20-460: Khulna–Mongla Port line is a 65-kilometre long (40 mi)under-construction broad gauge railway to connect the country with Mongla Port . The Rupsha Rail Bridge is located on this route. In 2010, the government planned to build a railway from Khulna to Mongla Port . A budget of ৳1,721 crore was fixed for the construction of this railway, a joint financing of India and Bangladesh. But in 2015 it increased to ৳3,802 crores . The deadline for
40-563: A break-of-gauge with US railways, the War of 1812 still being a fresh memory. However, there is little supporting evidence for this, and this story appears to be traced to a single claim from the late 1800s. The Bay Area Rapid Transit system is the only operating railroad in the United States to use 1,676 mm ( 5 ft 6 in ) broad gauge, with 120 miles (190 km) of double tracked routes. The original engineers chose
60-688: A 27.1 km (16.8 mi) line of Lahore metro . In Sri Lanka, all services currently operate on 1,676 mm ( 5 ft 6 in ) broad gauge only. The 1,676 mm ( 5 ft 6 in ) broad gauge was first used in Scotland for two short, isolated lines, the Dundee and Arbroath Railway (1836-1847) and the Arbroath and Forfar Railway (1838-). Both the lines were subsequently converted to standard gauge . The Iberian-gauge railways , that service much of Spain and Portugal, have
80-642: A mix of 1,676 mm ( 5 ft 6 in ) broad gauge and metre gauge . The broad gauge network is primarily located to the west of the Jamuna River , while the metre gauge network is primarily located to its east. The Jamuna Bridge is a mixed-use bridge that contains a dual gauge connection across the river linking both networks. In Nepal, all services currently operate on 1,676 mm ( 5 ft 6 in ) broad gauge only. In Pakistan, all services currently operate on 1,676 mm ( 5 ft 6 in ) broad gauge only, except for
100-464: A track gauge of 1,668 mm ( 5 ft 5 + 21 ⁄ 32 in ), just 8 mm ( 5 ⁄ 16 in) different from 1,676 mm ( 5 ft 6 in ). Used rolling stock from Iberia has been employed on broad-gauge lines in Argentina and Chile. Canada became the first British colony, in the 1850s, to use 1,676 mm ( 5 ft 6 in ) broad gauge. It

You can help Misplaced Pages by expanding it . 5 ft 6 in gauge railway 5 ft 6 in (1,676 mm) is a broad track gauge , used in India , Pakistan , western Bangladesh , Sri Lanka , Argentina , Chile , and on BART in the San Francisco Bay Area . In North America, it is called Indian , Provincial , Portland , or Texas gauge . In Argentina and Chile, it
140-928: Is closely similar to the Indian gauge, with only 8 mm ( 5 ⁄ 16 in) difference, and allows compatibility with the rolling stock. For example, in recent years Chile and Argentina have bought second hand Spanish/Portuguese Iberian-gauge rolling stock. 1,668 mm trains can run on 1,676 mm gauge without adaptation, but for better stability in high-speed running a wheelset replacement may be required (for example, Russian-Finnish train Allegro has 1,522 mm or 4 ft 11 + 29 ⁄ 32 in gauge, intermediate between Russian 1,520 mm or 4 ft 11 + 27 ⁄ 32 in and Finnish 1,524 mm or 5 ft ). Backward compatibility—1,676 mm trains on 1,668 mm gauge—is possible, but no examples and data exist. Due to
160-663: Is known as "trocha ancha" (Spanish for "broad gauge"). In the Indian subcontinent it is simply known as "broad gauge". It is the widest gauge in regular passenger use anywhere in the world. In India , the initial freight railway lines were built using standard gauge . In the 1850s, the Great Indian Peninsula Railway adopted the gauge of 1,676 mm ( 5 ft 6 in ) for the first passenger railway in India between Bori Bunder and Thane . This
180-505: Is predominantly on 1,676 mm ( 5 ft 6 in ) broad gauge. Most links of 1,676 mm ( 5 ft 6 in ) broad gauge railways are in the center-south of the country. Only a few lines of the Ferrocarril del Sur (Southern Railroad Network) were 1,000 mm ( 3 ft 3 + 3 ⁄ 8 in ) metre gauge or 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ) standard gauge ,
200-698: The Matucana tunnel that connected Mapocho and the Central Station in Santiago . The Transandine Railway that connected both Argentinean and Chilean broad gauge networks through the Uspallata pass in the Andes mountains was actually a 1,000 mm ( 3 ft 3 + 3 ⁄ 8 in ) narrow gauge link. The Iberian gauge ( 1,668 mm or 5 ft 5 + 21 ⁄ 32 in )
220-559: The construction project was 2018. Due to the change in the route of the railway, the construction of a bridge over the Rupsa River became final and the length of the proposed railway increased from 53 km to 65 km. Two Indian contractors were appointed for the construction in 2015, but construction began the following year. As of November 2017, 27.5% of railway construction work was completed. The following year saw another 7.95% progress in construction. However, due to various complications,

#1732782919779240-605: The duration of the project by two more years. In 2023, the construction budget was proposed to increase by another ৳459 crore . As of March 2023, the construction of the railway line was 96% complete. According to the project officials, the construction of the railway can be completed in July of the same year. This line was opened in 1 November 2023. This Asia rail-related article is a stub . You can help Misplaced Pages by expanding it . This article about transport in Bangladesh
260-701: The notable exceptions being one of the few active links: the Ramal Talca-Constitución branch and the Metro de Santiago . On the contrary, just a few branches of the FCN (Ferrocarril del Norte) were broad gauge, most notably the Mapocho-Puerto mainline between Santiago and Valparaiso, the Santiago–Valparaíso railway line . This link was directly connected to the southern railroad network using
280-564: The railway could not be completed within three and a half years, due to which the deadline was proposed back to 2020. In 2019, Md. Nurul Islam Sujon , the railway minister of the country, announced that the railway line would be commissioned in 2022. On 25 June 2022, the construction work of the Rupsha Rail Bridge was completed. But in the same year, Bangladesh Railway sent a letter to the Ministry of Railways requesting to extend
300-843: The shape of BART wheels and rail has been modified since then ). This has complicated maintenance of the system, as it requires custom wheelsets, brake systems, and track maintenance vehicles. The New Orleans, Opelousas and Great Western Railroad (NOO&GW) used 1,676 mm ( 5 ft 6 in ) broad gauge until 1872, and the Texas and New Orleans Railroad used 1,676 mm ( 5 ft 6 in ) broad gauge ("Texas gauge") until 1876. The Grand Trunk Railway predecessor St. Lawrence and Atlantic Railroad which operated in Quebec , Vermont, New Hampshire and Maine also used 1,676 mm ( 5 ft 6 in ) broad gauge ("Canadian gauge", "Provincial gauge" or "Portland gauge" ) but
320-430: The wide gauge for its "great stability and smoother riding qualities" and intended to make a state-of-the-art system for other municipalities to emulate. The use of 1,676 mm ( 5 ft 6 in ) broad gauge rails was one of many unconventional design elements included in its design which, in addition to its unusual gauge, also used flat-edge rail, rather than typical rail that angles slightly inward (although
340-578: Was changed to standard gauge in 1873. The Grand Trunk Railway operated from headquarters in Montreal , Quebec, although corporate headquarters were in London , England . The St. Lawrence and Atlantic Railroad which operated in Quebec , Vermont, New Hampshire and Maine also used it but was converted in 1873. There is a longstanding rumour that the Provincial gauge was selected specifically to create
360-682: Was converted in 1873. Several Maine railroads connected to the Grand Trunk Railway shared its "Portland Gauge". The Androscoggin and Kennebec Railroad and the Buckfield Branch Railroad were later consolidated as the Maine Central Railroad which converted to standard gauge in 1871. John A. Poor's chief engineer Alvin C. Morton compiled the following advantages of "Portland Gauge" for Maine railways in 1847: The national railway network
380-537: Was known as the "Provincial gauge" in Canada. The earliest railways in Canada, including the 1836 Champlain and St. Lawrence and 1847 Montreal and Lachine Railway however, were built to 4 ft 8 + 1 ⁄ 2 in ( 1,435 mm ) standard gauge . The Grand Trunk Railway which operated in several Canadian provinces ( Quebec and Ontario ) and American states ( Connecticut , Maine , Massachusetts , New Hampshire , and Vermont ) used it, but
400-538: Was then adopted as the standard for the nationwide network. Indian Railways today predominantly operates on 1,676 mm ( 5 ft 6 in ) broad gauge. Most of the metre gauge and narrow gauge railways have been converted to broad gauge. Small stretches of the network that remain on metre and narrow gauges are also being converted to broad gauge . Rapid transit lines are mostly on standard gauge, although some initial lines use 1,676 mm ( 5 ft 6 in ) broad gauge. Bangladesh Railways uses
