EM-1 Train Stop

The train stop is used in conjunction with wayside signals in subway and urban transportation systems to ensure observance of, and compliance with, restrictive indications. Failure to comply with the rules regarding such indications results in stopping the train. Operation is completely automatic and entirely independent of any action on the part of the motorman. The system functions by means of mechanical contact between a wayside trip arm and a brake emergency trip switch or trip cock which is mounted on the car. The wayside trip arm is lowered when the signal is clear and raised when the signal is at stop. If a train tries to pass a signal at stop, the wayside arm will engage the cars brake emergency trip switch or trip cock, thereby initiating an emergency brake application.
