And I thought they were supposed to be shying away from fossil fuels.

    I cant find a source for your claim, the best I could find Was that they can be more efficient under circumstances than diesel mechanic Systems. But it seems to be at least close. Do you have a source you can link?

    The reasons theyre the choice number one are different. The Main reason, it doesnt have a Transmission and is easier to repair, while there’s also less parts that can break.

      I’m not claiming that electric transmission is more efficient always because it isn’t. But as you say it is close.

      In a scenario where a train drives at a constant speed forever, attaching the engine to the wheels directly is a clear winner.

      However, with varying torque requirements, an ICE can’t always operate at maximum efficiency. They are especially bad at starting from a standstill. You can get a good overview of the concept from this wiki article. https://en.m.wikipedia.org/wiki/Power_band

        You arent, but that’s how the discussion started and why I joined that discussion.

        Ive earned quite a bit though, because I was not entirely correct myself.
