What do you use to change the position of the switch points in a mechanically-controlled railroad switch?
Show the correct answer
Correct answer
B. The adjuster
Explanation
In the photo you can see a tram driver who is moving the switch blade of the points with a metal bar. To change the position of the switch blade in mechanically controlled points, you use the adjuster (nastawiacz) - answer B.
The adjuster is a bar that you put into an opening next to the switch blade and use to move the blade to the other side. The reverser (answer A) is used to choose the direction of travel of the tram - forwards or backwards, and the master controller (answer C) is used to control the driving speed and braking. After moving the points, you check that the switch blade is resting against the stock rail, and you pass over slowly. Use the adjuster carefully, because the switch blade moves with great force.
