Answer: MU-2A Valve or Double- Ported Cutout Cock
Feedback:
On older locomotives, there is a physical valve called an MU-2A or Double-Ported Cutout Cock that controls the independent brake. The valve is usually located near the bottom of the control stand. On new CCB style locomotives, use the computer screens to cut in/cut out the independent brakes.
