A single-track railway is a railway where trains traveling in both directions share the same track. Single track is usually found on lesser-used rail lines, often branch lines , where the level of traffic is not high enough to justify the cost of constructing and maintaining a second track .

39-511: The Bittern Line is a railway branch line in Norfolk , England, that links Norwich to Sheringham . It passes through the Broads on its route to an Area of Outstanding Natural Beauty on the north Norfolk coast. It is named after the bittern , a rare bird found in the reedy wetlands of Norfolk. The line is 30 miles 22 chains (48.7 km) in length and there are 10 stations. It

78-459: A "reserve" track that can allow a reduced capacity service to continue if one track is closed. If a single-track line is designed to be used by more than one train at a time, it must have passing loops (also called passing sidings or crossing loops ) at intervals along the line to allow trains running in different directions to pass each other. These consist of short stretches of double track, usually long enough to hold one train. The capacity of

117-553: A certain industrial site such as a power station either because of a location away from the main line or to reduce congestion. They were typically built to lower standards, using lighter rail and shallow roadbeds when compared to main lines. Much of Canada's branch line history relates to large rail transport conglomerates (such as the Grand Trunk , Canadian National , or Canadian Pacific ) which would acquire formerly independent short line railways for use as branch lines, with

156-411: A larger yard, where these railcars are sorted and dispatched in larger trains with other cars destined to similar locations. Because industrial spurs generally have less capacity and traffic than a mainline, they tend to have lower maintenance and signaling (train control) standards. Before the rise of the long-distance trucking in the early 1930s, railroads were the primary means of transportation around

195-662: A section of the Midland and Great Northern Joint Railway line. From the early twentieth century until the end of steam services, in 1962, the Great Eastern Railway operated coastal holiday services from London Liverpool Street under names such as the Norfolk Coast Express and The Broadsman . Following the closure of the majority of the Midland and Great Northern network, the line operated as

234-823: A section of the West Rail line . Discontinued services include the Sha Tau Kok Railway and the Wo Hop Shek Branch . A spur line to Siu Sai Wan has been proposed. Delhi On the Delhi Metro , the Blue Line has a Branch Line with 8 Stations, linking Yamuna Bank to Ghaziabad via Anand Vihar ISBT and terminating at Vaishali. The first section of the Branch opened on 8 January 2010 with Anand Vihar as its terminal with six stations. It

273-459: A single branch between Norwich and Melton Constable before the section between Sheringham and Melton Constable was closed in 1964. The remainder of the line was listed for closure in 1967 but survived the proposal after being declined by the Secretary of State for Transport . The Bittern Line Partnership was set up by Norfolk County Council in 1997. and was designated a community rail line by

312-491: A single track, the journey is 0.8 miles (1.3 kilometres) long and the train takes around two and a half minutes to complete its journey. In North America, little-used branch lines are often sold by large railroads to become new common carrier short-line railroads of their own. Throughout the United States and Canada, branch lines link smaller towns too distant from the main line to be served efficiently, or to serve

351-624: A single-track line is determined by the number of passing loops. Passing loops may also be used to allow trains heading in the same direction at different speeds to overtake. In some circumstances on some isolated branch lines with a simple shuttle service (such as the Abbey Line in Great Britain or L202 railway in Croatia) a single-track line may work under the "one train working" principle without passing loops, where only one train

390-541: A single-track railway to double track is called duplication or doubling; converting double track to single track is known as singling. A double-track railway operating only a single track is known as single-line working . Kirkby railway station (until 1977) and Ormskirk railway station (until 1970) were double-track railway , when they were converted into single-track railway with cross-platform interchange . Building bike trails on rail corridors has occurred in limited examples; however, developing rail rights of way for

429-531: A subsidy for grain transport, and instead allowed railways to absorb branch line subsidies freely without making effort to improve the profitability of the lines. The term "grain-dependent branch lines" began being used as early as 1978 to refer to the special case of these branch lines in agricultural areas whose viability depended on the economics of grain transport. The Western Grain Transportation Act of 1983 addressed this case specifically, but

468-426: Is double-track from Norwich to Hoveton & Wroxham , where it becomes single-track with a passing loop at North Walsham , and two platforms at Cromer also allowing passing. The line is not electrified ; it has a loading gauge of W8 between Norwich and Roughton Road and W6 from Roughton Road to Sheringham. The maximum speed is 75 miles per hour (121 km/h). The line was re-signalled in 2000, leading to

507-556: Is a type of secondary track used by railroads to allow customers at a location to load and unload railcars without interfering with other railroad operations. Industrial spurs can vary greatly in length and railcar capacity depending on the requirements of the customer the spur is serving. In heavily industrialized areas, it is not uncommon for one industrial spur to have multiple sidings to several different customers. Typically, spurs are serviced by local trains responsible for collecting small numbers of railcars and delivering them to

546-421: Is allowed on the line at a time. On single-track lines with passing loops, measures must be taken to ensure that only one train in one direction can use a stretch of single track at a time, as head-on collisions are a particular risk. Some form of signalling system is required. In traditional British practice (and countries using British practice), single-track lines were operated using a token system where

585-497: Is part of Network Rail Strategic Route 7 , SRS 07.11, and is classified as a rural line. Passenger services are operated by Greater Anglia , which also manages all of the stations. The line was granted permission in 1864 and the first stretch was opened between Norwich and North Walsham in 1874 by the East Norfolk Railway . It was extended to Cromer by 1877 before being extended to Sheringham in 1877, using

624-532: The Bay of Plenty Region , lines were built inland to provide rail access to large logging operations. Today, many of the branch lines have been closed, including almost all of the general-purpose country lines. Those that remain serve ports or industries far from main lines such as coal mines, logging operations, large dairying factories, and steelworks . In Auckland and Wellington , two branch lines in each city exist solely for commuter passenger trains. For more, see

663-830: The Department for Transport in September 2007. The section of the line between Sheringham and Holt which was closed in the 1960s remains in use as a heritage railway line operated as the North Norfolk Railway (NNR - also known as the Poppy Line). After a period of 36 years, the link between the Bittern line and the North Norfolk Railway was reinstated in 2010 with the opening of a new level crossing at Sheringham. Sheringham railway station

702-753: The Gladstone Branch in New Jersey; as well as the New Canaan Branch , Danbury Branch , and Waterbury Branch in Connecticut . The Long Island Rail Road also refers to its services as "branches". In Chile, there are a lot of branch lines on its main line, of only a few remain operational. Most only operating in turistic services (like the Antilhue-Valdivia branch line), others have been taken over by other railways (like

741-788: The North South Line between Jurong East and Choa Chu Kang stations was operated as a separate line, known as the Branch line . It was merged into the North–South Line with the opening of the Woodlands Extension in 1996. The future Jurong Region Line and Cross Island Line will also have branch lines. New Zealand once had a very extensive network of branch lines, especially in the South Island regions of Canterbury , Otago , and Southland . Many were built in

780-612: The Pisa-Rome railway mainline at Roma San Pietro railway station , to Vatican City station . Many British railway branch lines were closed as a result of the " Beeching cuts " in the 1960s, although some have been re-opened as heritage railways . The smallest branch line that is still in operation in the UK is the Stourbridge Town Branch Line from Stourbridge Junction going to Stourbridge Town . Operating on

819-704: The South Tseung Kwan O Spur Line to LOHAS Park station , opened in 2009. Earlier, a spur line was built in 1985 on the East Rail line to serve Racecourse station , bypassing Fo Tan station . Also, the Tsim Sha Tsui Extension  [ yue ] was built in 2004 on the East Rail line to serve East Tsim Sha Tsui station . However, after the Kowloon Southern Link was completed in 2009, this spur line turns into

858-466: The list of New Zealand railway lines . Single-track railway Single track is significantly cheaper to build and maintain, but has operational and safety disadvantages. For example, a single-track line that takes 15 minutes to travel through would have capacity for only two trains per hour in each direction safely. By contrast, a double track with signal boxes four minutes apart can allow up to 15 trains per hour in each direction safely, provided all

897-695: The San Rosendo-Talcahuano branch line, which has been taken over by Biotrén and the Laja-Talcahuano train service) however, there is one branch line that still remains as fully operative. The Talca-Constitución branch line, which uses trains with bus motors. Two extensions to the MTR rapid transit network were built as branches of existing lines: the Lok Ma Chau Spur Line to Lok Ma Chau station , which opened in 2007; and

936-560: The U.S. state of New Jersey . The line is a short branch of the Northeast Corridor Line , running from Princeton Junction northwest to Princeton with no intermediate stops. Also known as the "Dinky Line", at 2.9 mi (4.7 km) it is the shortest scheduled commuter rail line in the United States. The run takes 4 minutes, 47 seconds. Other than the Princeton Line, other surviving branch lines include

975-600: The closure of a number of mechanical signal boxes and control moving to a panel at the Trowse Swing Bridge control room. This saw the end of one of the few remaining sections of single-track main line controlled by tokens. The Cromer signal box has been preserved. A new station is proposed as part of the Rackheath eco-town . The building of the town may also mean a short freight spur being built to transport fuel to fire an on-site power station. The plans for

1014-485: The early days of railways in North America it was common to rely upon simple timetable operation where operators knew where a train was scheduled to be at a particular time, and so would not enter a single-track stretch when they were not scheduled to. This generally worked but was inflexible and inefficient. It was improved with the invention of the telegraph and the ability to issue train orders . Converting

1053-569: The first president of the Canadian National Railway , said that although most branch lines cannot pay for themselves, they are even essential to make main lines pay. In the United States, abandonment of unproductive branch lines was a byproduct of deregulation of the rail industry through the Staggers Act . The Princeton Branch is a commuter rail line and service owned and operated by New Jersey Transit (NJT) in

1092-416: The greater flexibility and economic savings of trucking. Today, railroads remain the most economical way to ship large quantities of material, a fact that is reflected in industrial spurs. Most modern day spurs serve very large industries that require hundreds, if not thousands, of carloads a year. There is an international branch line between Italy and Vatican: the 300-metre Vatican Railway , connecting from

1131-546: The late 19th century to open up inland regions for farming and other economic activities. The branches in the South Island regions were often general-purpose lines that carried predominantly agricultural traffic, but lines elsewhere were often built to serve a specific resource: on the West Coast , an extensive network of branch lines was built in rugged terrain to serve coal mines, while in the central North Island and

1170-435: The lesser-used stations along the line, such as Salhouse , Gunton and Roughton Road . In 2019, new Class 755 bi-mode trains began to replace the previous mixture of Class 153 , Class 156 and Class 170 diesel multiple units . The line is also used by freight trains which are operated by GB Railfreight . Some trains carry gas condensate from a terminal at North Walsham to Harwich International Port . The line

1209-572: The railways had owned. However, by the mid-20th century, railways began neglecting lines in western agricultural regions. This was historically driven by factors such as the Crow Rate , which regulated the price railways could charge for shipping grain. Railways had little incentive to invest in rural Prairie branch lines, but were legally unable to abandon them under the National Transportation Act , which also did not provide

1248-425: The settlement received approval from the government in 2009. Branch line A branch line is a secondary railway line which branches off a more important through route, usually a main line . A very short branch line may be called a spur line . Branch lines may serve one or more industries, or a city or town not located on a main line. Branch lines may also connect two or more main lines. An industrial spur

1287-833: The short line often continuing to exist as a subsidiary. For example, when the Canadian Pacific acquired the Algoma Eastern Railway (a short line) in 1930, it soon after abandoned much of the Algoma Eastern mainline, but retained sections close to Algoma Eastern–Canadian Pacific junctions as short branch lines or spurs. The National Transportation Act of 1967 provided government subsidies for branch lines. Western railway development in Canada worked in concert with land settlement and cultivation, as pioneers were settled near railway lines, often on land

1326-594: The train driver had to be in possession of a token in order to enter a stretch of single track. Because there was only one unique token issued at any one time for each stretch of single track, it was impossible for more than one train to be on it at a time. This method is still used on some minor lines but in the longest single-track lines in Britain (e.g. the Highlands of Scotland) this has been superseded by radio communication, known as Radio Electronic Token Block . In

1365-424: The trains travel at the same speed. This hindrance on the capacity of a single track may be partly overcome by making the track one-way on alternate days. Long freight trains are a problem if the passing stretches are not long enough. Other disadvantages include the propagation of delays, since one delayed train on a single track will also delay any train waiting for it to pass. Also, a single track does not have

1404-467: The world. Industries of the era were commonly built along railroad lines specifically to allow for easy access to shipping. Short (under a mile, oftentimes only several hundred yards) industrial spurs with very small (under ten car) capacities were a common sight along railroads in industrial and rural cities alike. As automobile and roadway technology improved throughout the early and mid-20th century, most low volume industry spurs were abandoned in favor of

1443-504: Was further extended to Vaishali in 2011. The line is planned to be extended from Vaishali to Mohan Nagar via Sahibabad Station to link with the main line. The East West Line of the MRT system in Singapore has a two-station branch to Changi Airport . The first station, Expo , opened in 2001. It was extended to Changi Airport station the next year. From 1990 to 1996, the section of

1482-502: Was repealed in 1994 in the wake of the North American Free Trade Agreement and budget-balancing initiatives in favour of a one-time payout by the federal government directly to farmers, to arrange transport of grain themselves. From the mid-1970s to the late 2010s, more than 9,300 kilometres (5,800 mi) of Prairie branch lines were abandoned or had a discontinuance of service. David Blyth Hanna ,
