The angle cock, one on each end of all cars and locomotives, connects the train line air between cars. Remote operation from the side of one car or the locomotive cab is envisioned. 

Goals:

• Increase crew safety by eliminating the need for manual operation of angle cocks
• Retain normal manual angle cock operations

Features:

• Push-button or remote, automatic angle cock operation
• Permits manual override
• Overlays on existing equipment
• Positive feedback of unit status
