Project Unigauge

Project Unigauge is an ongoing exercise by Indian Railways to standardize most of the rail gauges in India to 1,676 mm (5 ft 6 in) broad gauge.

Indian Railways currently has four different gauges: the 1,676 mm (5 ft 6 in) broad gauge, the 1,000 mm (3 ft 3+3⁄8 in) metre gauge, and two narrow gauges 2 ft 6 in (762 mm) and 2 ft (610 mm). The total track length used by Indian Railways is 115,000 km (71,000 mi) while the total route length of the network is 66,030 km (41,030 mi) in 2015.^[1]
