Indian Branch Railway
The Indian Branch Railway (IBR) was formed in 1862 to construct short branches and feeder lines in northern India, with a 20-year subsidy from the Government of India(GoI) but no guarantee.
In 1863, the IBR built the Nalhati-Azimganj Railway. The line used a 4ft(1222mm) unique rail gauge. The Nalhati to Azimganj line was taken over by the Government in 1872, and by this time named as the Nalhati State Railway.
In 1866, it began construction of a Metre Gauge(MG)) line between Lucknow-Kanpur, completed the following year. Without a guaranteed return from the Government of India(GoI), the IBR found it impossible to continue and in 1867, secured a new contract from the GoI on terms similar to those on offer in the 1850s i.e. a guaranteed return on capital employed.
