The Quetta–Taftan Line, also known as Spezand–Zaheden Railway Line (also referred to as Main Line 4 or ML-4) is one of four main railway lines in Pakistan, operated and maintained by Pakistan Railways. Inward from Pakistan's most western edge, it begins at Spezand Junction and has services that continue beyond Koh-e-Taftan station in high mountains, west. Its length is 732 kilometers (455 mi) to the Iranian border, a few kilometers further west of that station. It has ten active stations, of which seven are in Pakistan and three are in Iran. Many or all primary services since 1940 (and 1922 to 1931) terminate on the natural continuation in eastern Iran at the high city of Zahedan, which sees a change of gauge (of track and rolling stock) for accessing the Trans-Iranian Railway. This section is difficult to maintain due to Nushki Desert and Mountain Ranges.
