Railway Network of Northeast India: State-wise Railways, Major Lines, Stations, Projects & Map
The railway network in Northeast India connects river valleys, foothill towns, commercial centres and an increasing number of destinations in the surrounding hill states. Assam forms the main connecting network, while branch lines and newer extensions provide access to Arunachal Pradesh, Meghalaya, Nagaland, Manipur, Mizoram and Tripura. Sikkim’s first railway connection remains under construction in the official records reviewed for this guide.
Understanding railways in Northeast India requires more than a list of stations. A railway may enter a state without reaching its capital. A completed track section may not yet have a regular passenger service. Similarly, a survey or announced completion target does not mean that a route is open.
This guide separates established railway corridors, commissioned extensions, unfinished capital-connectivity projects and proposals at the survey stage. It covers all eight northeastern states, including Sikkim alongside the Seven Sisters.
For the geographical background, read our guide to the geography, physiography and economy of Northeast India .
Railway connectivity in Northeast India: quick answer
- Assam contains the region’s principal railway junctions and connecting corridors.
- Naharlagun provides rail access to the Itanagar capital area of Arunachal Pradesh.
- Agartala is connected by broad-gauge railway, with the line continuing south to Sabroom.
- Sairang has served the Aizawl area since the Bairabi–Sairang line opened on 13 September 2025.
- Mendipathar gives Meghalaya an operational railway connection; this is not a railway connection to Shillong.
- Imphal and Kohima should not be shown as completed railway destinations on the basis of older project deadlines.
- Sivok–Rangpo is intended to provide Sikkim’s first railway connection. Rangpo and Gangtok are different places.

Northeast Frontier Railway: Headquarters and Divisions
Northeast Frontier Railway, commonly abbreviated as NFR or N.F. Railway, is the Indian Railways zone responsible for the main railway network serving the northeastern region. Its headquarters is at Maligaon, Guwahati. [1, 2]
Its administrative area also extends into parts of West Bengal and Bihar. Consequently, a Northeast Frontier Railway map and a map showing only the eight northeastern states do not have identical coverage. Railway divisions follow operational requirements rather than state boundaries.
| Division | Divisional headquarters state |
|---|---|
| Katihar | Bihar |
| Alipurduar | West Bengal |
| Rangiya | Assam |
| Lumding | Assam |
| Tinsukia | Assam |
Exam distinction: Northeast Frontier Railway, headquartered at Maligaon, is different from North Eastern Railway, headquartered at Gorakhpur. The two names refer to separate railway zones. [2, 18]
State-wise Railway Network in Northeast India
The table below describes railway access rather than attempting to combine route-length figures from different reporting years. “Commissioned” refers to infrastructure status; passengers should separately confirm the services operating on their travel date.
Swipe horizontally on smaller screens to view the complete table.
| State | Established or commissioned railway access | Important stations or railheads | Capital-connectivity distinction |
|---|---|---|---|
| Assam | Extensive valley network with routes along both sides of the Brahmaputra and a hill connection to the Barak Valley. | Guwahati, Kamakhya, New Bongaigaon, Rangiya, Lumding, Badarpur, Silchar, New Tinsukia and Dibrugarh. | Dispur, the capital, lies within Guwahati’s urban area and is served through the city’s railway stations. |
| Arunachal Pradesh | Established access through Naharlagun and Bhalukpong. The Murkongselek–Sille extension received commissioning and safety-clearance reports in February 2026. | Naharlagun, Bhalukpong; newly commissioned Sille. | Naharlagun serves the Itanagar area. Sille is part of the separate project toward Pasighat. |
| Meghalaya | Dudhnoi–Mendipathar provides the established rail entry into the Garo Hills. | Mendipathar. | Shillong does not acquire a rail connection merely because Meghalaya has a railway station. |
| Nagaland | Dimapur lies on an established through route. Dhansiri–Shokhuvi and Shokhuvi–Molvom are commissioned sections of the capital-connectivity project. | Dimapur, Shokhuvi and Molvom. | The remaining line toward Zubza, serving the Kohima area, was still under construction in the June 2026 review. |
| Manipur | Rail access from Assam through Jiribam, with the Jiribam–Khongsang section commissioned. | Jiribam and Khongsang. | The onward project toward Imphal remained under construction in the August 2026 review. |
| Mizoram | The former Bairabi rail connection now extends to Sairang through the line inaugurated in September 2025. | Bairabi, Hortoki, Kawnpui, Mualkhang and Sairang. | Sairang serves Aizawl. The railway terminal and Aizawl city centre are not the same location. |
| Tripura | Broad-gauge corridor from the Assam side through northern Tripura to Agartala and onward to Sabroom. | Dharmanagar, Kumarghat, Agartala, Udaipur, Belonia and Sabroom. | Agartala has railway access within the capital city. |
| Sikkim | No commissioned in-state passenger railway connection was established in the official records reviewed. Sivok–Rangpo remains the first-link project. | New Jalpaiguri in West Bengal is an important external rail gateway; Rangpo is the project destination. | Reaching Rangpo will not mean that trains have reached Gangtok. |

Northeast India Railway Map: Simplified Route Schematic
The following schematic explains the main connections. It is not a geographical map or a complete station map: distances, direction and intermediate stops are simplified. Separate project sections are labelled so that unfinished routes are not mistaken for operating through lines.
Reading the schematic: Each arrow follows a railway corridor with intermediate stations omitted. It does not guarantee a direct train between every pair of places.
1. Western gateway and Assam
New Jalpaiguri / northern West Bengal → New Bongaigaon → Rangiya or Goalpara route → Kamakhya / Guwahati
Established corridors. New Jalpaiguri is in West Bengal, outside the eight-state northeastern region.
2. North-bank Assam and Arunachal access
Rangiya → Rangapara North → Harmuti → North Lakhimpur → Murkongselek
- Harmuti → Naharlagun: established branch.
- Rangapara North / Balipara → Bhalukpong: established branch.
- Murkongselek → Sille: newly commissioned/cleared section.
- Sille → Pasighat: onward project; full opening not verified here.
3. Upper Assam and Nagaland
Guwahati → Lumding → Dimapur → Furkating → Upper Assam routes toward New Tinsukia and Dibrugarh
A separate branch leaves the corridor at Dhansiri: Dhansiri → Shokhuvi → Molvom [commissioned]; onward toward Zubza [under construction].
4. Barak Valley, Manipur and Mizoram
Lumding → New Haflong → Badarpur → Katakhal → Silchar
- Katakhal → Bairabi → Sairang: established route into Mizoram.
- The branch toward Jiribam diverges at Arunachal Junction in Assam.
- Jiribam → Khongsang: commissioned; onward toward Imphal: under construction.
5. Tripura corridor
Badarpur → New Karimganj area → Dharmanagar
→ Kumarghat → Agartala
→ Udaipur → Belonia → Sabroom
Established domestic railway corridor.
6. Meghalaya’s existing connection
Dudhnoi, Assam → Mendipathar, Meghalaya
Established branch into the Garo Hills.
This route does not extend to Shillong.
7. Sikkim’s first railway-link project
Sivok, West Bengal → Rangpo, Sikkim
Under construction in the reviewed records.
Gangtok is not the endpoint of this project.
An official railway system map may also include sidings, freight facilities, gauge distinctions and lines under construction. Always check its legend and revision date before using it to identify a passenger route.
Major Railway Lines and Corridors
Assam’s western approach and Brahmaputra Valley routes
The western approaches connect Assam with the wider Indian railway system through northern West Bengal. Within western Assam, the routes through Rangiya and Goalpara provide different approaches toward the Guwahati area.
These connections are important because traffic destined for many northeastern states first uses part of Assam’s railway network. A disruption at a major junction or river crossing can therefore affect destinations beyond Assam itself.
The north-bank corridor
The Rangiya–Rangapara North–North Lakhimpur–Murkongselek corridor serves the northern side of the Brahmaputra Valley. Its branches provide access toward Naharlagun and Bhalukpong. The Bogibeel crossing adds an important connection with the Dibrugarh side of the river. [1, 13]
The Lumding–Badarpur hill corridor
The railway through Dima Hasao connects the Brahmaputra Valley network with the Barak Valley. It is especially important for access toward Silchar and the routes serving Tripura, Mizoram and Manipur.
The broad-gauge Lumding–Silchar corridor opened for goods traffic in March 2015 and passenger traffic in November 2015. This was a major change from the earlier metre-gauge system. [12]
Its route through rugged terrain becomes easier to understand alongside the geography of the Barail Range and Dima Hasao hills .
The Tripura north–south corridor
Tripura’s railway connects northern towns with Agartala and continues through southern Tripura to Sabroom. Agartala is therefore an intermediate city on a longer north–south rail corridor, rather than the endpoint of the state’s entire railway network. [16]
The Bairabi–Sairang extension
The 51.38 km Bairabi–Sairang line opened on 13 September 2025. Sairang provides a railway gateway close to Aizawl, while Bairabi remains part of the approach from Assam. Older descriptions presenting Bairabi as Mizoram’s only railway destination are now incomplete. [3]
Important Railway Stations in Northeast India
The following list identifies selected stations by their role. It is not a ranking by passenger numbers and does not include every station in the region.
| Station or station group | State | Importance |
|---|---|---|
| Guwahati and Kamakhya | Assam | Principal passenger gateways for the Guwahati urban area. |
| New Bongaigaon and Rangiya | Assam | Important junctions in the western and north-bank network. |
| Lumding | Assam | Key junction between Upper Assam-bound and Barak Valley-bound routes. |
| New Haflong | Assam | Important passenger access point in the Dima Hasao hill section. |
| Badarpur and Silchar | Assam | Major railway centres serving the Barak Valley. |
| New Tinsukia and Dibrugarh | Assam | Important passenger and commercial rail centres in Upper Assam. |
| Naharlagun | Arunachal Pradesh | Railhead serving the Itanagar capital area. |
| Mendipathar | Meghalaya | Established railway access in the Garo Hills. |
| Dimapur | Nagaland | Established through-line station and major gateway to Nagaland. |
| Jiribam and Khongsang | Manipur | Stations on the commissioned approach toward the Imphal project. |
| Bairabi and Sairang | Mizoram | Rail entry point and newer terminal serving the Aizawl area. |
| Agartala | Tripura | Railway station serving the state capital. |
| Dharmanagar, Kumarghat and Sabroom | Tripura | Important locations along the state’s north–south railway corridor. |
Rail Connectivity to the Northeastern State Capitals
Official capital-connectivity announcements sometimes use the name of a nearby terminal. For geographical accuracy, distinguish the capital, its serving station and any onward road journey.
- Dispur: served through railway stations in the Guwahati urban area.
- Itanagar: served by Naharlagun.
- Agartala: has railway access within the city.
- Aizawl: served by Sairang, with an onward road connection to the city.
- Kohima: the Dhansiri–Zubza project is intended to improve access to the capital area; the complete route is not established as open in the reviewed records.
- Imphal: the onward railway from the commissioned Jiribam–Khongsang section remains a construction project.
- Shillong: proposed capital access through the Byrnihat corridor should not be confused with the existing Mendipathar connection.
- Gangtok: Sivok–Rangpo is a first connection into Sikkim, not a completed railway to Gangtok.
New Railway Projects in Northeast India: Status and Scope
The table records the status supported by the dated sources reviewed. Project lengths are approximate where official documents use rounded or differing alignment figures. Target dates remain targets until an opening or commissioning notice confirms the relevant milestone.
| Project | Purpose | Verified status or latest evidence used | Important qualification |
|---|---|---|---|
| Bairabi–Sairang 51.38 km |
Rail access closer to Aizawl. | Opened on 13 September 2025; passenger and freight operations confirmed in the Ministry of Railways’ 13 September 2026 review. [3] | Completed line; Sairang serves Aizawl rather than lying in its city centre. |
| Jiribam–Imphal About 111 km |
Extend railway access into the Imphal Valley. | Jiribam–Khongsang commissioned; remaining sections under construction in the August 2026 review. [7, 8] | An inspection being planned for a section does not establish an opening of the whole line. |
| Dhansiri–Zubza / Dimapur–Kohima | Provide railway access toward the Kohima area. | The Nagaland government’s 15 June 2026 review confirmed Dhansiri–Shokhuvi and Shokhuvi–Molvom as commissioned; remaining stretches were under construction. [4] | The June review gives 78.42 km; other official summaries use approximately 82 km. These are source-specific figures. |
| Sivok–Rangpo About 45 km |
Provide Sikkim’s first railway connection. | Under construction. A 20 February 2026 Ministry of Railways release stated a December 2027 completion target; an August 2026 update still listed ongoing work. [5] | The target is not an opening guarantee. Rangpo is not Gangtok. |
| Murkongselek–Pasighat About 26–27 km |
Extend the Assam north-bank network into East Siang. | The roughly 15.6–15.7 km Murkongselek–Sille section was commissioned/cleared in February 2026. Full opening to Pasighat was not verified. [9] | Safety clearance and regular passenger-service introduction are separate milestones. |
| Tetelia–Byrnihat About 22 km |
Rail connection toward the Assam–Meghalaya border. | The Assam-side Tetelia–Kamalajari section is completed. Project records document constraints affecting the remaining link; full opening to Byrnihat was not verified in this review. [7, 10] | A partly completed Assam section does not establish completed access into the Khasi Hills. |
| Byrnihat–Shillong About 108 km |
Proposed capital connectivity for Meghalaya. | A sanctioned project with documented land and implementation constraints; no completed railway to Shillong was verified. [10] | Do not reuse an old projected completion year as a current opening date. |
| New Bongaigaon–Goalpara–Kamakhya doubling | Increase capacity on an existing Assam corridor. | Listed among ongoing works in the 13 March 2026 parliamentary reply. [11] | Doubling adds capacity; it is not a first railway connection. |
| Lumding–Furkating and Furkating–Tinsukia doubling | Strengthen the Upper Assam approach. | Both were listed as ongoing projects in March 2026. [11] | Existing trains do not imply that every doubling section is finished. |
| Saraighat bridge doubling and Kamakhya–Guwahati third line | Expand capacity around the Guwahati bottleneck. | Listed in the March 2026 project update. [11] | These are capacity works within an established railway area. |
| Sairang–Hbichhuah Survey scope: about 223 km |
Examine a further railway extension within Mizoram. | The March 2026 parliamentary reply records a sanctioned Final Location Survey for preparing a Detailed Project Report. [11] | Survey approval is not construction completion, an operating line or a railway connection into Myanmar. |
Agartala–Akhaura: infrastructure is not a passenger timetable
The Agartala–Akhaura cross-border rail-link inauguration took place on 1 November 2023. It is important for India–Bangladesh connectivity and potential regional logistics. [14]
However, an inauguration or an inaugural freight movement does not establish that travellers can book a regular international passenger train. Passenger operations, border procedures and current availability must be confirmed separately.
How the Railway Network Has Changed
Broad-gauge conversion
Gauge conversion replaced older metre-gauge sections with broad-gauge infrastructure, allowing through movement within the larger broad-gauge system. The Lumding–Silchar conversion was particularly significant because of its role in reaching the Barak Valley and the routes beyond it. [12]
Rail bridges across the Brahmaputra
The Brahmaputra is both a transport corridor and a major barrier to cross-valley movement. Railway bridges connect routes on opposite banks and influence the location of junctions and approach lines.
The Bogibeel rail-cum-road bridge, dedicated to the nation on 25 December 2018, strengthened the connection between the Dibrugarh side and the north bank. The bridge itself is approximately 4.94 km long; a figure for the wider bridge project may also include approach railway lines. [13]
Electrification and additional tracks
Electrification changes the traction infrastructure used by trains. Doubling or adding a third line increases track capacity. These improvements are different from building a new railway into an unconnected area.
NFR has reported end-to-end electric traction up to Dibrugarh and Naharlagun. Such progress should be described by the commissioned section rather than used to assume that every existing and future northeastern route has identical electrification status. [15]
Why railway-length figures need careful reading
- Route kilometres: the length of a route, irrespective of whether it has one or more parallel tracks.
- Track kilometres: the length of individual tracks; this can exceed route kilometres.
- Project length: the scope of a particular new-line, conversion or doubling scheme.
- Zonal total: may include railway lines outside the eight northeastern states.
A state-wise railway-length comparison is meaningful only when every state uses the same reporting date and measurement. Mixing a recent project length with an older state total can produce a misleading picture of railway expansion.
Why Rail Connectivity Matters to Northeast India
Movement of essential goods
Railways provide a means of moving bulk goods such as foodgrains, cement and other construction materials over long distances. The Sairang extension provides a recent example of freight reaching closer to a hill-state market. [3]
Education, healthcare and everyday mobility
Better rail access can widen travel choices for students, workers, patients and families. Its practical value depends on more than the existence of tracks: frequency, fares, station access and reliable onward transport also matter.
Tourism and access to hill destinations
Stations act as gateways to destinations beyond the railway. A traveller may complete the first part of a journey by train and continue by road to a hill town, village or protected area. Rail connectivity should therefore be assessed together with the time and cost of the final road journey.
Regional and strategic connectivity
Additional railway routes can improve the movement of supplies and strengthen connections between border states and the rest of the country. International projects may offer further trade opportunities, but their benefits depend on operating arrangements as well as physical infrastructure.
The wider setting is explained in our article on the international borders and geographical boundaries of Northeast India .
Challenges to Railway Development in Northeast India
Railway development varies sharply between broad river valleys and steep hill terrain. The same straight-line distance can require very different construction work in the two settings.
- Steep terrain: railway gradients require carefully designed alignments, tunnels and bridges.
- Complex geology: weak rock, fault zones and groundwater can complicate tunnel construction.
- Monsoon conditions: heavy rainfall can restrict working seasons and increase slope-management needs.
- Land and access: construction requires land, approach roads, utility relocation and coordination with local communities and authorities.
- Environmental considerations: forest areas, drainage systems and wildlife movement need attention in planning and operation.
- Network bottlenecks: opening a new branch can increase demand on an existing single-line approach.
The Nagaland government’s June 2026 railway review specifically identified difficult geology, landslide-prone terrain, heavy rainfall and groundwater ingress among the challenges affecting the capital-connectivity project. [4]

Frequently Asked Questions
Which railway zone serves Northeast India?
Northeast Frontier Railway is the main zone serving the region. Its headquarters is at Maligaon, Guwahati, and its jurisdiction also includes parts of West Bengal and Bihar.
Do all eight northeastern states have an operational railway?
Seven states have established railway infrastructure. Sikkim’s first link, Sivok–Rangpo, remains under construction in the official records reviewed for this September 2026 guide. Railway access within a state does not necessarily mean access to its capital.
Does Mizoram now have a railway connection near Aizawl?
Yes. The Bairabi–Sairang line opened on 13 September 2025. Sairang is the railway gateway serving the Aizawl area; an onward road journey is needed to reach the city.
Can passengers travel directly to Shillong by train?
A completed railway connection to Shillong was not verified in the sources reviewed. Meghalaya’s established rail access at Mendipathar is in the Garo Hills and should not be confused with the proposed Byrnihat–Shillong route.
Is the Jiribam–Imphal railway line fully open?
No full opening was established in this review. Jiribam–Khongsang is a commissioned section, while the August 2026 project review still described construction on the onward sections toward Imphal.
Does the Dimapur–Kohima project already reach Kohima?
The June 2026 Nagaland government review confirmed the sections through Shokhuvi to Molvom as commissioned. It described work on the remaining sections as ongoing. The project’s Zubza destination serves the wider Kohima area.
Is Rangpo railway station the same as Gangtok railway station?
No. Rangpo and Gangtok are separate places. The Sivok–Rangpo project is intended to bring the railway into Sikkim at Rangpo; it is not a completed railway connection to Gangtok.
Is New Jalpaiguri located in Northeast India?
New Jalpaiguri is in West Bengal, outside the eight northeastern states. It is nevertheless a major railway gateway for journeys toward Sikkim and the Northeast.
Where should travellers check current trains and running status?
Check Indian Railways’ current timetable and NTES running information, and use IRCTC or an authorised booking channel for reservations. Infrastructure maps cannot confirm whether a particular train runs on a particular date.
