Automatic Tri-Coupler

The Tri-coupler allows automatic connection of air and electrical train lines upon mechanical coupling of cars. Presently, these are connected manually by a brakeman stepping between cars to make the connections. Separation of air and electrical lines is automatic in both cases. 

 Goals:    

• Increase crew safety by eliminating manual air and electrical connections for air brake and Electrically Controlled Pneumatic (ECP) lines 
• Retains normal mechanical coupling 

Features:

• Provides normal mechanical coupling
• Provides automatic pneumatic coupling for airbrake system
• Provides automatic electrical coupling for ECP brake system
• Feedback on coupling status in ECP environment
• Overlays on existing equipment
•
