When can a tram driver increase the speed negotiating a curve of the road?
Show the correct answer
Correct answer
B. When the last carriage leaves the curve.
Explanation
The question is about the moment when you can increase the speed of the tram after going through a bend in the road. The tram driver may do this only when the last car has left the bend - answer B.
A tram is long, and on a bend every car is affected by centrifugal force. Accelerating while the rear part is still on the bend increases the risk of derailment, throws passengers around and speeds up wear of the rails and wheels. Accelerating when entering the bend (answer A) is particularly dangerous. The first car leaving the bend (answer C) is not enough, because the other cars are still travelling on the bend. Remember the length of your tram set and look in the mirror to check whether the rear of the tram is already on straight track.
