This blog describes about "Project Unigauge" in detail which is an ongoing exercise by Indian Railways to convert most of the rail gauges in India(i.e Narrow Guage,Meter Guage) 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.

mass rapid transport systems (metro rail) built or being built in six large cities in India use both 1,676 mm (5 ft 6 in) broad gauge and 1,435 mm (4 ft 8 1⁄2 in) standard gauge. However these metro railways are independent corporations not under the jurisdiction of Indian Railways and therefore Project Unigauge does not apply to them.
A broad-gauge network allows bigger trains, higher speeds, and more stability. However, it costs more than smaller gauge. For India, which has one of the world's highest population densities, broad-gauge allows comfortable travel for high volumes of travellers, and is deemed to be economically feasible in the long term.
The following Heritage lines that will not be converted to Broad Guage under
"Project Unigauge"
One metre gauge and four narrow gauge tracks on which heritage trains run in hilly regions will not be converted to broad gauge under "Project Unigauge".
These are as follows:
Nilgiri Mountain Railway
Kalka–Shimla Railway
Kangra Valley Railway
Darjeeling Himalayan Railway
Matheran Hill Railway
