The first train to Jammu from Sialkot, 1890.
The Jammu–Sialkot line was a 43 km (27 mi) broad gauge branch of the North Western State Railway from Wazirabad Junction, Punjab, to Jammu, passing through the Sialkot Junction.
The section from Sialkot to Jammu (Tawi) was 27 miles (43 km) long, partly in the British Indian province of Punjab and partly in the princely state of Jammu and Kashmir Built in 1890 during the reign of Maharaja Pratap Singh, it was the first railway line in the state of Jammu and Kashmir connecting Jammu-Amritsar via Lahore.
The railway line ran till 18 September 1947, when the newly made Pakistan, which inherited the North Western State Railway from united India, suspended the train service.The railway line fell into disrepair.A new line between Pathankot and Jammu was built by Indian Railways in 1972.
The government of Maharaja Hari Singh made a standstill agreement with Pakistan for continuance of all the pre-existing arrangements.
However, the railway service was suspended by Pakistan on or about 18 September 1947.The act was regarded as a violation of the standstill agreement by Jammu and Kashmir. It also created hardships for the Jammu Muslims who wanted to find safety in Sialkot in the midst of increasing communal tension in Jammu.
With the state's accession to India on 26 October and the ensuring Kashmir war between the two Dominions, the suspension of the railway line became permanent. The train service was never resumed.
