What setting of the reverser may cause the inability to drive a double-carriage tram?
Show the correct answer
Correct answer
B. In the first carriage the reverser is set to "P" and in the second carriage to "T".
Explanation
In the drawing you can see three settings of the reversers in a double-carriage tram. The inability to drive may be caused by setting the reverser in the first carriage to "P" and in the second carriage to "T" - answer B.
The reverser is the switch for the direction of travel: position "P" means driving forwards, "T" means driving backwards, and "0" is the neutral position, in which the tram does not move. In a two-carriage set, the tram is controlled from the first carriage, and the reverser in the second carriage should be at "0". Setting "T" in the second carriage with "P" in the first means opposite directions and makes driving impossible. Settings A and C are correct.
