How does the presence of leaves in the trackway affect the behaviour of the tram.
Show the correct answer
Correct answer
B. It reduces grip.
Explanation
The question is about how leaves on the tram tracks affect the behaviour of a tram. Leaves reduce grip - answer B.
Leaves crushed by the wheels form a slippery layer on the rails, especially when damp. The wheels lose grip, so the tram has more difficulty moving off, and when braking the wheels lock easily and the braking distance becomes longer. The claim that leaves have no effect (answer A) or increase grip (answer C) contradicts the experience of tram drivers - autumn is considered the most difficult time of year for driving a tram. On such sections, you reduce speed, increase the following distance from the tram in front, brake earlier and more gently, and use the sander if necessary.
