Answer 1

In railroad operations, cars on a grade must be under control for safe coupling, utilizing techniques and equipment to restrain movement.

Step-by-step explanation:

When coupling cars on a grade, safety requires that the cars moved in making the coupling MUST be under control. In the context of railroad operations, this typically means that the speed and movement of the rail cars must be closely monitored to avoid any collisions or accidents. Rail workers often use specific techniques and equipment to ensure that cars are coupled safely, as gravity on an incline can cause uncontrolled movement. Proper communication, signaling, and the use of hand brakes or other restraining devices are crucial for the safety of the workers and the integrity of the cargo.
