The Next Generation: LNER Reveals Exciting New Details Of Upcoming East Coast Main Line Trains

The title of this post, is the same as that of this press release from LNER.

This is the sub-heading.

A new generation of comfort and speed is coming for LNER customers on the East Coast Main Line with the introduction of 10 state-of-the-art intercity trains, delivering improved journey experiences.

These two paragraphs introduce the trains.

LNER has released a fleet name and the latest interior images of the trains, built by manufacturer CAF and financed by Porterbrook, to show customers what they can expect following their introduction to the UK rail network in the coming years.

The new fleet will help support and accommodate strong demand for rail travel on the East Coast Main Line. Since Covid, LNER has seen a year-on-year increase in customers, with more than 24 million customers in 2024-25. The introduction, in December 2025, of a new, transformative timetable has brought an extra 60,000 seats per week across the route, and new CAF-built trains will further grow capacity and reliability.

Note.

  1. The trains will be ten cars long.
  2. The trains will be tri-mode trains, which will be able to use 25 KVAC Overhead electricity, diesel and battery power.
  3. The trains will have a top speed of 125 mph.
  4. The trains will be named Serenza.

The trains will be numbered as Class 897 trains.

I have some further thoughts.

What Diesel Engines Will Be Used?

I asked Google AI this question and received this answer.

The British Rail Class 897 Civity, designed by CAF for London North Eastern Railway, are tri-mode electro-diesel multiple units. While they are built for electric, battery, and diesel operation, specific details regarding the engine manufacturer for the Class 897’s diesel power units have not been officially announced or detailed in public documentation.

Information on the specific model of the diesel engines (e.g., Cummins, MAN) is not available in the provided search results.

CAF’s other diesel-multiple units built in the UK,  as eight of these Class 897 trains will be, have German-made Rolls-Royce mtu diesel engines.

Consider.

  • American diesel-engine manufacturer; Cummins is specifically-mentioned by Google AI.
  • Cummins have a large diesel engine factory in Darlington, just round the corner from Darlington station.
  • Cummins are known to be decarbonising the company and are producing a range of diesel-engines, that can be converted to run in a carbon-zero mode on hydrogen.
  • Wrightbus now produce the Streetdeck Ultroliner EU6 with a Cummins engine. They also say on their web site, that the bus can be decarbonised, by converting to electric power.
  • Stadler produce the Class 99 locomotive with a Cummins engine.

An alternative and possibly simpler way to decarbonise the Streetdeck Ultroliner EU6s, the Class 99 locomotives and the Class 897 trains might be to convert the diesel engines to zero-carbon hydrogen?

I asked Google AI how many railway locomotives use Cummins diesel engines and received this reply.

More than 13,000 Cummins rail engines are in operation globally, powering various locomotives and railcars. They are heavily utilized in both passenger and freight applications, with over 10,000 underfloor engines in service for diesel railcars. They are commonly found in locomotives built by companies like Siemens and Stadler.

Replacing that number of diesel engines will be a large amount of work. And what better place to base the European side of that business, than in the historic railway town of Darlington?

Will The Class 897 Trains Be Able To Take The Great Northern and Great Eastern Joint Line?

As I write this post,  some trains will be replaced by coaches at the weekend, so there is not much point in my mind for tri-mode trains not to be able to take the Diversion using the onboard diesel and battery power.

Google AI gave this answer.

Yes, the Class 897 “Serenza” trains, designed for LNER, are expected to be capable of using the Great Northern and Great Eastern Joint Line (GNGE). As tri-mode electro-diesel multiple units, they are designed for flexibility and can utilize battery power to navigate routes like the GNGE through Lincoln during engineering works or overhead wire issues.

I suspect it could also allow combining services like Lincoln and Middlesbrough if required.

Will The Class 897 Trains Be Able To Take Services To The North Of Scotland?

Google AI gave this answer.

Yes, LNER’s new Class 897 tri-mode trains are designed to operate across their entire network, including routes to Scotland, utilizing electric, diesel, or battery power. These 10-car units will replace older fleets, supporting, as noted by The Anonymous Widower, services from London to the North of England and Scotland, with deployment scheduled to begin from 2027.

Thanks, for the link, Google!

Will LNER Take On The Airlines To Scotland?

Consider.

  • The Class 897 trains running as diesel tri-modes will probably emit less carbon dioxide, than the current Class 800/802 diesel bi-modes.
  • If the Class 897 trains could run as hydrogen tri-modes, they could probably be zero-carbon trains.
  • Hydrogen would not be needed South of Stirling or Edinburgh.

Think of the advertising possibilities to change travellers from the airlines to the trains.

Hydrogen-tri-mode trains make sense

Will The Class 897 Trains Be Able To Take Services To The New Destinations In South Yorkshire?

By reading a map, I feel that this route will be possible.

  1. Retford, where the train would leave the East Coast Main Line
  2. Worksop, where there is a good cafe with excellent cakes.
  3. Woodhouse for Advanced Manufacturing Research Centre.
  4. Sheffield with a reverse.
  5. Meadowhall for the shopping.
  6. Barnsley Interchange
  7. Wakefield Kirkdale.
  8. Leeds

Note.

The route I mapped out is not much different to Hull Trains’s route to Sheffield, that I wrote about in FirstGroup Applies To Run New London To Sheffield Rail Service.

  1. Trains could go on from Leeds to York, Darlington, Newcastle and Edinburgh on the East Coast Main Line.
  2. Trains could go on from Leeds to Settle, Carlisle, Lockerby, Motherwell and Glasgow Central on the Settle and Carlisle Line and the West Coast Main Line.
  3. I do like the idea of a King’s Cross and Glasgow service on the Settle and Carlisle.

There are certainly interesting possibilities for trains to take a number of routes through South Yorkshire.
