Abstract: Embodiments relate to a damping system, and in particular a clutch mechanism for an extended travel draft gear having components arranged such that movement of clutch mechanism components transforms kinetic energy into thermal energy via friction, while allowing for an extended length of travel. An arrangement of clutch component geometries, lengths, angles, etc. allows for motion along a longitudinal axis of the clutch mechanism to be damped via energy dissipation.

Abstract: Disclosed is a hopper car gate assembly including a frame configured for attachment to a hopper car body. The frame defines an opening and includes a beam, wherein the beam has a slot formed therein. A stop plate is removably attached to the beam to selectively obstruct the slot. The assembly has a door supported by the frame. A stop block is attached to the door, wherein the stop block is located on the door such that when the door is inserted into the frame the stop block is aligned with the slot. With the stop plate attached to the beam, the stop block engages with the stop plate to define an open position and prevent further movement of the door in the open direction. With the stop plate detached from the beam, the stop block passes through the slot to allow removal of the door from the frame.

Abstract: Embodiments relate to a railcar damping system configured for placement in a railcar center sill having longitudinally spaced stops defining a center sill pocket. The system includes a damping assembly configured for receiving and dissipating external forces acting on a coupler connected to the damping system. Various embodiments of the damping system include a longitudinally moveable member, at least one stop and at least one follower block. Some embodiments include a housing. The shape, positioning, and configurations of these features allow for differentiated travel between buff and draft movements.
