ABSTRACT:
A safety device for automatically actuating the air brake system for an entire train of railroad cars when any one or more of the cars becomes derailed includes a derail wheel on its own axle attached to the truck frame between the wheels both on the front and rear set of wheels which are nearest to the train line and normally, such derail wheel is spaced slightly above the rail but will engage the ground in a derailment causing it to rotate. A flexible cable is secured at one end to the axle of the derail wheel so as to be windable thereon when such wheel rotates and has its other end preferably connected to the nearest air hose coupling that is attached to a like coupling on an adjacent car. The winding up of the cable on the derail wheel assembly in a derailment acts to pull the air hose coupling loose from its coupling with the air hose on an adjacent car and the resulting breaking of the train line sets the brakes for all cars in the train. In a second embodiment, one end of the cable is detachably connected to an air valve placed in the air pipe of the train line whereby the winding of the cable opens the valve to break the train line and is then automatically disengaged from such valve to avoid damage thereto.
