Comparison of different gauges common in India with standard gauge which is not common in India

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

Indian Railways currently has significant lengths of 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 length of track used by Indian Railways was about 115,000 km (71,000 mi) while the total route length of the network was 65,000 km (40,000 mi) in 2011.^[1]

Heritage lines that will not be converted

A single metre-gauge line and four narrow-gauge lines on which heritage trains run in hilly regions will not be converted to broad gauge. These are:

Name of heritage railway line	Gauge mm	Track km	State	from (plains)	to (hills)
Nilgiri Mountain Railway	1,000 mm	46	Tamil Nadu	Mettupalayam/MTP	Udagamandalam (Ooty)/UAM
Kalka–Shimla Railway	762 mm	94	Himachal Pradesh	Kalka/KLK	Shimla/SML
Kangra Valley Railway	762 mm	164	Himachal Pradesh	Pathankot/PTK	Joginder Nagar/JDNX
Darjeeling Himalayan Railway	610 mm	79	West Bengal	New Jalpaiguri/NJP	Darjeeling/DJ
Matheran Hill Railway	610 mm	20	Maharashtra	Neral/NRL	Matheran/MAE
Total:		395

A demand has been made to convert Pathankot-Dharamshala-Joginder Nagar railway line into broad gauge but no decision has been taken.^[3]
