A railroad car, railcar, railway wagon, railway carriage, railway truck, railwagon, railcarriage or railtruck, also called a train car, train wagon, train carriage or train truck, is a vehicle used for the carrying of cargo or passengers on a rail transport system. Such cars, when coupled together and hauled by one or more locomotives, form a train. Alternatively, some passenger cars are self-propelled in which case they may be either single railcars or make up multiple units.
Piggyback transportation refers to the transportation of goods where one transportation unit is carried on the back of something else. It is a specialised form of intermodal transportation and combined transport.
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.
The Leek and Manifold Valley Light Railway (L&MVLR) was a narrow gauge railway in Staffordshire, England that operated between 1904 and 1934. The line mainly carried milk from dairies in the region, acting as a feeder to the 4 ft 8+1⁄2 instandard gauge system. It also provided passenger services to the small villages and beauty spots along its route. The line was built to a 2 ft 6 in narrow gauge and to the light rail standards provided by the Light Railways Act 1896 to reduce construction costs.
A dual gauge railway line has track consisting of two rails spaced according to one track gauge, to which are added either one or two more rails spaced according to another track gauge. Since tracks of two gauges are more expensive to configure with signals and sidings, and to maintain, than two separate single-gauge tracks, it is usual to build dual-gauge tracks only when necessitated by lack of space.
Rail transport in Victoria, Australia, 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.
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.
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:
Rollbocks, sometimes called transporter trailers, are narrow gauge railway trucks or bogies that allow a standard gauge wagon to 'piggyback' on a narrow-gauge line. The Vevey system enables a coupled train of standard gauge wagons to be automatically loaded or rolled onto Rollbocks, so that the train can then continue through a change of gauge.
The former Victorian Railways, the state railway authority in Victoria, Australia, built a number of experimental 2 ft 6 in narrow-gauge lines around the beginning of the 20th century. Although all were closed by the early 1960s, parts of two have been reopened as heritage railways.
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.
Sparrowlee was the name of a railway station on the Leek and Manifold Valley Light Railway, a 2 ft 6 in narrow gauge line which ran for 8 miles between Hulme End and Waterhouses, in Staffordshire, and was initially operated by the North Staffordshire Railway before being taken over by the LMS.
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.
A well car, also known as a double-stack car, is a type of railroad car specially designed to carry intermodal containers used in intermodal freight transport. The "well" is a depressed section which sits close to the rails between the wheel trucks of the car, allowing a container to be carried lower than on a traditional flatcar. This makes it possible to carry a stack of two containers per unit on railway lines wherever the structure gauge assures sufficient clearance. The top container is secured to the bottom container either by a bulkhead built into the car, or through the use of inter-box connectors (IBC). Four IBCs are needed per wellcar. In the process of an inbound train becoming an outbound train, there are four processes: unlock to unload the top container of inbound train, remove then unload bottom container, insert after loading bottom container of outbound train, lock after top container loaded.
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.
5 ft 6 in / 1,676 mm, a broad gauge, is the track gauge used in India, Pakistan, western Bangladesh, Sri Lanka, Argentina, Chile, and on BART in San Francisco, United States.
The vast majority of North American railroads are standard gauge. Exceptions include some streetcar, subway and rapid transit systems, mining and tunneling operations, and some narrow-gauge lines particularly in the west, e.g. the isolated White Pass and Yukon Route system, and the former Newfoundland Railway.
Waterhouses railway station was a railway station that served the village of Waterhouses, Staffordshire. It was opened jointly by the North Staffordshire Railway (NSR) and the Leek and Manifold Valley Light Railway (L&MVLR) in 1905 and closed in 1943.
