When the handle is placed in the handle off/continuous service position, what occurs?

When the handle is placed in the handle off/continuous service position, the critical function performed is the reduction of both equalizing reservoir and brake pipe pressure at a service rate. This action is essential for managing the train's braking system during normal operation. By reducing the pressures in these key components, the brakes on the train are applied gradually and in a controlled manner, which allows for smoother deceleration and helps prevent abrupt stops that could lead to safety issues or damage to the train.

This serviceable action ensures that the train can be brought to a stop without causing excessive strain on the braking system or the track infrastructure. It's important to note that this position is distinct from positions that apply the brakes at emergency rates or release the brakes, which are designed for different operational objectives. The focus on controlling pressure in both key reservoirs ensures optimal performance of the braking system and enhances train handling capabilities.
