What enables the tram to drive backwards?
Show the correct answer
Correct answer
A. The reverser.
Explanation
In the photo you can see a tram driving over snow-covered tracks. Driving the tram backwards is made possible by the reverser - answer A.
The reverser is the switch for the direction of travel with the positions "P" (forwards), "T" (backwards) and "0" (neutral). Setting it to "T" changes the direction in which the motors work, so the tram can reverse. "Przestawiacz" (answer B, the reset switch) is not a control device of the tram, and the adjuster (answer C) is used to move the points by hand. When reversing, you exercise particular caution, and if there are difficulties you get help from another person. Before reversing, you check that the space behind the tram is clear.
