Where is the EMV exhaust located on an M-3 pair of cars?

The EMV exhaust on an M-3 pair of cars is located on the "A" car off the cab side, in the middle of the car, and it is situated outside only. This positioning is crucial as it allows for the safe discharge of exhaust gases outside of the train, preventing any buildup of harmful gases in the passenger compartment or cab area. The external placement also makes maintenance and inspections easier, ensuring that operators can verify its function without needing to access confined spaces. Understanding the correct location of safety and exhaust systems is vital for train operations, helping ensure the safety of both crew members and passengers on board.
