After making a station stop on level track, what position should the brake valve handle be in while waiting for an indication light?

When waiting for an indication light after making a station stop on level track, the brake valve handle should be in the release position. This allows the train to remain in a state where it can easily resume movement, ensuring that the brake system is not unnecessarily engaged.

Maintaining the brake valve in the release position establishes that brakes are not applied, facilitating a quick return to operations once the indication light signals readiness to proceed. Being on level track means there is less risk of unintended train movement, but having the brakes released ensures smooth and efficient handling when it's time to start again.

In contrast, other positions such as emergency or applied would unnecessarily keep the train immobilized, which is not ideal while waiting for clearance. The neutral position could lead to some uncertainties in the state of the brakes, which is why release is the most straightforward and effective choice in this context.
