What effect does residual material on the tracks originating from wet leaves induce?
Show the correct answer
Correct answer
C. It increases the possibility of skidding.
Explanation
The question is about the substance formed from wet leaves lying on the tracks. It increases the chance of skidding - answer C.
Leaves crushed by the wheels of the tram form a thin, greasy layer on the rails, which is very slippery when damp. The grip of the wheels on the rails drops noticeably, so the wheels easily slip when moving off, and when braking they lock and the tram travels a longer distance. That is why this substance does not reduce the risk of skidding (answer A) and does not leave grip unaffected (answer B). In autumn, on sections with leaves, you drive more slowly, brake earlier and more gently, and use the sander if necessary.
