Comment on Swiss hydrogen-powered train sets 1741-mile record for nonstop travel

I’m very pro EV, but even more a fan of distributed power systems that aren’t chemical based.

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

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.

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.
