Lahore & Peshawar Railway
The Lahore & Peshawar Railway in the Punjab was first surveyed in 1857-58 by deployment of a team of Engineers from the Sind Railway Company . The construction did not proceed and years of political and military debate followed.
There was no further progress until 1866 when the military logistics of the Punjab was being considered. A letter  from Cranbourne to Lawrence carries the following IOR Contents note:- ' ..proposes to suspend work on Peshawar barracks, pending construction of Lahore-Peshawar railway, and in view of unhealthiness of area, cost, and uncertainty regarding number of troops required to be stationed there; asks whether Peshawar valley could be held with native troops in ordinary times; Council divided whether railway should be built by Govt or Guaranteed Company;...'
Finally, following further exchanges, as can be seen from the IOR Records, in 1868 a team of Government of India(GoI) appointed Engineers (see ‘Personnel’) commenced construction.
Political and military debate continued even once construction had begun  as see in the IOR Contents note:- ‘Need for early decision on gauge of Indus Valley railway line since it impinges on question whether Lahore-Peshawar line should be standard or narrow gauge; outlines arguments for narrow gauge on both these lines including military implications; asks Argyll to see Col Strachey on subject’.
Following further exchanges, the line was constructed by the of Government of India(Government of India(GoI). The Punjab Northern State Railway(PNSR) was created in 1870-71 to construct and operate the railway from Lahore to Peshawar.

The BG line from Lahore to Jhelum, 103 miles(166km), opened 1878, thus taking the BG line north-eastward to Rawalpindi and reaching the Indus river in 1881. The line from Peshawar had reached the left bank of Kiarabad on the left bank of the Indus river in May 1882.
Lahore and Peshawar , 468 miles(753 km), were finally connected in 1883  with the completion of the Attock Bridge over River Indus and became the Punjab Northern State Railway (PNSR). The PNSR was transferred to the newly formed Railway Board, becoming the first railway in India to be nationalised the under the control of the Government of India(GoI). Shortly after, on 1 Jan 1886, the North Western Railway (NWR) was formed from the amalgamation of the PNSR with others.
