    You are aware that electric trains also use electric motors, just like electric cars do, right? And you are aware that electric cars rely on an electric battery while electric trains rely primarily on overhead electric power lines, are you?

    That means cars require one extra component and an extra conversation of energy which trains don’t need. Every conversation of energy reduces efficiency of the final outcome. The more conversations, the less efficiency.

    Trains use: power lines -> electric motor
    Cars use: power lines -> electric battery -> electric motor

    Furthermore, bigger machines can be built to be more efficient than smaller ones. So bigger motors can use (electric) fuel more efficiently than smaller motors.
