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.
