Buffers and chain couplers (or couplings) – also known as "buffers and screw", "screw", and "screwlink" – are the de facto International Union of Railways (UIC) standard railway coupling used in the EU and UK, and on some railways in other parts of the world, such as in South America and India, on older rolling stock.
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.
By swapping the pulling and pushing devices, the standard screw coupling used on standard gauge railroads became a center buffer coupling with one screw coupling on each side of the buffer. The screw couplers are connected to a compensating lever that pivots on a vertical trunnion on the center buffer rod, allowing an even distribution of ...
A chair screw (also known as coach screw [16]) is a large (~6 in or 152 mm length, slightly under 1 in or 25 mm diameter) metal screw used to fix a chair (for bullhead rail), baseplate (for flat bottom rail) or to directly fasten a rail. Chair screws are screwed into a hole bored in the sleeper. [17]
Inter-stock coupling was with the automatic coupler (with the buffers retracted), while connection to the locomotive was with the buffer-and-chain system with a screw coupler. Today this dual coupling system has been adopted for all loco-hauled passenger trains in Great Britain to allow faster shunting operations.
A headstock of a rail vehicle is a transverse structural member located at the extreme end of the vehicle's underframe. The headstock supports the coupling at that end of the vehicle, and may also support buffers, in which case it may also be known as a buffer beam. [1] The headstocks form part of the underframe of a locomotive or a railroad car.
The agency which oversees rail operation regulations and safety requirements for U.S. freight, passenger and commuter rail operations [104] Filet Converting a double-stack container train to single stack by removing the top layer of containers, allowing the rest of the train to proceed along track that lacks double stack clearance.
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 ...
