Answer: Out
Feedback:
It's important to be in the Out position on trailing locomotives to ensure that only one automatic brake valve is cut in per locomotive consist. The air brakes on the entire train will not work properly if a trailing locomotive in a consist does not have the brake valve in the Out position.
