Abstract: ABSTRACT OF THE DISCLOSURE      A pneumatic vigilance monitoring system which requires an engineer of a moving train to cycle an acknowledging valve within a predetermined time after the sounding of a warning whistle.  The system includes a pair of parallel control circuits each having a first choke and reservoir and a second reservoir and choke connected to the acknowledging valve.  A double check valve connects the second reservoirs to the warn-ing whistle as well as to a piloted three-way valve which normally causes a brake application valve to release the brake and which causes the brake application to initiate a penalty brake application if the locomotive engineer fails to periodically cycle the acknowledging valve.

A number of shafts are mounted to the frame below the lower filter plate and extend past opposite sides of the filter.  Elongate crank arms and eccentri-cally positioned tie rod connection pins are secured to the ends of the shafts.  The upper ends of the tie rods are mounted to opposite sides of the upper filter plate.

A locking arm is mounted to one of the shafts and is positioned to engage locking re-cesses in upper and lower locking dogs when the upper filter plate is fully opened and fully closed.  The locking dogs are are biased to normally engage the lock-ing arm and are selectively pivoted away from the actu-ator axis to release the locking arm when the filter is being opened or closed.
