[9][10] Maharaja Ranbir Singh (r. 1830–1885) wrote to the Governor General of India with a proposal offering to fund its construction, which was agreed.

However, this clause was cancelled in the supplementary agreement, and the Punjab section of the line was funded by Government of India instead.

[17] The Jammu and Kashmir state border crossed the line 0.26 miles (0.42 km) east of Suchetgarh station.

The government of Maharaja Hari Singh made a standstill agreement with Pakistan for continuance of all the pre-existing arrangements.

[19] 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.

[7] In June–July 1948, when there was a pause in the fighting of the Kashmir War after the arrival of the UNCIP, the Indian Army Corps of Engineers used the steel rails of the railway to repair sections of roads damaged by the Pakistani forces.

In 2000, the old Jammu (Bikram Chowk) railway station was demolished to make way for an art centre.

[24] A detailed survey in December 2013 by Pakistan Railways showed that the line is unusable and would require billions of rupees to repair and potentially run trains from Jammu to Lahore and further into Amritsar.
