Track gauge conversion
Gauge conversion is the changing of one railway track gauge (the distance between the running rails) to another. If tracks are converted to a narrower gauge, the existing sleepers (ties) may be used. However, replacement is required if the conversion is to a wider gauge. Some sleepers may be long enough to accommodate the fittings of both existing and alternative gauges. Wooden sleepers are suitable for conversion because they can be drilled for the repositioned rail spikes.
Groove (engineering)
In manufacturing or mechanical engineering a groove is a long and narrow indentation built into a material, generally for the purpose of allowing another material or part to move within the groove and be guided by it. Examples include: A canal cut in a hard material, usually metal. This canal can be round, oval or an arc in order to receive another component such as a boss, a tongue or a gasket. It can also be on the circumference of a dowel, a bolt, an axle or on the outside or inside of a tube or pipe etc.
Birmingham New Street railway station
Birmingham New Street, also known as New Street station, is the largest and busiest of the three main railway stations in Birmingham city centre, England, and a central hub of the British railway system. It is a major destination for Avanti West Coast services from , , and via the West Coast Main Line, the CrossCountry network, and for local and suburban services within the West Midlands; this includes those on the Cross-City Line between , and , and the Chase Line to and . The three-letter station code is BHM.
Track geometry
Track geometry is concerned with the properties and relations of points, lines, curves, and surfaces in the three-dimensional positioning of railroad track. The term is also applied to measurements used in design, construction and maintenance of track. Track geometry involves standards, speed limits and other regulations in the areas of track gauge, alignment, elevation, curvature and track surface. Standards are usually separately expressed for horizontal and vertical layouts although track geometry is three-dimensional.
Engineering tolerance
Engineering tolerance is the permissible limit or limits of variation in: a physical dimension; a measured value or physical property of a material, manufactured object, system, or service; other measured values (such as temperature, humidity, etc.); in engineering and safety, a physical distance or space (tolerance), as in a truck (lorry), train or boat under a bridge as well as a train in a tunnel (see structure gauge and loading gauge); in mechanical engineering, the space between a bolt and a nut or a hole, etc.
Ballastless track
A ballastless track or slab track is a type of railway track infrastructure in which the traditional elastic combination of ties/sleepers and ballast is replaced by a rigid construction of concrete or asphalt. In ballastless tracks, the rails are rigidly fastened to special types of concrete ties/sleepers that are themselves set in concrete. Ballastless tracks therefore offer a high consistency in track geometry, the adjusting of which is not possible after the concreting of the superstructure.
Road–rail vehicle
A road–rail vehicle or a rail–road vehicle is a dual-mode vehicle which can operate both on rail tracks and roads. They are also known as two-way vehicles (Zweiwegefahrzeug), hi-rail (from highway and railway, or variations such as high-rail, HiRail, Hy-rail), and rail and road vehicles. They are often converted road vehicles, keeping their normal wheels with rubber tires, but fitted with additional flanged steel wheels for running on rails.
Conservation and restoration of rail vehicles
Conservation and restoration of rail vehicles aims to preserve historic rail vehicles. It may concern trains that have been removed from service and later restored to their past condition, or have never been removed from service, like UP 844, the only U.S. steam locomotive to never be retired. They are often operated in present-day service as moving examples of living history, as opposed to static exhibits.
Network length (transport)
In transport terminology, network length (or, less often, system length) refers to the total length of a transport network, and commonly also refers to the length of any fixed infrastructure associated with the network. A measurement can be made of the network length of various different modes of transport, including rail, bus, road and air. The measurement may focus on one of a number of specific characteristics, such as route length, line length or track length.
Conductor (rail)
A conductor (North American English) or guard (Commonwealth English) is a train crew member responsible for operational and safety duties that do not involve actual operation of the train/locomotive. The conductor title is most common in North American railway operations, but the role is common worldwide under various job titles. In Commonwealth English, a conductor is also known as guard or train manager.
