The chap in that clip said 'Hitachi - Alstom' in a joint venture. See https://www.alstom.com/press-releases-news/2019/6/alstom-unveils-proposed-hs2-train-designPedro, who is providing the engines for the trains?
Thanks
Strictly speaking there will be no engines, the trains will be multiple units with powered axles throughout the train.The chap in that clip said 'Hitachi - Alstom' in a joint venture. See https://www.alstom.com/press-releases-news/2019/6/alstom-unveils-proposed-hs2-train-design
How is the power generated, electric, diesel, hydrogen?Strictly speaking there will be no engines, the trains will be multiple units with powered axles throughout the train.
A steel wheel on a steel rail can only produce a force at the rail head equivalent of a fifth of the wheel loading which severely limits acceleration and braking performance if the locomotive has to do all the work.
That is why trains evolved from having only locomotive brakes, to having brake vans, to continous braking on all vehicles and now, with electric motors, propulsion throughout the whole train.
Electricity. The power will be supplied from the National Grid 400kV or 275kV network via feeder stations, which will be located along the route. See also https://www.railway-technology.com/news/hs2-hv-power-supply-systems/ from 15 months ago.How is the power generated, electric, diesel, hydrogen?

The trains will use a 25kV a.c. overhead system so that they can run on the WCML to destinations beyond HS2.How is the power generated, electric, diesel, hydrogen?
Thanks
Thank you Pedro! For me this is a great overview of the project, something I was aware of but not fully.
Amazing and looks VERY expensive!30,000 Lorry loads saved…
Pedro, I think green hydrogen is going to be a big part of out future. My employer, Cummins is a very large global engine manufacturer had installed hydrogen in Austrian National railways and working with France & Germany. As your article said it is very clean and in many cases can be backward compatible with diesels and the like!
Interest article and very well done. However I think the technology has passed the article by. What we can see is that many providers are taking multiple paths, and all technological shifts will take time to do what we eventually need.This will interest the hydrogen buffs but it doesn't look promising for a long time yet.
