The title of this post, is the same as that of this article on Network Rail.

These are the first two paragraphs.

Network Rail and Vivarail today announced that Vivarail's next-generation battery train will be launched at COP26 and will run daily services throughout the international climate change conference.

This zero-emission train uses new batteries, developed by Vivarail, to combine maximum range with the ability to recharge quickly. The result is a train that can travel for up to 80 miles on battery power and recharge in only 10 minutes using Vivarail's patented Fast Charge system.

That is an excellent range coupled with a fast turnround time.

How will other companies like CAF, Hitachi and Stadler respond?

If all battery-electric trains can reach this range, I don't think we'll need hydrogen for multiple units, but we will probably need it for freight and other locomotives.
