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.
The European network has traditionally been formed of many independent national railway networks with buffer and chain used near universally to allow the interchange of rolling stock. The European Union Technical Specifications for Interoperability (TSIs) for high-speed passenger rolling stock mandate the use of Scharfenberg Type 10 -compatible ...
A pneumatic buffer with sections cut away. A buffer is a part of the buffers and chain coupler system used on the railway systems of many countries, among them most of those in Europe, for attaching railway vehicles together (in North America, rolling stock instead has draft gear built into the couplers).
The Norwegian coupler allows sharper curves than the buffer and chain coupler, which is an advantage on narrow gauge railways where low speeds and reduced train loads allow a simpler system. The Norwegian coupler is found only on narrow gauge railways of 1,067 mm ( 3 ft 6 in ), 1,000 mm ( 3 ft 3 + 3 ⁄ 8 in ) or less in Great Britain and its ...
The C-AKv is a fully automatic coupler design, also known as the Faiveley Transpact; it is a hybrid compatible with both buffers and chain couplers and Russian SA3 couplers, intended as an option for the long delayed EU transition to center buffer couplers.
No chain is provided on dual-coupled vehicles, since the chain on the other vehicle can be used when the knuckle coupler is out of the way (down). 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.
For a line with a maximum speed of 60 km/h (37 mph), buffer-and-chain couplers increase the minimum radius to around 150 m (164 yd; 492 ft). As narrow-gauge railways , tramways , and rapid transit systems normally do not interchange with mainline railways, instances of these types of railway in Europe often use bufferless central couplers and ...
In 2009 the National Model Railroad Association convention at Fort Wayne hosted workshops demonstrating the use of SimSig for model rail simulations. [20] The information in the Edinburgh simulation has been referenced by the Rail Action Group, East of Scotland (RAGES) in discussion with the railway authorities and has been noted in their ...
