The Kalka-Simla Railway (KSR) was a narrow gauge branchline, the final leg in the journey from Delhi via Umballa to the hill town of Simla, the summer retreat of the Viceroy and senior Government of India staff.
Originally built and worked by a private company, the line was opened in 1903 as a 2' 0" narrow gauge railway. Following the decision of the Imperial General Staffs to standardise, wherever possible, on a 2' 6" gauge, the track was so converted in 1905.
The KSR was taken over by the Government in 1906 and later worked by the North Western Railway.
The KSR remains one of the longest narrow gauge railway lines still operated by Indian Railways.
