A railway track or railroad track, also known as a train track or permanent way, is the structure on a railway or railroad consisting of the rails, fasteners, railroad ties and ballast, plus the underlying subgrade. It enables trains to move by providing a dependable surface for their wheels to roll upon. Early tracks were constructed with wooden or cast iron rails, and wooden or stone sleepers; since the 1870s, rails have almost universally been made from steel.
A third rail, also known as a live rail, electric rail or conductor rail, is a method of providing electric power to a railway locomotive or train, through a semi-continuous rigid conductor placed alongside or between the rails of a railway track. It is used typically in a mass transit or rapid transit system, which has alignments in its own corridors, fully or almost fully segregated from the outside environment. Third-rail systems are usually supplied from direct current electricity.
William Henry Barlow was an English civil engineer of the 19th century, particularly associated with railway engineering projects. Barlow was involved in many engineering enterprises. He was engineer for the Midland Railway on its London extension and designed the company's London terminus at St Pancras.
The railway track or permanent way is the elements of railway lines: generally the pairs of rails typically laid on the sleepers or ties embedded in ballast, intended to carry the ordinary trains of a railway. It is described as a permanent way because, in the earlier days of railway construction, contractors often laid a temporary track to transport spoil and materials about the site; when this work was substantially completed, the temporary track was taken up and the permanent way installed.
A railroad tie, crosstie, railway tie or railway sleeper is a rectangular support for the rails in railroad tracks. Usually laid perpendicular to the rails, ties transfer loads to the track ballast and subgrade, hold the rails upright and keep them spaced to the correct gauge.
Stressing is a rail engineering process. It is used to prevent heat and cold tension after installation of continuous welded rail (CWR). Environmental heat causes CWR to expand and therefore can cause the fixed track to buckle. Environmental cold can lead to the contraction of the fixed railway track causing brittleness and cracks. Before it is installed, the rail is altered by stretching with hydraulic tensors or heated to its stress-free temperature to make these dangerous problems less likely.
The Lynton and Lynmouth Cliff Railway is a water-powered funicular joining the twin towns of Lynton and Lynmouth on the rugged coast of North Devon in southwest England.
Pandrol is a global railway infrastructure equipment and technology company. It is presently a member of the Delachaux Group and based in Colombes, France and has 1,700 employees globally in over 40 locations. Pandrol has sold its various products to over 400 railway systems around the world.
Tramway track is used on tramways or light rail operations. As with standard rail tracks, tram tracks have two parallel steel rails, the distance between the heads of the rails being the track gauge. When there is no need for pedestrians or road vehicles to traverse the track, conventional flat-bottom rail is used. However, when such traffic exists, such as in urban streets, grooved rails are used.
Railway engineering is a multi-faceted engineering discipline dealing with the design, construction and operation of all types of rail transport systems. It encompasses a wide range of engineering disciplines, including civil engineering, computer engineering, electrical engineering, mechanical engineering, industrial engineering and production engineering. A great many other engineering sub-disciplines are also called upon.
The rail profile is the cross sectional shape of a railway rail, perpendicular to its length.
Exothermic welding, also known as exothermic bonding, thermite welding (TW), and thermit welding, is a welding process that employs molten metal to permanently join the conductors. The process employs an exothermic reaction of a thermite composition to heat the metal, and requires no external source of heat or current. The chemical reaction that produces the heat is an aluminothermic reaction between aluminium powder and a metal oxide.
A concrete sleeper or concrete tie is a type of railway sleeper or railroad tie made out of steel reinforced concrete.
A rail fastening system is a means of fixing rails to railroad ties or sleepers. The terms rail anchors, tie plates, chairs and track fasteners are used to refer to parts or all of a rail fastening system. The components of a rail fastening system may also be known collectively as other track material, or OTM for short. Various types of fastening have been used over the years.
Ladder track is a type of railway track in which the track is laid on longitudinal supports with transverse connectors holding the two rails at the correct gauge distance. Modern ladder track can be considered a development of baulk road, which supported rails on longitudinal wooden sleepers. Synonyms include longitudinal beam track.
The Engineering Heritage Awards, formally known as the Engineering Heritage Hallmark Scheme, were established by the Institution of Mechanical Engineers (IMechE) in 1984 to identify and promote artefacts, locations, collections and landmarks of significant engineering importance.
A stoneblower is a railway track maintenance machine that automatically lifts and packs the sleepers with small grade ballast, which is blown under the sleepers to level the track. An alternative to the use of a ballast tamper, the totally self-contained machine levels track without the use of a large gang of workmen.
The Park series or Park car is a fleet of lightweight streamlined dome-sleeper-observation cars built by the Budd Company for the Canadian Pacific Railway in 1954. Sixteen of the cars were named for a Canadian national or provincial park, while one was named for a wildlife reserve, and one was named for what was at the time a private park owned by Canadian Pacific subsidiary Dominion Atlantic Railway, but is now one of the National Historic Sites of Canada. Via Rail acquired the fleet from Canadian Pacific in 1978 and the majority of the cars remain in active service.
The Çorlu train derailment was a fatal railway accident which occurred in 2018 at the Çorlu district of Tekirdağ Province in northwestern Turkey when a train derailed, killing 24 passengers and injuring 318, including 42 severely.
