Here in Europe they just run on electric cables.

You can almost make the case that overhead electrification is too expensive to implement in some places. I'm not totally sold on that math, but I keep hearing there are niche cases for hydrogen.

That mostly due to us freight rail being very focused on tight margins. That's why even in very dense rail areas they still use diesel trains.

I was talking specifically about European applications. US passenger rail is a disaster regardless of power source for legal, logistical, political, and social reasons. It's really sad. I like having my car as much as any other suburbanite, but I've seen good passenger rail systems around the world, and they're really nice to have.

In Europe you have an extensive electrified passenger network that’s easy to supply with electrical facilities due to a general lack of remote areas.

Many rail networks in the world have these areas where it is incredibly expensive to install electricity and they also don’t have the privilege of having invested in electrification for a century. There’s really not a good way to just electrify part of a network if mainlines are going through areas where electrical rolling stock can’t/won’t be served.
