Show the correct answer
Correct answer
C. 100 mm.
Explanation
In the photo you can see the front of a tram with the lifeguard (obstacle deflector) placed just above the rails. The lower edge of the lifeguard should be no higher than 100 mm above the rail head - answer C.
The lifeguard pushes obstacles off the track, for example stones or branches, before they get under the wheels, and in an accident it makes it harder for a person to be pulled under the tram. To do this job, it must be low above the rail. The regulations require the lifeguard to be placed no higher than 100 mm above the rail head of an unloaded tram, so distances of 150 mm (answer A) and 120 mm (answer B) are above this limit. Before leaving, you check that the lifeguard is not damaged or bent. This measurement is checked by the technical staff.
