Siliguri started as a small area i.e. now Saktigarh, southern part of city, on the bank of Mahananda River. Treaty of Sugauli in 1815 signed between Britain-Nepal, changed the prospect of Siliguri. As it became a point of transit with Darjeeling hills and Nepal mainland. 1815 onwards, Siliguri started growing rapidly as a small city due to its strategic convenience of trade. In 1865, the British captured Darjeeling and the entire Dooars region to build tea plantations and export the produce to England. For easy exportation they introduced the Siliguri Town railway station which stands to this day, and introduced the Toy train from the station to Darjeeling in 1880. This helped Siliguri gain sub-divisional town status in 1907.
