How can a tram driver adjust the braking force of the rail brakes?

Explanation

Correct answer: It has no effect on regulating the braking force of the brakes.

Track brakes are emergency brakes which operate on an "on/off" (all-or-nothing) principle. When activated by the tram driver, the electromagnets are drawn to the rail head with a maximum, predefined force. Consequently, the tram driver is unable to regulate their braking force and can only switch them on or off.
