Not if you do it simultaneously… cost is higher than just rail, but rains wouldn’t have range limits at all, and would weigh less, meaning less energy used to accelerate (and better emergency brake response).
I’m very pro EV, but even more a fan of distributed power systems that aren’t chemical based.
We can consider it a relatively straightforward upgrade to the system though. Definitely more expensive than upgrading individual trainsets to h2 or lithium, and nowhere near as quick… But it could be staged, or just the mainlines.
Imagine mainlines get electrified so EV or h2 trains use none of their onboard energy, until they start getting onto the unelectrified branches.
That’s exactly what New Zealand is doing with battery electric trains, the plan is for them to run on batteries once they get beyond the overhead line network, to service areas where it’s not worthwhile to have overhead lines.
Not with hydrogen trains though, that’s a dead end technology.
Again, not a fan of how the h2 is sourced, how limited its surrounding infra is, etc etc. Just saying that at least for trains, it makes more sense than for a car.
I do like that it’s approximately an EV that isn’t lithium constrained, but plenty of serious downsides as well, see: intra-atomic escape.
Overhead lines are almost as expensive as laying the track in the first place though.

That ship has, for the most part, sailed though.

I’m inclined to agree re: h2, though at least with trains it kinda could work, maybe. They tend to come back to similar yards all over the place.
Hydrogen cars is just… Don’t.
A hydrogen car is basically an electric car that is more expensive to run than an ICE vehicle, they’re an utterly moronic idea.
And there are actually EVs with more range than a hydrogen car, with far more options to charge.
