A buffer stop, bumper, bumping post, bumper block or stopblock (US), is a device to prevent railway vehicles from going past the end of a physical section of track. The design of the buffer stop is dependent, in part, on the kind of couplings that the railway uses, since the coupling gear is the first part of the vehicle that the buffer stop ...
The centre of the buffer on European railway vehicles must be between 940 and 1,065 mm above the top of rail. Spain was an exception for a long time. A buffer separation of 1,950 mm was specified there because of the force transmitted to the longitudinal beams of the wagons, which are further apart due to their broad gauge railways.
Narrow gauge flat wagons, 750 mm (2 ft 5 + 1 ⁄ 2 in).Note the single buffer with a hook on the right side and a chain on the other. On some narrow-gauge lines in Europe, and on the Paris Metro, a simplified version of the loose-coupler is used, consisting of a single central buffer with a chain underneath.
Trap points with a crossing are double trap points where the tongues of rail are longer, so that the trap point rail nearest the main line continues over the siding rail with a common crossing or frog. A trap road with stops is a short dead-end siding leading to some method of stopping a vehicle, such as a sand drag or buffer stop.
An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.
A railway ending in a locality (terminus) with no other rail services. Typically includes buffer stops at the end of the tracks.

A parking space commonly contains a parking chock (also known as a parking curb, parking bumper, wheel stop, parking chock, curb stop, bumper block, [2] and turtarrier [citation needed]), a barrier which is used to prevent cars from pulling too far into the space and obstructing an adjacent parking space, curb, or sidewalk.
The max bumper height for 4x4s is 25 inches. Bumpers must be at least 4.5 inches tall and must extend 10 inches outside of the frame rail. Bumpers must be attached in at least four places. Mississippi
