What should a tram driver do after setting the tram in motion?
Show the correct answer
Correct answer
B. Speed up the tram to the desired speed, and drive as long as possible on the freewheel.
Explanation
This question is about driving after moving off. The tram driver should accelerate the tram to the desired speed and coast for as long as possible - the answer is B.
Coasting means the tram rolling without drawing current, using the energy stored while accelerating. The rolling resistance of a tram on rails is low, so coasting lasts a long time, and driving is economical and smooth. Switching the drive on repeatedly (answer A) causes jerks and increases energy consumption. Releasing the dead man's device (answer C) while driving triggers emergency braking, so it would be a serious mistake. You plan coasting so that you can start braking smoothly before a stop or junction.
