When performing a single car securement, test that the hand brake on the car to be set out is applied. Once applied, the car must be bled off or the brakes released. What is the next step in the process?
Move the car a sufficient distance to ensure hand brake is operational.
Have the conductor close the angle cock on the engine and then uncouple from the car.
Make a 20-psi brake pipe reduction and then move the car a sufficient distance.
Have the conductor block the wheels, and then uncouple from the car.
Answer: Move the car a sufficient distance to ensure hand brake is operational.Feedback: When a single car that has more than one hand brake is set out, all hand brakes must be applied. Moving the car a sufficient distance can be done using a pushing or pulling movement. Look for signs that the brake shoe is pressing against the braking surface. This should result in limited wheel rotation and adhesion to the rail.
