A broad-gauge railway is a railway with a track gauge broader than the 1,435 mm used by standard-gauge railways.
VR-Group Plc, commonly known as VR, is a government-owned railway company in Finland. VR's most important function is the operation of Finland's passenger rail services with 250 long-distance and 800 commuter rail services every day. With 7,500 employees and net sales of €1,251 million in 2017, VR is one of the most significant operators in the Finnish public transport market area.
In rail transport, track gauge is the distance between the two rails of a railway track. 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.
A loading gauge is a diagram or physical structure that defines the maximum height and width dimensions in railway vehicles and their loads. Their purpose is to ensure that rail vehicles can pass safely through tunnels and under bridges, and keep clear of platforms, trackside buildings and structures. Classification systems vary between different countries, and gauges may vary across a network, even if the track gauge is uniform.
In railway engineering, "gauge" is the transverse distance between the inner surfaces of the heads of two rails, which for the vast majority of railway lines is the number of rails in place. However, it is sometimes necessary for track to carry railway vehicles with wheels matched to two different gauges. Such track is described as dual gauge – achieved either by addition of a third rail, if it will fit, or by two additional rails. Dual-gauge tracks are more expensive to configure with signals and sidings, and to maintain, than two separate single-gauge tracks. It is therefore usual to build dual-gauge or other multi-gauge tracks only when necessitated by lack of space or when tracks of two different gauges meet in marshalling yards or passenger stations. Dual-gauge tracks are by far the most common configuration, but triple-gauge tracks have been built in some situations.
Rail transport in the Australian state of Victoria is provided by a number of railway operators who operate over the government-owned railway lines. The network consists of 2,357 km of Victorian broad gauge lines, and 1,912 km of standard gauge freight and interstate lines; the latter increasing with gauge conversion of the former. Historically, a few experimental 762 mm gauge lines were built, along with various private logging, mining and industrial railways. The rail network radiates from the state capital, Melbourne, with main interstate links to Sydney and to Adelaide, as well as major lines running to regional centres, upgraded as part of the Regional Fast Rail project.
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.
Terra Transport (TT) was the name for the Newfoundland Transportation Division, a wholly owned subsidiary of Canadian National Railway (CN), created in 1979 as a means to organize the company's operations on Newfoundland.
With railways, a break of gauge occurs where a line of one track gauge meets a line of a different gauge. Trains and rolling stock generally cannot run through without some form of conversion between gauges, leading to passengers having to change trains and freight requiring transloading or transshipping; this can add delays, costs, and inconvenience to travel on such a route.
The Victorian Railways (VR), trading from 1974 as VicRail, was the state-owned operator of most rail transport in the Australian state of Victoria from 1859 to 1983. The first railways in Victoria were private companies, but when these companies failed or defaulted, the Victorian Railways was established to take over their operations. Most of the lines operated by the Victorian Railways were of 5 ft 3 in. However, the railways also operated up to five 2 ft 6 in narrow gauge lines between 1898 and 1962, and a 4 ft 8+1⁄2 instandard gauge line between Albury and Melbourne from 1961.
The Port of Turku is a port located in the south-west of Finland, where the mainland meets the beginning of the Turku archipelago. Sited within Finland's sixth largest city, the port principally handles traffic between Turku and the Swedish capital of Stockholm and the enclaved Åland.
The Finnish railway network consists of a total track length of 9,216 km (5,727 mi). The railways are built with a broad 1,524 mm track gauge, of which 3,249 km (2,019 mi) is electrified. Passenger trains are operated by the state-owned enterprise VR that runs services on 7,225 km (4,489 mi) of track. These services cover all major cities and many rural areas, though the coverage is less than the coverage provided by the bus services. Most passenger train services originate or terminate at Helsinki Central railway station, and a large proportion of the passenger rail network radiates out of Helsinki. VR also operates freight services. Maintenance and construction of the railway network itself is the responsibility of the Finnish Rail Administration, which is a part of the Finnish Transport Agency. The network consists of six areal centres, that manage the use and maintenance of the routes in co-operation. Cargo yards and large stations may have their own signalling systems.
Rail transport in Sweden uses a network of 15,006.25 km of track, the 22nd largest in the world. Construction of the first railway line in Sweden began in 1855. The major operator of passenger trains has traditionally been the state-owned SJ AB, though today around 70% of all rail traffic consists of subsidised local and regional trains for which the regional public transport authorities bear responsibility. Passenger traffic has increased significantly since the turn of the millennium, and in 2019 Sweden ranked number five in the world and number three in the European union, as well as number sixth in the world when measured by passenger share.
The Islamic Republic of Iran Railways is the national state-owned railway system of Iran. The Raja Passenger Train Company is an associate of the IR, and manages its passenger trains. The Railway Transportation Company is an associate of the IR, which manages its freight transport. The Ministry of Roads & Urban Development is the state agency that oversees the IRIR. Some 33 million tonnes of goods and 29 million passengers are transported annually by the rail transportation network, accounting for 9 percent and 11 percent of all transportation in Iran, respectively (2011).
A variable gauge system allows railway vehicles in a train to travel across a break of gauge between two railway networks with different track gauges.
The rail network in Queensland, Australia, was the first in the world to adopt 1,067 mm narrow gauge for a main line, and now the second largest narrow gauge network in the world, consists of:
In railroad industry, the Ramsey car-transfer apparatus was a device to replace bogies on railroad cars to permit transfer of a train between railroad lines with different gauge.
Bogie exchange is a system for operating railway wagons on two or more gauges to overcome difference in the track gauge. To perform a bogie exchange, a car is converted from one gauge to another by removing the bogies or trucks, and installing a new bogie with differently spaced wheels. It is generally limited to wagons and carriages, though the bogies on diesel locomotives can be exchanged if enough time is available.
Toronto-gauge railways are tram and rapid transit lines built to Toronto gauge, a broad gauge of 4 ft 10+7⁄8 in. This is 2+3⁄8 in (60 mm) wider than standard gauge of 4 ft 8+1⁄2 in which is by far the most common track gauge in Canada. The gauge is unique to the Greater Toronto Area and is currently used on the Toronto streetcar system and the Toronto subway, both operated by the Toronto Transit Commission. As well, the Halton County Radial Railway, a transport museum, uses the Toronto gauge so its rail line can accommodate its collection of Toronto streetcars and subway trains. Several now-defunct interurban rail systems also once used this gauge.
