A map from 1939 that shows the route of Dibru-Saiya railway

The 19th century Survey of India maps show a Railway line that looks like a small reclining Y. It carries the title Dibru-Sadiya Railway (DSR). The cause and construction of this totally isolated little railway is illustrative of the zeal of our pioneering forebears and is an early example of user initiative in project-specific rail connectivity.
