What position should the automatic brake valve handles be in on the trailing locomotives?

The correct position for the automatic brake valve handles on trailing locomotives is in Continuous Service. This setting ensures that the brakes on those locomotives are ready to operate smoothly in coordination with the rest of the train. When the automatic brake valve handles are set in Continuous Service, they allow for the gradual application and release of the brakes, which is essential for controlled train handling, especially during operations such as stopping at stations or reducing speed.

When set in Continuous Service, the system maintains the brake pressure in a manner that is conducive to smooth operation and minimizes the risk of abrupt braking that could lead to instability. This is crucial for maintaining the safety and integrity of train operations, particularly in longer trains where synchronization between the locomotives and trailing cars is vital. If the handles were in Off or Emergency positions, the brakes would either be released or applied suddenly, potentially leading to safety issues, while the Handbrake is not utilized in conjunction with the automatic braking system for regular operations.
