Comparison of different gauges in India with standard gauge. Project Unigauge, started on 1 April 1992, [1] is an ongoing effort by Indian Railways to convert and unify almost all rail gauges in India to 1,676 mm (5 ft 6 in) broad gauge.
5 ft 6 in (1,676 mm) is a broad track gauge, used in India, Pakistan, western Bangladesh, Sri Lanka, Argentina, Chile, and on BART (San Francisco Bay Area). In North America, it is called Indian, Provincial, Portland, or Texas gauge. In Argentina and Chile, it is known as "trocha ancha" (Spanish for "broad gauge").
Some amount of tolerance is necessarily allowed from the nominal gauge to allow for wear, etc.; this tolerance is typically greater for track limited to slower speeds, and tighter for track where higher speeds are expected (as an example, in the US the gauge is allowed to vary between 4 ft 8 in (1,420 mm) to 4 ft 10 in (1,470 mm) for track ...
Railways with a track gauge between 500 mm (19 + 3 ⁄ 4 in) and 4 ft 8 + 1 ⁄ 2 in (1,435 mm) standard gauge. Diamond crossing dual gauge double line narrow-gauge and standard-gauge. Narrow gauge track.
Track gauge conversion is the changing of one railway track gauge (the distance between the running rails) to another. In general, requirements depend on whether the conversion is from a wider gauge to a narrower gauge or vice versa, on how the rail vehicles can be modified to accommodate a track gauge conversion, and on whether the gauge conversion is manual or automated.
Despite attempts to convert the entire country into broad-gauge many Metro systems and Mumbai–Ahmedabad high-speed rail corridor are done under Standard-gauge railway. [ 1 ] In 2007, India had 45 narrow-gauge lines in operation and most of these lines were made in pre-independence era predominantly in territories controlled by Princely states ...
