Bannu–Tank Branch Line

The total length of this railway line was 122 km with 7 railway stations. It was known by locals as "choti rail", since it was the only narrow gauge railway in the country  (excepting the stretch from Kohat Tehsil to Thal pre-1991) The line was dismantled in 1995.

History

The line was then further extended in 1916 to reach Tank Junction station. The line was also sometimes referred to as the Mari Indus Railway.
