Compare non-adhesion drive systems(Linear Metro) and adhesion drive systems(conventional subway)

Non-adhesion drive system

The attraction and repulsion of linear motor magnets drive the car.

Diagram of the Non-adhesion drive system

Adhesion drive system

The friction between the wheels and rails drives the car.
Since the wheels are rotated by electric motors, excessive rotating force causes the wheels to slip.
