A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge narrower than 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge. Most narrow-gauge railways are between 600 mm ( 1 ft 11 + 5 ⁄ 8 in ) and 1,067 mm ( 3 ft 6 in ).
[18] [19] The Colorado Railroad Museum established in 1959, operates a demonstration loop of narrow gauge track in Golden, Colorado. [20] Stereograph of Utah's American Fork Railroad in the 1880's. In Utah, three foot gauge narrow-gauge railroads sprang up immediately after the completion of the Transcontinental Railroad on May 10, 1869.
However, the country began to rebuild and fix existing tracks in anticipation for new train service. FENADESAL currently uses the tracks to connect the capital city of San Salvador to its suburbs. There are now more plans to start a metro rail on the current tracks, making it the most effective narrow-gauge train tracks in Central America.
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 beginning on Monday, May 31, 1886.
The sharpest curves tend to be on the narrowest of narrow gauge railways, where almost all the equipment is proportionately smaller. [4] But standard gauge can also have tight curves, if rolling stocks are built for it, which however removes the standardisation benefit of standard gauge. Tramways can have below 100-foot (30 m) curve radius.
The JR N700 Series Shinkansen, the first tilting train on Japan's high speed network. A high-speed tilting train is a tilting train that operates at high speed, typically defined as by the European Union to include 200 km/h (124 mph) for upgraded track and 250 km/h (155 mph) or faster for new track.
Measuring rail gauge. During the early days of rail, there was considerable variation in the gauge used by different systems, and in the UK during the railway building boom of the 1840s Brunel's broad gauge of 7 ft 1 ⁄ 4 in (2,140 mm) was in competition with what was referred to at the time as the 'narrow' gauge of 1,435 mm (4 ft 8 + 1 ⁄ 2 in).
An L0 Series trainset, holding the non-conventional train world speed record of 603 km/h (375 mph) TGV 4402 (operation V150) reaching 574.8 km/h (357 mph). The world record for a conventional wheeled passenger train is held by a modified French TGV high-speed (with standard equipment) code named V150, set in 2007 when it reached 574.8 km/h (357.2 mph) on a 140 km (87 mi) section of track.
