Project Unigauge is an ongoing exercise of the Indian Railways to standardize most of the rail gauge in India towards a single 1676 mm (5 ft 6 in) wide broad gauge network.

India currently has significant quantities of four different incompatible gauges. The railways consist of around 42,000 km of broad gauge (BG) railway, 17,000 km of metre gauge (MG) and an assortment of narrow gauge lines.
 Early History
The project started around 1980. It was concluded that towns and cities on the meter (MG) and narrow gauge (NG) lines had a poorer service than equivalent towns on the broad gauge system. Conversion of lines to broad gauge would make the broad gauge more efficient, avoiding the current break of gauges, and with more capacity, with many regauged links providing short cuts for broad gauge traffic.
 Weight of Rail
An alternative way to reduce construction costs during conversion is to use lighter track and lighter rails. Railway rails are expensive and lighter rails achieve significant cost savings.

Lighter rails can only carry lighter engines and rolling stock, but since traffic is generally less, this is not a problem. Light engines can travel on heavy main lines, but not vice versa. If needs be light track can be gradually upgraded to heavy duty track. An intermediate stage is to allow heavier engines to operate on lighter track at reduced speed.
