Will the rail brakes work after the failure of the converter?
Show the correct answer
Correct answer
A. Yes.
Explanation
The question is about whether the track brakes work after a converter failure. The track brakes will work - answer A.
Track brakes are electromagnetic and are pulled towards the rail when electric current flows through them. They are powered from the tram's batteries, not directly from the converter, so they also work after the converter fails - this is important, because they serve as a safety brake. Answer C is wrong, and answer B adds an unnecessary condition about power supply from the second car. However, after a converter failure the batteries are not being recharged, so the tram driver informs the traffic control centre (nadzór ruchu) and does not continue driving for longer than necessary.
