SIKKIM - Info & Snippets


* 3 Apr 2026 
Sikkim - the only state currently without railway connectivity
The Sivok-Rangpo railway project is an effort by the Indian Railways to link the state of Sikkim with the national rail system for their first time. This challenging venture covers 44.98 kilometers and will connect Sivok in West Bengal with Rangpo in Sikkim, passing through beautiful mountains and valleys along its route. The Sivok-Rangpo railway project is carried out by the Northeast Frontier Railway zone together with IRCON International Limited, which used to be called Indian Railways Construction Company Limited. The train track will have five stops on its way: these are Sivok, Riyang, and Teesta Bazaar in the state of West Bengal; also, Melli and Rangpo which are located in Sikkim.
The Sivok-Rangpo train project will pass through difficult land, including the Mahananda Wildlife Sanctuary and various forest areas like Kurseong, Darjeeling, Kalimpong, and East Sikkim. This railway track will have 19 bridges and 14 tunnels; these tunnels make up about 38.55 kilometers which is almost 85% of the entire route. The longest tunnel will measure 5,270 meters, while the shortest will span 538 meters.
This train line will link to the Nathu La pass, which is a key point on the border between Sikkim and China.
The Teesta Bazaar railway station is a key part of the Sivok-Rangpo railway project. It’s going to be India’s first big underground station in high places and partly mountain areas. This station will have a platform that is 620 meters long, so it can hold an entire train with all its carriages. Additionally, the station will have six access tunnels for emergencies and evacuations.
