Which of the mentioned braking systems should a cable car be equipped with?
Show the correct answer
Correct answer
B. Service brake
Explanation
The question is about the braking systems that every tram in service should be equipped with. Every tram in service should have a service brake - answer B.
The service brake is used for normal reduction of speed and stopping the tram while driving, which is why it is the basic braking system. The rules on the technical conditions of trams also require other brakes - the emergency brake, the parking brake, the safety brake and the sudden-braking brake - but without a working service brake the tram must not run. The "electric" brake (hamulec "sieciowy", answer A) is not a separate braking system of a tram. The handbrake (answer C) is not the name of a system required in every tram in service - it is only a way of operating some of the brakes.
Legal basis: § 16 para. 1 of the Regulation of the Minister of Infrastructure of 2 March 2011 on the technical conditions of trams and trolleybuses and the scope of their necessary equipment (Dz.U. nr 65 poz. 344)
