Abstract
A railroad freight car may have external fittings, such as trackside-accessible ladder fittings that permit personnel to climb onto the decks and walkways of the car. Several embodiments of movable ladder assemblies are described that provide an extended or deployed or raised position of a handhold, and a retracted or lowered, or stored position. In other embodiments, the assembly is provided with a compliant member that allows the handhold resiliently to flex when encountered by solid objects such as shipping containers.
