The difference is, that the rotor is allowed to move, and they’re switching coils in the stator to keep it going.

In this system, the force pulling the magnet towards the truck is being negated by the arm fixed to the truck.

If you placed a bunch of electromagnets on the guard rail, that would be more like a motor (technically, a linear motor,)
