How many EP cutouts are present per car on an M-3 married pair?

On an M-3 married pair, there is one EP (Emergency-Parking) cutout per car. This is an essential feature in the design and operation of the air brake system, as it allows for the isolation of the emergency brake function in case of a malfunction or when maintenance is required. Each car in the married pair contributes to the overall operation of the braking system, but the setup includes one dedicated EP cutout that serves specific operational and safety functions for each car. This design simplifies troubleshooting and maintenance tasks, ensuring that train crews can quickly address issues without multiple cutouts complicating the system.
