Interactive 3D view. Dual-gauge track can consist of three rails, sharing one "common" rail; or four rails, with the rails of the narrower gauge lying between those of the broader gauge. In the three-rail configuration, wear and tear of the common rail is greater than with the two other outer rails.
The Wester Pipe Railway is a narrow gauge railway that runs from Hastigrow on the B876 road to Westerloch on the A99, all within Caithness. [1] The line is double track for most of the route and uses Metre gauge. It is used to transport pipeline segments to the sea. It is the second northernmost railway in the United Kingdom with the first ...
Scharfenberg coupler on a Southeastern Class 395. Video of ICE T coupling at Leipzig Hauptbahnhof. A coupling or coupler is a mechanism, typically located at each end of a rail vehicle, that connects them together to form a train. The equipment that connects the couplers to the vehicles is the draft gear or draw gear, which must absorb the ...
At the border with Sweden where the Torne separates the cities of Tornio, Finland and Haparanda, Sweden, a two-kilometre section of dual gauge track uses a gauntlet configuration because the 1,524 mm (5 ft) gauge used in Finland and 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge used in Sweden are too close for a common rail to be shared.
If the difference between the two gauges is large enough – for example between 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge and 3 ft 6 in (1,067 mm) – three-rail dual-gauge is possible, but if not – for example between 3 ft 6 in (1,067 mm) and 1,000 mm (3 ft 3 + 3 ⁄ 8 in) metre gauge – four rails must be used. Dual-gauge rail lines ...
Europe. Australia. A railway track (British English and UIC terminology) or railroad track (American English), also known as a train track or permanent way (often " perway " [1] in Australia), is the structure on a railway or railroad consisting of the rails, fasteners, railroad ties (sleepers, British English) and ballast (or slab track), plus ...
Track gauge. Track geometry is concerned with the properties and relations of points, lines, curves, and surfaces [1] 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 ...
Track ballast is the material which forms the trackbed upon which railroad ties (UK: sleepers) are laid. It is packed between, below, and around the ties. [1] It is used to bear the compression load of the railroad ties, rails, and rolling stock; to facilitate drainage; and keep down vegetation that can compromise the integrity of the combined ...
