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
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.

How is the power generated, electric, diesel, hydrogen?
Thanks
 
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!
Great article!
