Indian Railways uses four rail gauges: 1,676 mm (5 ft 6 in) Broad Gauge (BG) (Indian gauge), 1,000 mm (3 ft 3+3/8 in) Metre Gauge (MG) and two Narrow Gauges, 762 mm (2 ft 6 in) and 610 mm (2 ft) . Project Unigauge seeks to standardise the rail gauges in India by converting most of metre gauge tracks and narrow gauges tracks to broad gauge track. Some narrow gauge tracks on which heritage trains run in hilly regions (Simla, Darjeeling, Ooty, Kangra and Matheran) will not be converted. Delhi Metro Rail Corporation has constructed 1,435 mm (4 ft 8+1/2 in) Standard Gauge in Delhi and started running metro trains in Delhi city in 2010. Delhi Metro is a separate urban mass rapid transit system not owned by Indian Railways.
