Is it necessary to reduce the speed of the tram when passing the rail switch?
Show the correct answer
Correct answer
B. Yes, it is mandatory.
Explanation
The question is about driving a tram through points (a switch). Reducing speed when passing through points is mandatory - answer B.
At points, the track splits, and the wheels pass over the switch blades and the crossing (frog), where a jolt can easily happen and, if a switch blade is in the wrong position, a derailment. At a low speed, you have time to stop the tram when you notice something wrong. The obligation is not limited to points marked with sign BT-4 (answer A) - before such points you even have to stop and check the position of the switch blade. Hurrying to leave a junction (answer C) does not justify driving fast through points, because a derailment would block traffic for a long time.
