Northeast India by train and bus only, the railhead map and bus reality
Quick answer: You can reach every Northeast state by train + bus + shared taxi, and some of the best trips run exactly this way. The five railheads that matter: Dimapur (Nagaland), Naharlagun (Arunachal/Ziro), New Jalpaiguri (Sikkim), Silchar (Barail valley/Mizoram route) and Agartala (Tripura). Buses and shared Sumos do the last miles. What trains can’t do: the valleys beyond the roads, that’s the honest limit.
The railhead map
- Dimapur (Nagaland), the region’s busiest tourist railhead: Guwahati/Kolkata/Delhi trains daily, then 3h of shared Sumo to Kohima. Every Hornbill trip starts here.
- Naharlagun (Arunachal), the Ziro gateway: overnight trains from Guwahati/Kolkata, then shared taxis 3–4h up to the Apatani valley (Ziro guide).
- New Jalpaiguri (Sikkim + Darjeeling side), NJP feeds Gangtok (4h), Pelling and the hills; helicopters for the impatient.
- Silchar (southern Assam), the Barail line: Haflong’s hill section, and the road onward to Aizawl or Agartala.
- Agartala (Tripura), fully on the Indian rail map now, including a link toward Aizawl-side. Unakoti, Neermahal and the Jampui Hills all run off it (Tripura guide).
The bus reality
Assam’s ASTC network is genuinely good: Guwahati ↔ every major town, overnight options on long routes. State buses connect state capitals; shared Sumos (not buses) handle the last hundred kilometres almost everywhere. Night buses exist on Guwahati–Silchar and Guwahati–Agartala corridors. Book day-before at the stands or on state portals; hill routes rarely sell out except festival weeks.
The all-public-transport trip that actually works
Guwahati in → bus to Shillong → shared cabs (Sohra/Nongriat/Dawki) → bus back → train to Dimapur → Sumo to Kohima → Hornbill (or a package when you want a bed guaranteed) → train onward to Naharlagun → Ziro → out via Guwahati. Two-plus weeks, five states, zero self-drive.
The limit, stated plainly
Beyond the railheads and bus towns, trains stop and you need wheels: Dzükou trailheads, Mechuka, Anini, Mon. Those legs = shared Sumos with early starts, or operator legs. Maps mislead on timings, keep buffers (why).
