A railroad right-of-way (easement) width varies based on the terrain, with a 100 feet (30 m) width being ample enough where little surface grading is required. [40] The initial 705 miles (1,135 km) stretch of the Illinois Central Railroad is the most liberal in the world with a width of 200 feet (61 m) along the whole length of the line. [41]
Standard gauge railway lines made a return in 2014 on experimental railway line in Aceh. The railway tracks of Java and Sumatra use 1,067 mm (3 ft 6 in). Iran: Islamic Republic of Iran Railways: 12,998 km (8,077 mi) Iraq: Iraqi Republic Railways: 485 km (301 mi) Ireland Transport Infrastructure Ireland: Luas in Dublin: Israel
The world's first operational mountain-climbing cog railway (rack-and-pinion railway), the Mount Washington Cog Railway in Coos County, New Hampshire — in operation since its opening in 1869 — uses a 4 ft 8 inch (1,422 mm) rail gauge, as designed by Sylvester Marsh, the creator of the Marsh rack system for ensuring firm traction going up ...
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 possible displacement of tracks over time one adds some 250 mm ...
Height of rail equaled width of foot for each ASCE tee-rail weight; and the profiles specified fixed proportion of weight in head, web and foot of 42%, 21% and 37%, respectively. ASCE 90 lb/yd (44.6 kg/m) profile was adequate; but heavier weights were less satisfactory.
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 May 31, 1886. Over a period of 36 ...
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 ).
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 ...
