  Overhead lines are almost as expensive as laying the track in the first place though.

    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.

      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.
