2 ft 6 in (762 mm) gauge railways are narrow gauge railways with track gauge of 2 ft 6 in (762 mm). This type of rail was promoted especially in the colonies of the British Empire during the second half of the nineteenth century by Thomas Hall and Everard Calthrop.
Several Bosnian-gauge railways with 760 mm (2 ft 5+15⁄16 in) are found in south-eastern Europe. 760 mm (29.92 in) is well within tolerances of 762 mm (30.00 in).
A narrow-gauge railway is a railway with a track gauge narrower than standard 1,435 mm. Most narrow-gauge railways are between 600 mm and 1,067 mm.
OO9, often also denoted as 009 or 00-9 is a model railway scale and gauge combination of 4 mm scale and 9 mm gauge tracks, which models a prototype track gauge of 2 ft 3 in. It is a common choice in the United Kingdom for the modelling of narrow-gauge railways whose prototype gauges lie approximately between 2 ft and 2 ft 6 in. The 9 mm track gauge is used by N gauge model railways, a common commercial scale, which means that a selection of wheels, track, and mechanisms is readily available.
A transporter wagon, in railway terminology, is a wagon (UIC) or railroad car (US) designed to carry other railway equipment. Normally, it is used to transport equipment of a different rail gauge. In most cases, a transporter wagon is a narrower gauge wagon for transporting a wider gauge equipment, allowing freight in a wider gauge wagons to reach destinations on the narrower gauge network without the expense and time of transshipment into a narrower gauge wagons.
HOn30 gauge is the modelling of narrow-gauge railways in HO on N gauge track in 1:87 scale ratio.
This is a list of narrow-gauge locomotives that have been or are being operated by Indian Railways. All railways except the heritage ones are closed or under conversion/are converted to the nation-wide standard 5 ft 6 in gauge, under Project Unigauge. So narrow-gauge locomotives are operating only on the heritage routes as of 2021.
On30gauge is the modelling of narrow gauge railways in O scale on HO gauge track in 1:48 scale ratio by American and Australian model railroaders, in 1:43.5 scale ratio by British and French model railroaders and 1:45 by Continental European model railroaders.
The Kalka–Shimla Railway is a 2 ft 6 in narrow-gauge railway in North India which traverses a mostly mountainous route from Kalka to Shimla. It is known for dramatic views of the hills and surrounding villages. The railway was built under the direction of Herbert Septimus Harington between 1898 and 1903 to connect Shimla, the summer capital of India during the British Raj, with the rest of the Indian rail system.
Everard Richard Calthrop was a British railway engineer and inventor. Calthrop was a notable promoter and builder of narrow-gauge railways, especially of 2 ft 6 in narrow gauge, and was especially prominent in India. His most notable achievement was the Barsi Light Railway, but he is best known in his home country for the Leek and Manifold Valley Light Railway. Calthrop has been described as a "railway genius". Later in life he took an interest in aviation, patenting some early designs for parachutes.
Martin's Light Railways (MLR) consisted of seven narrow-gauge railway lines in the states of West Bengal, Bihar and Uttar Pradesh in India. The railways were built and owned by Martin & Co., which was a British company. Later, it was being operated by Indian government and was permanently shut down in 80's.
Bosnian-gauge railways are railways with track gauge of 760 mm. These were found extensively in the former Austro-Hungarian Empire as a standardised form of narrow gauge. The name is also used for lines of the same gauge outside Bosnia, for example in Austria. Similar track gauges are the 2 ft 6 in and 750 mm gauge.
The Satpura Railway was a 2 ft 6 in narrow-gauge railway in the states of Madhya Pradesh and Maharashtra in central India.
There are currently no operational railways in Cyprus,
Most Bosnian-gauge railway lines were built during the Austro-Hungarian Empire. Several 760 mm gauge railways were planned in order to link the extensive narrow-gauge railways in the Austro-Hungarian Empire with those in Bosnia and Herzegovina. Until the outbreak of the Balkan Wars in 1912 several were constructed.
Europe inherited a diversity of rail gauges. Extensive narrow-gauge railway networks exist in Spain, Central Europe and Southeastern Europe.
750 mm narrow-gauge railways are very similar to 760 mm and 2 ft 6 in gauge. 750 mm gauge rolling stock is almost compatible with 760 and 762 mm railways.
The Pune–Miraj–Londa line is an important railway line connecting Pune in Maharashtra and Londa in Karnataka. It covers a distance of 468 kilometres (291 mi) across Maharashtra and Karnataka. Of the total 468 km distance of this line, 280 km stretch falls under the jurisdiction of Central Railways and the remaining 188 km section under South Western Railway.
McLeod's Light Railways (MLR) consisted of following four 2 ft 6 in narrow-gauge lines in West Bengal in India. The railways were built and owned by McLeod & Company, which was the subsidiary of a London company of managing agents, McLeod Russell & Co. Ltd. On 1 July 1967, the Bankura Damodar Railway was merged with South Eastern Railway.
The Bardhaman–Katwa line is a 5 ft 6 in broad gauge branch line connecting Bardhaman and Katwa in Purba Bardhaman district of West Bengal. It is under the jurisdiction of Eastern Railway. The line was a narrow gauge line, before its gauge conversion began on 2010. The gauge conversion was done in two phases along with electrification and the full broad gauge line was thrown open for public again on 12 January 2018.
