Why is Karachi a major terminus in Pakistan's railway system?

Karachi serves as a major terminus in Pakistan's railway system primarily due to its status as the country's principal seaport and its historical role as the gateway to the Indus River valley and the Punjab region.12

The city's importance as a rail hub developed alongside its growth as a commercial and industrial center. In the 19th century, the British expanded the railway network to connect the port directly to the hinterland, eventually linking it to the Delhi-Punjab system at Multan by 1878. Today, Karachi remains the starting point for the country's main rail route, which extends more than 1,000 miles north to Peshawar via Lahore and Rawalpindi.23

Functionally, the railway system is vital for transporting goods between the port and the interior of the country. Additionally, a circular railway facilitates commuter traffic and the movement of freight between the port and Karachi's various industrial areas.4
