ABSTRACT:
An emergency release handle is pivotally mounted within an interior wall of a railcar and connected to pull a cable under emergency conditions to actuate a mechanism, such as a mechanism to open a door. The handle is normally maintained inside the wall by a flexible guard plate and retaining screws passing through screw holes which are connected to the wall surface. Manual gripping means is connected to the handle to permit a person to grip it and pull to cause the flexible guard to flex and pass the retaining elements and permit the handle to pivot and pull the cable.
