The eDumper makes a good case for going fully electric with heavy-duty construction, mining, and industrial equipment.

    I wouldn’t be surprised if there are electrified railway lines doing the same. Regenerate large amounts of energy into the grid while descending loaded; consume a relatively small amount of energy to haul the empty train back uphill.

      Paywall article, but this already exists in Australia for pretty much the same use case: https://www.railtech.com/rolling-stock/2022/03/04/australian-mining-company-works-on-infinity-train-using-gravity-to-regenerating-batteries/?gdpr=deny

      An early version of the Petřín ropeway in Prague used to contain tanks in both cars. The upper one would be filled with sewage collected rainwater from the city’s hilltop quarter and the energy of the descent was used to pull the other car up. Additionally, the way up cost twice as much so there was an incentive to ascend on foot, which was about as fast despite the incline.

      I don’t know about going downhill in general, but there are some that use regenerative braking (regular braking, on flat terrain) so maybe

      Most mines are underground so for most this can’t work, but where it does they are sure to use it.

        Regular trains don’t run underground. Lots of opencast mines exist .

        Basically all mines have an above ground terminal where whatever you mined is unloaded from your underground trains, lifts, haul trucks or whatever else onto storage piles, then loaded onto the actual long distance trains.

        If the mine entry is up a mountain, then the trip down from that point will be a net energy producer regardless of anything else.
