Fazilka and
Hussainiwala on this line are two defunct railway border crossing points on the India–Pakistan border. Before partition of India in 1947, there were the long Delhi-Samma Satta and the long Delhi-Raiwind railway lines, which were operational. After partition of India, a line linked Amruka on the Pakistan side of the India–Pakistan border, opposite Fazilka, towards Samma Satta. The only train running through these tracks was withdrawn after 1965 war. The long Amruka-Samma Satta line and the long Kasur-Raiwind lines are operational in Pakistan now. The Hussainiwala–Ganda Singh Wala railway crossing, near Firozpur, became defunct with the partition of India. The broad gauge line from Kasur Junction in Pakistan has been closed. The strategically important Kaiser-E-Hind Rail cum Road Bridge was blown up during the
Indo-Pakistani War of 1971 at Hussainiwala, and was never rebuilt. In 2013, Sutlej Barrage Bridge on Hussainiwala was opened after restructuring. ==Electrification==
