    Hmmm, I’m not sure I understand…

    A large explosion every second has units of power, not energy. So to me this is suggesting that the train is putting out power equal to its kinetic energy per second. That’s certainly not the case — it implies that the train is powerful enough to accelerate to the speed in 1s, which is definitely not true.

    But that’s just my interpretation.

      Yeah, I forgot that a large part of the energy is in inertia and not the pulling of the engine.
