Move quickly to the rear of the car. Look for a clearly marked emergency brake valve. Pull the handle to release brake air pressure so that the brakes engage.
Locate a crew member's radio and call for help in the event that the brakes don't stop or slow the train. Press "talk" on the radio. Give information about the train, location, destination and number.
Head to the front of the train. Pull all the emergency brake valves along the way or instruct other passengers to do so. Look for a wheel or lever in a vestibule just off the rear of the car and use it to tighten the brake valves.
Step across the locomotive coupler with caution. Look for clearly marked emergency valves in the engine room or on the left side of the engineer's cab. Push all the handles as far forward as possible.
Look for the white sliding switches on the engineer's control area. Slide them all down as far as possible to cut off electricity to the engine.
Listen for a lot of noise in the engine room that indicates the locomotive is still running. Move along the length of the engine block to the rear and find the same-color layshaft lever that is about 2 feet long. Pull the lever all the way down to shut down the engine.
Move back to the cab at the front of the locomotive. Sound the whistle, marked "horn," to alert other of the approach of the train while it takes 2 or 3 miles to come to a stop.
