Bahawalnagar–Fort Abbas Branch Line (Urdu: {{Nastaliq|بہاولنگر–فورٹ عبّاس فرعی ریلوے خط) was one of several branch lines in Pakistan, operated and maintained by Pakistan Railways. The line began at Bahawalnagar Junction and ended at Fort Abbas. The total length of this railway line is 84km (52miles) with 4 railway stations.[2]
The branch line was initially referred to as the Bahawalnagar-Fort Abbas Railway and was a Darbar line financed by the Princely Bahawalpur State. The line opened in 1928 as part of the North Western State Railway network.[3] The line was owned by the Bahawalpur State Darbar, who also owned the Khanpur–Chachran Railway, and formed an important part of the NWR network. Following Pakistan's independence, the line became part of the Pakistan Railways network.
