Punjab Northern State Railway
Punjab Northern State Railway(PNSR)
The route of what became the PNSR, was first surveyed in 1857 and years of political and military debate followed as described under Lahore & Peshawar Railway .
Finally, following further exchanges, the line was constructed by the of 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 first section of the line was opened in 1873 and Lahore and Peshawar were connected in 1883  with the completion of the Attock Bridge over the river Indus. It was the first railway in India to have been taken under GOI control in 1886.
The ‘1871-72 Report on Railways’  states:-
“Having been originally designed for the 5' 6"gauge (BG), fresh plans and drawings had to be prepared when it was determined to adopt the new metre gauge of 3' 3 3/8" (MG) This led to the suspension of operations for a time, but during the past year there has been much activity in pushing on the works, and considerable progress has been made. It is estimated approximately that the line will be constructed for 10,000/. a mile. The expenditure had amounted on the 31st December last to 660,868/. The bridges over the Ravee(Ravi), Chenab, and Jhelum rivers are amongst the most formidable works yet undertaken in India, and will not be finished so soon as the rest of the line, but the sections between the rivers may possibly be opened this year.”
- Lahore via Lala Musa to Jhelum Section. This first section of 103 miles(165km) of the PNSR opened in stages from Sept 1873  to Sept 1876  as a metre gauge (MG) line in accordance with Government Railway Gauge policy at the time (See separate page ‘Railway Gauge’ ). This policy was reversed in Jan 1874 and the conversion of this section to broad gauge(BG) was completed in 1878 . During the conversion this remained an ‘open line’ whilst the earthworks and bridgework were undertaken to permit the wider gauge 
- Jhelum to Rawalpindi Section. This section of the PNSR opened as a BG line in 1880 with a length of 70½ miles(113km), using temporary diversions allowing 1 in 50 gradients. Later from 1888 to 1897 a series of realignments improved the gradient to 1 in 100, giving a line length of 76¾ miles(121km)
- Rawalpindi to Peshawar Section . The surveys for this extension commenced in 1876-77 with three plans and estimates submitted as far as Attock. The final section to Peshawar was submitted in 1877-78. The first section from Rawalpindi opened in 1881 and extended in stages to reach Peshawar in 1883 .
- Ravi Bridge(marked R on map), over the River Ravi situated between Sadiq Pura, Lahore and Shahdara Bagh. The construction work on this bridge was started in 1871 to MG designs , opened 12 Apr 1875 and remained open during the BG conversion, which required bridge strengthening. The BG line opened 6 Oct 1878 between [[Lahore]) and Jhelum.
- Chenab/Alexandra Bridge(marked C on map), over the River Chenab between Wazirabad and Gujrat . Construction started in 1871 as MG and opened 22 Jan 1876 by Edward VII the King-Emperor when he was Prince of Wales. Converted to BG , which required alterations to the longitudinal bearers and opened 6 Oct 1878 between [[Lahore]) and Jhelum.
- Jhelum Bridge(marked J on map), over the River Jhelum , started in 1871 and opened 14 Sep 1876 taking the MG line to Jhelum. Converted to BG , which required alterations and opened 6 Oct 1878 between [[Lahore]) and Jhelum.
- Attock Bridge(marked A on map), over the River Indus between Attock and Khairabad. The construction started in 1880 and completed in 1883
Minor Bridges mentioned in the 1876-77 Report :- Chikori Bridge, which had to be rebuilt; Chumb Bridge, 5 openings of 37' 6' girder; Dekh Bridge, 3 openings of 37' 6' girder; Ghilanwala Bridge, 4 openings. The 1877-78 Report refers to the Bagh Butcha Bridge and the Chikori Nullah Bridge with the problems of conversion to the BG specification. The 1878-79 Report details the Jhelum to Rawlpindi Section with bridges over the large rivers Dina, Bukrala, Sohawa, Bishendorh, Bykhan and Sohan.
- Lala Musa -Mayo Salt Mines Railway - see separate page. Branch line, metre gauge. In August 1878 orders were received to proceed with the works of this line on a project prepared in the year 1872.
