An uncoupledmotor car, therefore, cannot be operated with itsswitches closed (exposed electric coupler contact pointsalive) due to the fact that the pipes of the air-brakesystem are open. An ingenious modification of the standard H. B. life-guard tripping gate permits its ready removal by a for-ward swing and lifting the engaging hooks from thesuspension rod. This is necessary on the coupled endof the motor car to permit lateral swing of the coup-lers on TRAIN WITH CENTER-ENTRANCE TRAILERS.
