace Southern Diesel Trains
The title of this post, is the same as that of this article on Railway Gazette International.
I first wrote about the Uckfield Branch eight years ago, in Future-Proofing The Uckfield Branch.
Since then I have written about this branch several times and I have also read several articles in the railway press.
These are some of my posts.
- Discontinuous Electrification Using IPEMUs – April 30th, 2016
- Will Innovative Electrification Be Used On The Uckfield Line? – August 24th, 1917
- Battery Trains On The Uckfield Branch – August 26th, 2018
- Battery Electrostars And The Uckfield Branch – September 30th, 2019
- Alstom Hydrogen Aventras And The Uckfield Branch – November 12th, 2021

It is an utter disgrace that no decision has been made in eight years about how to decarbonise to Uckfield.
The Railway Gazette article says this about third-rail electrification.
GTR is one of two operators participating in a Rail Safety & Standards Board project reviewing the safety, legal and regulatory issues around third rail electrification infill projects. This is looking at whole transport system safety, project and economic risks.
Bi-monthly South of England Diesel Replacement Programme meetings are held by DfT, Network Rail and GTR to review progress and options for third rail electrification of the Uckfield line or battery train trials. This includes reviewing the lessons learned from the use of bi-mode trains by GWR and LNER, and the failed attempt to deploy tri-mode Class 769 units on GWR’s North Downs services.
Could it just be that there is such fear that there will be a major incident, where several people are killed, that third-rail electrification is always turned down, by the Office of Road and Rail?
The Railway Gazette article also says this about battery trains, under a heading of Batteries Viable.
In the absence of electrification, GTR says battery powered trains are also a viable option for its diesel routes. Batteries can be charged while trains are running on electrified lines or through a rapid recharging facility at a terminus, although additional infrastructure and electrical upgrades may be needed.
I suspect that after a few teething troubles, Merseyrail would agree.
Hydrogen is also dismissed with this paragraph.
GTR has considered hydrogen but says it can only be considered a net zero-compliant fuel if it is produced from low or zero-carbon energy sources. It is also relatively inefficient with studies indicating an efficiency rate of around 35% to 40%.
It looks to me, that battery-electric trains are a viable solution.
So would it not be a good idea to take the decision to create a battery-electric prototype from a four-car Electrostar or a Class 350 train, so that the final decision can be taken after everybody on the committee has have a ride first?
Better still, why not stage a competition, where manufacturers, leasing companies or remanufacturers can build a four-car train and enter.
Allow the public to ride in them and then see what is best against a range of criteria.
The King could even get involved, as he’s probably one of the few people left, who rode the original British Rail BEMU between Aberdeen and Ballater, to get to Balmoral.

I’d have thought that there are enough Class 379s off lease to make them a candidate for conversion to battery/3rd rail operation. So far as enhanced safety of 3rd rail goes, reading the RSSB Report T1214 on 21st Century DC Electrification Infill they spend a good deal of time considering Alstom’s Allimentation Par Sol (APS). Seems to me it’s OK for a tramway but I’m not convinced that it works for heavy rail.

I do wonder that there’s a cunning plan being developed,
There are these trains coming to the end of their working life or becoming surplus to requirements.
30 x Class 379
Perhaps 50 x Class 387
Perhaps 30 x Class 377
30 x Class 321 Renatus
87 x Class 350
That is 227 four-car 100 mph or 110 mph trains.
Porterbrook, Angel Trains and Eversholt have wasting assets.
I believe that a battrification of these trains, all of which are almost in as new condition, would be almost enough to decarbonise most of the UK network, with the addition of a few CAF and Hitachi new battery electric trains.
Modification of the Class 350s would fit well with SWR’s other Desiros.
