What is the correct position for the automatic brake valve cutout valve on the trailing locomotives?

The correct position for the automatic brake valve cutout valve on the trailing locomotives is "Out." When the cutout valve is in the "out" position, it allows the air brake system to be fully operational and for the automatic brakes to function correctly on the locomotive. This is particularly important because trailing locomotives can sometimes experience a lack of control over their brake functions if the cutout valve is inadvertently left in a different position.

Properly using the cutout valve is crucial for maintaining communication and functionality within the air brake system, especially when multiple locomotives are connected. If the valve were in a position that hampers the system, such as "In," it would prevent automatic braking operations, posing a safety risk. Therefore, ensuring that the cutout valve is "Out" guarantees that the automatic braking system is ready to respond as needed while the train is in motion.
