Tag Wiki 'Track Gauge'.

In , track gauge (in , alternatively track gage) is the distance between the two rails of a . All vehicles on a rail network must have wheelsets that are compatible with the track gauge. Since many different track gauges exist worldwide, gauge differences often present a barrier to wider operation on railway networks.

The term derives from the metal bar, or gauge, that is used to ensure the distance between the rails is correct.

Railways also deploy two other gauges to ensure compliance with a required standard. A is a two-dimensional profile that encompasses a cross-section of the track, a rail vehicle and a maximum-sized load: all rail vehicles and their loads must be contained in the corresponding envelope. A specifies the outline into which structures (bridges, platforms, lineside equipment etc.) must not encroach.

Uses of the term
The most common use of the term "track gauge" refers to the transverse distance between the inside surfaces of the two load-bearing rails of a , usually measured at to below the top of the rail head in order to clear worn corners and allow for rail heads having sloping sides. The term derives from the "gauge", a metal bar with a precisely positioned lug at each end that track crews use to ensure the actual distance between the rails lies within tolerances of a prescribed standard: on curves, for example, the spacing is wider than normal.

Deriving from the name of the bar, the distance between these rails is also referred to as the track gauge.

Selection of gauge

Early track gauges
The earliest form of railway was a wooden wagonway, along which single wagons were manhandled, almost always in or from a mine or quarry. Initially the wagons were guided by human muscle power; subsequently by various mechanical methods. Timber rails wore rapidly: later, flat cast-iron plates were provided to limit the wear. In some localities, the plates were made L-shaped, with the vertical part of the L guiding the wheels; this is generally referred to as a "plateway". Flanged wheels eventually became universal, and the spacing between the rails had to be compatible with that of the wagon wheels.M. J. T. Lewis (1970), Early Wooden Railways, Routledge Keegan Paul, London

As the guidance of the wagons was improved, short strings of wagons could be connected and pulled by teams of horses, and the track could be extended from the immediate vicinity of the mine or quarry, typically to a navigable waterway. The wagons were built to a consistent pattern and the track would be made to suit the needs of the horses and wagons: the gauge was more critical. The of 1802 in South Wales, a plateway, spaced these at over the outside of the upstands.R. Cragg (1997), Civil Engineering Heritage – Wales and West Central, Thomas Telford Publishing, London, 2nd edition, England,

Penydarren Tramroad probably carried the first journey by a locomotive, in 1804, and it was successful for the locomotive, but unsuccessful for the track: the plates were not strong enough to carry its weight. A considerable progressive step was made when cast iron edge rails were first employed; these had the major axis of the rail section configured vertically, giving a much stronger section to resist bending forces, and this was further improved when fish-belly rails were introduced.Andy Guy and Jim Rees, Early Railways 1569–1830, Shire Publications in association with the National Railway Museum, Oxford, 2011,

Edge rails required a close match between rail spacing and the configuration of the wheelsets, and the importance of the gauge was reinforced. Railways were still seen as local concerns: there was no appreciation of a future connection to other lines, and selection of the track gauge was still a pragmatic decision based on local requirements and prejudices, and probably determined by existing local designs of (road) vehicles.

Standard gauge appears
were being developed in the first decades of the 19th century; they took various forms, but George Stephenson developed a successful locomotive on the Wagonway, where he worked. His designs were so successful that they became the standard, and when the Stockton and Darlington Railway was opened in 1825, it used his locomotives, with the same gauge as the Killingworth line, .W W Tomlinson, The North Eastern Railway, its Rise and Development, Andrew Reid & Co, Newcastle upon Tyne, 1915Nicholas Wood, A Practical Treatise on Rail-Roads, Longman, Orme, Brown, Green and Longmans, London, Third edition, 1838

The Stockton and Darlington line was immensely successful, and when the Liverpool and Manchester Railway, the first intercity line, was built (it opened in 1830), it used the same gauge. It was also hugely successful, and the gauge (now eased to ), became the automatic choice: "".

Gauge differences
The Liverpool and Manchester was quickly followed by other trunk railways, with the Grand Junction Railway and the London and Birmingham Railway forming a huge critical mass of . When Bristol promoters planned a line from London, they employed the innovative engineer Isambard Kingdom Brunel. He decided on a wider gauge, to give greater stability, and the Great Western Railway adopted a gauge of , later eased to . This became known as . The Great Western Railway (GWR) was successful and was greatly expanded, directly and through friendly associated companies, widening the scope of broad gauge.

At the same time, other parts of Britain built railways to standard gauge, and British technology was exported to European countries and parts of North America, also using standard gauge. Britain polarised into two areas: those that used and those that used standard gauge. In this context, standard gauge was referred to as "narrow gauge" to indicate the contrast. Some smaller concerns selected other non-standard gauges: the Eastern Counties Railway adopted . Most of them converted to standard gauge at an early date, but the GWR's broad gauge continued to grow.

The larger railway companies wished to expand geographically, and large areas were considered to be under their control. When a new independent line was proposed to open up an unconnected area, the gauge was crucial in determining the allegiance that the line would adopt: if it was broad gauge, it must be friendly to the Great Western railway; if narrow (standard) gauge, it must favour the other companies. The battle to persuade or coerce that choice became very intense, and became referred to as .

As passenger and freight transport between the two areas became increasingly important, the difficulty of moving from one gauge to the other—the —became more prominent and more objectionable. In 1845 a Royal Commission on Railway Gauges was created to look into the growing problem, and this led to the Regulating the Gauge of Railways Act 1846, which forbade the construction of broad gauge lines unconnected with the broad gauge network. The broad gauge network was eventually converted—a progressive process completed in 1892, called gauge conversion. The same Act mandated the gauge of for use in Ireland.

Gauge selection in other countries
, from left: , , and , on display at the China Railway Museum in ]] As railways were built in other countries, the gauge selection was pragmatic: the track would have to fit the rolling stock. If locomotives were imported from elsewhere, especially in the early days, the track would be built to fit them. In some cases standard gauge was adopted, but many countries or companies chose a different gauge as their national gauge, either by governmental policy, or as a matter of individual choice. The Russian Railways and Imperial Intersections in the Russian Empire, Karl E. M. Starns, Thesis, University of Washington 2012, p. 33

Standard gauge is generally known world-wide as being . Terms such as broad gauge and narrow gauge do not have any fixed meaning beyond being materially wider or narrower than standard.

In British practice, the space between the rails of a track is colloquially referred to as the "four-foot", and the space between two tracks the "six-foot", descriptions relating to the respective dimensions.

Standard gauge
In modern usage the term "standard gauge" refers to . Standard gauge is dominant in a majority of countries, including those in North America, most of western Europe, North Africa and the Middle east, and in China.

Broad gauge
In modern usage, the term "broad gauge" generally refers to track spaced significantly wider than .

Broad gauge is the dominant gauge in countries in Indian subcontinent, the former Soviet Union (CIS states, Baltic states, Georgia and Ukraine), Mongolia and Finland, Spain, Portugal, Argentina, Chile and Ireland. It is also use for the suburban railway systems in South Australia, and Victoria, .

Medium gauge
The term "medium gauge" had different meanings throughout history, depending on the local dominant gauge in use.

In 1840s, the was considered a medium gauge compared to Brunel's and the narrow gauge, nowadays being .

Narrow gauge
In modern usage, the term "narrow gauge" generally refers to track spaced significantly narrower than .

Narrow gauge is the dominant or second dominant gauge in countries of Southern, Central Africa, East Africa, Southeast Asia, Japan, Taiwan, Philippines, Central America and South America,

During the period known as "the Battle of the gauges", Stephenson's standard gauge was commonly known as "narrow gauge", while Brunel's railway's gauge was termed "". Many narrow gauge railways were built in mountainous regions such as , the of North America, Central Europe and South America. Industrial railways and across the world are often narrow gauge. Sugar cane and banana plantations are mostly served by narrow gauges.

Very narrow gauges of under were used for some industrial railways in space-restricted environments such as or farms. The French company developed and tracks, mainly for mines; Heywood developed gauge for estate railways. The most common minimum-gauges were ,

Break of gauge
operation between railway networks with different gauges was originally impossible; goods had to be transshipped and passengers had to change trains. This was obviously a major obstacle to convenient transport, and in Great Britain, led to political intervention.

On narrow gauge lines, or transporter wagons are used: standard gauge wagons are carried on narrow gauge lines on these special vehicles, generally with rails of the wider gauge to enable those vehicles to roll on and off at transfer points.

On the Transmongolian Railway, Russia and Mongolia use while China uses the standard gauge of 1,435 mm. At the border, each carriage is lifted and its . The operation can take several hours for a whole train of many carriages.

Other examples include crossings into or out of the former Soviet Union: Ukraine/Slovakia border on the Bratislava–L'viv train, and the Romania/Moldova border on the Chișinău-Bucharest train.

A system developed by and Construcciones y Auxiliar de Ferrocarriles (CAF) of Spain uses variable gauge wheelsets; at the border between France and Spain, through passenger trains are drawn slowly through apparatus that alters the gauge of the wheels, which slide laterally on the axles.Alberto García Álvarez, Automatic Gauge Changeover for Trains in Spain, Fundación de los Ferrocarrilos Españoles, 2010, online at [2]

A similar system is used between China and Central Asia, and between Poland and Ukraine, using the SUW 2000 and variable axle systems.Experience and results of operation the SUW 2000 system in traffic corridors at China and Poland use standard gauge, while Central Asia and Ukraine use .

Dual gauge
When individual railway companies have chosen different gauges and have needed to share a route where space on the ground is limited, (or dual gauge) track, in which three (sometimes four) rails are supported in the same track structure, can be necessary. The most frequent need for such track was at the approaches to city terminals or at break-of-gauge stations.

Tracks of multiple gauges involve considerable costs in construction (including signalling work) and complexities in track maintenance, and may require some speed restrictions. They are therefore built only when absolutely necessary. If the difference between the two gauges is large enough – for example between and – three-rail dual-gauge is possible, but if not – for example between and – four rails must be used. Dual-gauge rail lines occur (or have occurred) in Argentina, Australia, Brazil, Japan, North Korea, Spain, Switzerland, Tunisia and Vietnam.

On the GWR, there was an extended period between political intervention in 1846 that prevented major expansion of its The Act of Parliament did not prohibit expansion of the existing broad gauge system, but it had the indirect and delayed effect of forcing conformity with the "standard" gauge eventually. and the final gauge conversion to standard gauge in 1892. During this period, many locations practicality required mixed gauge operation, and in station areas the track configuration was extremely complex. This was compounded by the common rail having to be at the platform side in stations; therefore, in many cases, standard-gauge trains needed to be switched from one side of the track to the other at the approach. A special fixed point arrangement was devised for the purpose, where the track layout was simple enough.S.C. Jenkins and R.C. Langley, The West Cornwall Railway, The Oakwood Press, Usk, 2002, ISBN 0853615896, gives an illustration and description on page 66.

In some cases, mixed gauge trains were operated with wagons of both gauges. For example, MacDermotE T MacDermot, History of the Great Western Railway, vol II: 1863–1921, published by the Great Western Railway, London, 1931, p. 316 wrote:

In November 1871 a novelty in the shape of a mixed-gauge goods train was introduced between Truro and Penzance. It was worked by a narrow-gauge engine, and behind the narrow-gauge trucks came a broad-gauge match-truck with wide buffers and sliding shackles, followed by the broad-gauge trucks. Such trains continued to run in West Cornwall until the abolition of the Broad Gauge; they had to stop or come down to walking pace at all stations where fixed points existed and the narrow portion side-stepped to right or left.

Nominal track gauge
The nominal track gauge is the distance between the inner faces of the rails. In current practice, it is specified at a certain distance below the rail head as the inner faces of the rail head (the gauge faces) are not necessarily vertical. Some amount of tolerance is necessarily allowed from the nominal gauge to allow for wear, etc.; this tolerance is typically greater for track limited to slower speeds, and tighter for track where higher speeds are expected (as an example, in the US the gauge is allowed to vary between to for track limited to , while track is allowed only to . Given the allowed tolerance, it is a common practice to widen the gauge slightly in curves, particularly those of shorter radius (which are inherently slower speed curves).

Rolling stock on the network must have running gear (wheelsets) that are compatible with the gauge, and therefore the gauge is a key parameter in determining interoperability, but there are many others – see below. In some cases in the earliest days of railways, the railway company saw itself as an infrastructure provider only, and independent hauliers provided wagons suited to the gauge. Colloquially the wagons might be referred to as "four-foot gauge wagons", say, if the track had a gauge of four feet. This nominal value does not equate to the flange spacing, as some freedom is allowed for.

An infrastructure manager might specify new or replacement track components at a slight variation from the nominal gauge for pragmatic reasons.

The gauge is defined in , or SI units.

Imperial units were established in the United Kingdom by The Weights and Measures Act of 1824. The United States customary units for length did not agree with the Imperial system until 1959, when one international yard was defined as 0.9144 meters and, as derived units, 1 foot (= yd) as 0.3048 meter and 1 inch (= yd) as 25.4 mm.

The list shows the Imperial and other units that have been used for track gauge definitions:

Temporary way – permanent way
A temporary way is the temporary track often used for construction, to be replaced by the (the structure consisting of the rails, fasteners, and (or slab track), plus the underlying subgrade) when construction nears completion. In many cases narrow-gauge track is used for a temporary way because of the convenience in laying it and changing its location over unimproved ground.

In restricted spaces such as tunnels, the temporary way might be double track even though the tunnel will ultimately be single track. The Airport Rail Link in Sydney had construction trains of gauge, which were replaced by permanent tracks of gauge.

During World War I trench warfare led to a relatively static disposition of infantry, requiring considerable logistics to bring them support staff and supplies (food, ammunition, earthworks materials, etc.). Dense light railway networks using temporary narrow gauge track sections were established by both sides for this purpose.Christian Wolmar, Engines of War: How Wars Were Won & Lost on the Railways, Atlantic Books, London, 2010,

In 1939 it was proposed to construct the western section of the Yunnan–Burma Railway using a gauge of , since such tiny or "toy" gauge facilitates the tightest of curves in difficult terrain.

Maintenance standards
Infrastructure owners specify permitted variances from the nominal gauge, and the required interventions when non-compliant gauge is detected. For example, the Federal Railroad Administration in the USA specifies that the actual gauge of a 1,435 mm track that is rated for a maximum of must be between and .

Advantages and disadvantages of different track gauges
Speed, capacity, and economy are generally objectives of rail transport, but there is often an inverse relationship between these priorities. There is a common misconception that a narrower gauge permits a tighter turning radius, but for practical purposes, there is no meaningful relationship between gauge and curvature.

Construction cost
Narrower gauge railways usually cost less to build because they are usually lighter in construction, using smaller and (smaller ), as well as smaller , smaller (smaller ). Narrow gauge is thus often used in mountainous terrain, where the savings in civil engineering work can be substantial. It is also used in sparsely populated areas, with low potential demand, and for temporary railways that will be removed after short-term use, such as for construction, the logging industry, the mining industry, or large-scale construction projects, especially in confined spaces (see Temporary way – permanent way). For temporary railways which will be removed after short-term use, such as those used in logging, mining or large-scale construction projects (especially in confined spaces, such as when constructing the ), a narrow-gauge railway is substantially cheaper and easier to install and remove. Such railways have almost vanished, however, due to the capabilities of modern . In many countries, narrow-gauge railways were built as branch lines to feed traffic to standard-gauge lines due to lower construction costs. The choice was often not between a narrow- and standard-gauge railway, but between a narrow-gauge railway and none at all.

Broader gauge railways are generally more expensive to build, because they are usually heavier in construction, use larger and (larger ), as well as larger , larger (larger ). But broader gauges offer higher speed and capacity. For routes with high traffic, greater capacity may more than offset the higher initial cost of construction.

The value or a user derives from a or service depends on the number of users of compatible products – the "" in economics. Network effects are typically positive, resulting in a given user deriving more value from a product as other users join the same network.

At national levels, the network effect has resulted in commerce extending beyond regional and national boundaries. Increasingly, many governments and companies have made their railways' engineering and operational standards compatible in order to achieve interchangeability – hence faster, longer-distance train operation. A major barrier to achieving interchangeability, however, is
(2022). 9781858989846
– in this context the persistence of an already adopted standard to which equipment, infrastructure and training has become aligned. Since adopting a new standard is difficult and expensive, continuing with an existing standard can remain attractive unless longer-term benefits are given appropriate weight. An example of the consequences of path dependence is the persistence in the – the earliest nation to develop and adopt railway technologies – of that are too small to allow the larger of continental Europe to operate in that country. The reduced cost, greater efficiency, and greater economic opportunity offered by the use of a common standard has resulted in the historical multitude of track gauges dwindling to a small number that predominate worldwide.

When interchangeability has not been achieved, freight and passengers must be transferred through time-consuming procedures requiring manual labour and substantial capital expenditure. Some bulk commodities, such as , , and , can be mechanically , but even this is time-consuming, and the equipment required for the transfer is often complex to maintain. Further, if rail lines of different gauges coexist in a network and a break of gauge exists, it is difficult in times of peak demand to move rolling stock to where it is needed. Sufficient rolling stock must be available to meet a narrow-gauge railway's peak demand (which might be greater in comparison to a broader-gauge network), and the surplus equipment generates no cash flow during periods of low demand. In regions where narrow-gauge lines form a small part of the rail network (as was the case on Russia's ), extra cost is involved in designing, manufacturing or importing narrow-gauge equipment.

Solutions to interchangeability problems include , a system, , , or .

Further convergence of rail gauge use seems likely, as countries seek to build inter-operable networks, and international organisations seek to build macro-regional and continental networks. Almost all new lines are built to standard gauge, except in Uzbekistan and Russia.

EU funds have been dedicated to assist , , and in the building of some key railway lines () of , and to assist Spain and Portugal in the construction of high-speed lines to connect Iberian cities to one another and to the French high-speed lines. The EU has developed plans for improved freight rail links between Spain, Portugal, and the rest of Europe.

Trans-Asian Railway
The Economic and Social Commission for Asia and the Pacific (UNESCAP) is planning a Trans-Asian Railway that will link Europe and the Pacific, with a Northern Corridor from Europe to the Korean Peninsula, a Southern Corridor from Europe to Southeast Asia, and a North–South corridor from Northern Europe to the Persian Gulf. All these would encounter breaks of gauge as they cross Asia. Current plans have mechanized facilities at the breaks of gauge to move containers from train to train rather than widespread gauge conversion. The Northern Corridor through Russia already operates since before year 2000, with increasing volumes China–Europe.
