Automatic Tri-Coupler

Tri-coupler

The Tri-coupler allows automatic connection ofair 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:

Tri-coupler

  • 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
