What should you remember before you go about pushing tram carriages damaged due to a collision?
Show the correct answer
Correct answer
B. To discharge the brake release in the damaged carriage.
Explanation
In the photo you can see two trams standing close to each other on snow-covered tram tracks. Before you start pushing a tram set damaged in a collision, you must remember to operate the brake release devices (luzowniki) in the damaged carriage - answer B.
Operating the brake release devices means releasing the shoe brakes by hand. If the brakes of the damaged carriage stay applied, it cannot be pushed, and the wheels and brake linings will be destroyed. The hazard warning lights in the first set (answer A) are not the key thing here, and seating the passengers (answer C) does not matter, because the passengers are taken off before pushing. You push very slowly. Also remember that the brakes of the damaged carriage will not work then.
