Karachi–Peshawar Line

Karachi–Peshawar Railway Line (Urdu: کراچی–پشاور مرکزی ریل راستہ, romanized: karāčī-pešāvar markazī rēl rāsta) (also referred to as Main Line 1 or ML-1) is one of four main railway lines in Pakistan, operated and maintained by Pakistan Railways. The line starts from Kiamari station in the province of Sindh and ends at Peshawar Cantonment Station in Khyber Pakhtunkhwa province. The railway track is dual between Keamari and Shahdara Bagh, Chaklala and Golra Sharif. The total length of the line is 1,687 kilometers (1,048 mi), with 173 railway stations in between. The line serves as the country's main passenger and freight line with 75% of the country's cargo and passenger traffic passing through yearly.

In 2016, funding for a six-year US$6.8 billion upgrade and renovation project was agreed as part of the China Pakistan Economic Corridor, with the average speed expected to be doubled to 140 kilometers per hour upon completion. The project has been delayed several times since then.
