Not to say trains are not more efficient than cars, because they are for a myriad of reasons. But electric motors scale relatively linear to my extent of knowledge, so usually it just ends up being that trains use many motors instead of one big motor.

    Thanks for the info, I didn't know how exactly this works, but I was aware that this factor is different for each device.

    Thinking about it I guess that explains why small electric motor powered devices exist often while small combustion powered devices are rare? The only items I can come up with are forestry/gardening devices, tools for cooking and I guess lanterns. With the latter only using the heat/light and not actually moving anything.
