Narrow-gauge railway in the context of "Radebeul"

The Hejaz railway (also spelled Hedjaz or Hijaz; Arabic: سِكَّة حَدِيد الحِجَاز sikkat ḥadīd al-ḥijāz or Arabic: الخَط الحَدِيدِي الحِجَازِي, Ottoman Turkish: حجاز دمیریولی, Turkish: Hicaz Demiryolu) was a narrow-gauge railway (1,050 mm / 3 ft 5+11⁄32 in track gauge) that ran from Damascus to Medina, through the Hejaz region of modern-day Saudi Arabia, with a branch line to Haifa on the Mediterranean Sea. The project was ordered by Sultan Abdul Hamid II in March 1900.

It was a part of the Ottoman railway network and the original goal was to extend the line from the Haydarpaşa Terminal in Kadıköy, Istanbul beyond Damascus to the Islamic holy city of Mecca. However, construction was interrupted due to the outbreak of World War I, and it reached only to Medina, 400 kilometres (250 mi) short of Mecca. The completed Damascus to Medina section was 1,300 kilometres (810 mi). It was the only railway completely built and operated by the Ottoman Empire.

An elevated railway or elevated train (also known as an el train or el for short) is a railway with the tracks above street level on a viaduct or other elevated structure (usually constructed from steel, cast iron, concrete, or bricks). The railway may be a broad-gauge, standard-gauge or narrow-gauge railway, rapid transit, light rail, monorail, or a suspension railway. Elevated railways are normally found in urban areas that would otherwise require impracticably many level crossings. Usually, the tracks of elevated railways that run on steel viaducts can be seen from street level.

The Newfoundland Railway was a narrow-gauge railway that operated on the island of Newfoundland from 1898 to 1988. With a total track length of 906 miles (1,458 km), it was the longest 3 ft 6 in (1,067 mm) narrow-gauge system in North America.

British Railways (BR), which from 1965 traded as British Rail, was a state-owned company that operated most rail transport in Great Britain from 1948 to 1997. Originally a trading brand of the Railway Executive of the British Transport Commission, it became an independent statutory corporation in January 1963, when it was formally renamed the British Railways Board.

British Railways was formed on 1 January 1948 as a result of the Transport Act 1947, which nationalised the Big Four British railway companies along with some other (but not all) smaller railways. Profitability of the railways became a pressing concern during the 1950s, leading to multiple efforts to bolster performance, including some line closures. The 1955 Modernisation Plan formally directed a process of dieselisation and electrification to take place; accordingly, steam locomotives had been entirely replaced by diesel and electric traction (except for the narrow-gauge Vale of Rheidol Railway tourist line) by 1968. On 1 January 1963, the British Railways Board was created to manage the railways as a successor to the British Transport Commission.

Metre-gauge railways (US: meter-gauge railways) are narrow-gauge railways with track gauge of 1,000 mm (3 ft 3+3⁄8 in) or 1 metre.

Metre gauge is used in around 95,000 kilometres (59,000 mi) of tracks around the world. It was used by several European colonial powers including France, Britain and Germany in their colonies. In Europe, large metre-gauge networks remain in use in Switzerland, Spain and many European towns with urban trams, but most metre-gauge local railways in France, Germany and Belgium closed down in the mid-20th century, although some still remain. With the revival of urban rail transport, metre-gauge light metros were built in some cities. The slightly-wider 1,009 mm (3 ft 3+23⁄32 in) gauge is used in Sofia, Bulgaria. Another similar gauge is 3 ft 6 in (1,067 mm).

Nalaikh (Mongolian: Налайх [naɮɛ́χ]) is one of nine districts of Ulaanbaatar. It has an area of 68,700 hectares and a population of 39,579 in 2022 (26,529 in 2005). A former coal-mining town, it consists of Shokhoi, Arjanchivlan, the Terelj holiday center, and other residential areas, as well as a former Soviet military cantonment, including an airfield.

Nalaikh is linked to Ulaanbaatar by a 43-kilometer narrow-gauge railway line, built in July 1938. The line had three stations (Nalaikh; Amgalan, a Ulaanbaatar suburb; and Kombinat, the city's industrial combine) and operated 14 steam locomotives, 16 passenger carriages, 70 goods wagons, 10 platform wagons, and nine fuel tank wagons. Nalaikh now has a broad-gauge branch line (via Khonkhor) to the Trans-Mongolian Railway. The Kapitalnaya shaft went into operation in 1951, and at full capacity produced 600,000 metric tons of coal a year. Nalaikh gained town status in 1962, and was established as a district of Ulaanbaatar in 1992. Since the closure of the coal mine in the 1990s, the district has had a high rate of unemployment.

Decauville (French: [dəkovil]) was a manufacturing company which was founded by Paul Decauville (1846–1922), a French pioneer in industrial railways. Decauville's major innovation was the use of ready-made sections of light, narrow-gauge track fastened to steel sleepers; this track was portable and could be disassembled and transported very easily.

The first Decauville railway used 400 mm (15+3⁄4 in) gauge; Decauville later refined his invention and switched to 500 mm (19+3⁄4 in) and 600 mm (1 ft 11+5⁄8 in) gauge.

Montreux railway station (French: Gare de Montreux) is the largest of the railway stations serving the municipality of Montreux, in the canton of Vaud, Switzerland.

All of the SBB-CFF-FFS standard gauge passenger trains operating on the Simplon line call at this station, which is also the western terminus of the GoldenPass Line narrow gauge railway lines to Zweisimmen and to Rochers de Naye.
