Locomotive Parking Brakes
Before automated hand brakes/parking brakes, setting manual brakes required great physical effort. The brake operator had to use 125 pounds of force on the brake wheel or handle in order to set the brakes.
The use of automatic electrical braking systems, implemented in the mid-1990s, eliminated this challenge and guarantees that the brakes are set properly regardless of the operator's strength.
Automatic brakes also provide computer feedback to a locomotive's control system. If the brake is not released properly, the computer will prevent the locomotive from moving. Moving locomotives when the parking brake is set can damage the wheels.
