The short answer people are searching for: no, there is no train to Sikkim yet. The state has never had a railway station. Today you reach Sikkim by flying to Bagdogra (IXB) or taking a train to New Jalpaiguri (NJP), both near Siliguri in North Bengal, then driving four to five hours up into the hills. But that is changing. India is building Sikkim's first-ever railway, the Sivok-Rangpo line, and it is far enough along that it is worth understanding before you plan a trip.
What is being built: the Sivok-Rangpo line
The Sivok-Rangpo line is a 45 km railway from Sivok in North Bengal (on the existing network near Siliguri) to Rangpo, the border town where you cross into Sikkim. When it opens, Rangpo becomes Sikkim's first railway station. It is an extraordinary piece of engineering: most of the route runs through the Himalayan foothills in tunnels, including one of the more unusual stations in India built partly underground.
| Feature | Detail |
|---|---|
| Route | Sivok (North Bengal) to Rangpo (Sikkim border) |
| Length | About 45 km |
| Stations | 5, including Teesta Bazaar built partly underground |
| Tunnels | 14 tunnels covering roughly 86% of the route |
| Longest tunnel | About 5.3 km |
| Major bridges | 13 |
| Progress (2026) | About 77% physically complete |
| Target completion | December 2027 (official target) |
When will it actually open?
The official target is December 2027, and the project was about 77% physically complete through 2026. That is real progress, but be realistic. This is tunnelling through young, unstable Himalayan rock in a high-rainfall, landslide-prone belt. The same terrain that makes the road drive slow makes the railway slow to build. Earlier target dates have already moved. Our honest read for anyone planning a trip: do not build travel plans around catching this train before 2028 at the earliest, and watch for confirmed commercial-service announcements rather than completion-of-construction headlines, which are not the same thing.
Will the train reach Gangtok? And Nathula?
Not in the first phase. Sivok-Rangpo only reaches Rangpo, the border town. From Rangpo you would still drive about two hours up to Gangtok. A second phase, a roughly 18 km Rangpo-to-Gangtok spur, has had its final location survey completed, and over 90% of that route would also need to be tunnelled given the terrain. A later, more ambitious phase has been talked about extending the line towards Nathula on the China border. Both are future projects with no firm opening dates, so for the foreseeable future the railway gets you to the edge of Sikkim, not to Gangtok's doorstep.
What it means for your trip
For a trip in 2026 or 2027, nothing changes: you fly to Bagdogra or train to NJP and drive up, exactly as travellers have always done. When the Sivok-Rangpo line opens, the main benefits will be for travellers who prefer rail over flying, or who come from parts of India with good train links but poor air connectivity to Bagdogra. Reaching Rangpo by train removes the longest, most tiring stretch of the road journey from Siliguri, though you will still have the mountain drive from Rangpo up to Gangtok, Pelling or North Sikkim.
How to reach Sikkim right now
Until the railway opens, the two entry points are Bagdogra Airport (IXB) and New Jalpaiguri railway station (NJP), both near Siliguri. From either, it is about 4 to 5 hours by road to Gangtok, 5 hours to Pelling, and longer to North Sikkim. If you are coming by train from elsewhere in India, NJP is your railhead; it is one of the best-connected stations in the Northeast, with direct trains from Kolkata, Delhi, and much of the country. From NJP or Bagdogra we arrange the onward mountain transfer. See our guide on how to reach Gangtok and our distances and drive times reference for the full picture.
