Where is the EMV located on an M-7 pair of cars?

The Emergency Manual Valve (EMV) on an M-7 pair of cars is indeed located inside both the A and B cars, specifically behind the L-1 door. This placement ensures that the valve is easily accessible to crew members during emergency situations, facilitating quick and effective operation. The location behind the L-1 door allows for rapid intervention, which is critical for maintaining safety during any operational issues. It's important for train crews to be familiar with this location to respond promptly to emergencies, ensuring passenger safety and the smooth operation of train services.

The design of the M-7 cars emphasizes accessibility and functionality, placing important safety equipment like the EMV in positions that are both convenient and logical for the crew to access while managing the train's operations.
