This railway connected Quetta to the Indus Plains and Bolan Pass
The Bolan Railway was built in the 1880s to connect Sibi with Quetta, Balochistan's capital. In the 1890s it was extended to Chaman, on the southern Afghan frontier. The British had hoped to extend it to nearby Kandahar, but the Amir of Afghanistan, understanding this as a threatening imperial move, forbade the railway's extension. It was never completed.
Th is photograph was taken by Fred Bremner, the premiere photographer of British Baluchistan who followed the construction of railway lines and tunnels throughout the province with his camera. He had studios in Quetta and Lahore and worked in what is now Pakistan from 1889 until 1923.
