Center buffer coupling on the Saxon narrow-gauge railways. With centre buffer couplings, the tasks of buffers are usually transferred to the coupling elements, which are designed to be correspondingly stable and are mounted with interposed spring elements within the vehicle frame instead of on a buffer beam. They are often used on narrow gauge ...
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.
A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge narrower than 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge. Most narrow-gauge railways are between 600 mm ( 1 ft 11 + 5 ⁄ 8 in ) and 1,067 mm ( 3 ft 6 in ).
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 ...
Johnston link-and-pin from 1873 to 1927 on Cape gauge, from 1906 on 2 ft (610 mm) narrow gauge in Natal. [23] [24] Bell-and-hook from 1902 on 2 ft (610 mm) narrow gauge in the Cape of Good Hope. [24] [25] AAR knuckle wide use from 1927 on Cape gauge. The first application of these couplers in what is now South Africa was in 1904 by the ultra ...
Track gauge or rail gauge (also known as track gage in North America [8]) is the distance between the inner sides (gauge sides) of the heads of the two load bearing rails that make up a single railway line. Each country uses different gauges for different types of trains.

The Norwegian coupling was developed in Norway about 1870, when the main railway network was built to 1067 mm (3 ft 6 in) narrow gauge. During the 20th century, these lines were rebuilt to 1435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge or closed. Since the rolling stock needed to be replaced, a change was made to buffers and chain couplers.
