The Pacific Railway Act of March 3, 1863, specified that the federally funded transcontinental railroad was to use standard gauge, which helped to further popularize it among American railroads, although the standard gauge was already in use on many other lines prior to 1863.
The vast majority of North American railroads are standard gauge (4 ft 8 + 1 ⁄ 2 in / 1,435 mm).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.
Standardized in East German NORMAT model railway standard collection. Z0 was originally introduced in Czechoslovakia in 1938. 35 mm: 1:30: 35 mm (1.378 in) 35 mm was in use in the 1930s and 1940s by several model railway manufacturers in Japan. 35 mm was introduced in the 1930s. Late 1940s 35 mm was replaced by O gauge. No. 2: 1:27: 2 in (50.8 mm)
The most common use of the term "track gauge" refers to the transverse distance between the inside surfaces of the two load-bearing rails of a railway track, usually measured at 12.7 millimetres (0.50 inches) to 15.9 millimetres (0.63 inches) below the top of the rail head in order to clear worn corners and allow for rail heads having sloping ...
There are also some extreme narrow gauge railways listed. See: Distinction between a ridable miniature railway and a minimum gauge railway for clarification. Model railway gauges are covered in rail transport modelling scales. Train with model Southern Railway Schools class. Triple-gauge pointwork (3 + 1 ⁄ 2 in, 5 in, and 7 + 1 ⁄ 4 in) on ...
Rail Baltica: Standard-gauge Rail Baltica railway is under construction and is scheduled to be completed by 2026. Cost studies have been undertaken for a potential overhaul of entire rail network to standard gauge. [41] Ethiopia: Addis Ababa-Djibouti Railway; Addis Ababa Light Rail: 659 km (409 mi) Other standard gauge lines under construction ...
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 ...
A railway track (CwthE and UIC terminology) or railroad track (NAmE), also known as permanent way (CwthE) [1] or "P Way" (BrE [2] and Indian English), is the structure on a railway or railroad consisting of the rails, fasteners, sleepers (railroad ties in American English) and ballast (or slab track), plus the underlying subgrade.
