From WikiPedia: The Jammu–Sialkot line was a 43 km (27 mi) narrow gauge branch of the North Western State Railway from Wazirabad Junction, Punjab, to Jammu through Sialkot Junction. It was built in 1897, and was the first railway line in the state of Jammu and Kashmir. It was dismantled after the partition of India, with a replacement line built from Pathankot to Jammu.
