A standard-gauge railway is a railway with a track gauge of 1,435 mm (4 ft ... one of the key issues was the track gauge (the distance, or width, ...
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 ...
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.
In 1886, the southern railroads agreed to coordinate changing gauge on all their tracks. After considerable debate and planning, most of the southern rail network was converted from 5 ft (1,524 mm) gauge to 4 ft 9 in (1,448 mm) gauge, then the standard of the Pennsylvania Railroad, over two days
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.
The minimum track spacing can be derived from the loading gauge. The European Berne Gauge has a width of 3,150 mm (10 ft 4 in). The minimal distance to structures on the side of the track is half of it but that is doubled again for double track lines. As the carriage can sway and bounce within the rail gauge, one adds 100 mm (3.9 in) and with a ...

03-VM: 4,280 mm height, 3,150 mm width; The standard defines static envelopes for trains on the national network as T, T c and T pr. The static profile 1-T is the common standard on the complete 1520 mm rail network including the CIS and Baltic states. The structure clearance is given as S, S p and S 250. There is a tradition that structure ...
