      I wonder if overhead wires make sense with the state of battery technology now? It must be cheaper to build battery-powered trains than install and maintain all that infra before you even factor in the cost of adjusting bridges and tunnels to accommodate the overhead wires.

        Unlikely. Batteries are still incredibly expensive, also heavy and a consumable item (need to be regularly replaced). Overhead wires don’t work for 1 train, but for all of them. They are also a mostly permanent installation with comparatively cheap maintenance (they are just steel+paint for the most part).

        It’s surely fine for a fringe route, where a train or two runs, and that would need electrification for a lot of track. So I’d assume there’s a break even point somewhere.

        What are you talking about?

        Batteries have planety of drawbacks compared to overhead wires.

        • Weight - Batteries way a LOT, meaning that locomotives need to be stronger, meaning they will be heavier, meaning that need stronger bridges and sturdier tracks.
        • Lifetime - Batteries are consumed as they are used and recharged, they are also not as easy/cheap to replace as pantographs.
        • Range - Batteries has limited range, normal electric trains have unlimited range.
        • Charge time - Batteries need charging, normal electric trains does not.

        Normal electric trains are technically the ideal transportation, you have unlimited range and don’t need to carry the fuel.

          Don’t forget acceleration, one of the main reasons passenger trains care about weight is that you can get up to and down from line speed quicker, thusly saving trip time and allowing for more frequency/capacity from the same number of trains and drivers.

          The extra weight from the batteries means you don’t get said benefits from going to battery electric as compared to overhead line.

    If only there was some way of having all these benefits without having to haul heavy batteries around…

    slashes fuel costs by up to 50 per cent

    And the cost of the battery will be recovered in… How many years?
