How did the railway from Karachi to Kotri help the city develop?

The construction of the railway from Karachi to Kotri in 1861 was a pivotal development that helped transform Karachi from a local fishing village into a major commercial hub. By linking the city to the Indus River region, the railway facilitated the movement of goods and established a vital connection between the port and the interior.1

This infrastructure served as a foundational step toward integrating Karachi with the broader hinterland. The line was later extended in 1878 to join the Delhi-Punjab railway system at Multan, which allowed Karachi to serve as the primary outlet for the Punjab region as it emerged as a major agricultural producer. These improvements in connectivity were instrumental in Karachi’s rise, eventually leading it to become the largest grain-exporting port of the British Empire by 1914.1
