Question

The cars are equipped with a coupling arrangement similar to the one on railroad cars. What is the purpose of this coupling arrangement?

1) To connect the cars together
2) To provide stability to the cars
3) To allow for easy separation of the cars
4) To control the speed of the cars

Answer 1

The coupling arrangement on cars is designed primarily to connect the cars together, ensuring they move as one unit and providing stability to the convoy.

Step-by-step explanation:

The purpose of the coupling arrangement on cars, similar to that on railroad cars, is primarily to connect the cars together. This connection allows the cars to move as a unit, thereby transferring forces effectively between them and maintaining the integrity of the train. Additionally, these couplings provide stability to the convoy and do allow for easier separation when needed, such as for maintenance or reconfiguration of the train composition. However, controlling the speed of the cars is not a function of the coupling system; speed is regulated by the engine and the train's braking system.
