In a significant development for India’s northeastern and Himalayan regions, the Ministry of Railways has sanctioned ₹8.48 crore for the Final Location Survey (FLS) of the proposed Melli-Dentam railway line in Sikkim. This move represents a crucial step forward in extending rail connectivity to the southern and western parts of Sikkim, a border state of strategic importance that has long faced challenges in terms of transport infrastructure.
The allocation for the FLS was officially communicated to the Northeast Frontier Railway through a formal letter issued on October 24, 2025, signaling the government’s commitment to fast-tracking the preliminary stages of the project. The FLS is a pivotal component of the railway project’s planning process, as it involves the detailed mapping and feasibility assessment of the proposed route, taking into consideration terrain, geological challenges, and environmental factors.
The Melli-Dentam railway line is intended to enhance access to remote areas of Sikkim, fostering economic development, improving mobility for residents, and creating opportunities for tourism in the picturesque yet geographically challenging region. Officials note that once completed, the railway line would significantly reduce travel time between Sikkim’s southern towns and its western districts, facilitating smoother movement of goods and passengers while also enhancing national security infrastructure along the sensitive border areas.
Political Push and Advocacy for the Project
The recent funding decision comes after sustained advocacy by Sikkim’s political representatives. Notably, Indra Hang Subba, Sikkim’s Lok Sabha Member of Parliament, met with Union Railway Minister Ashwini Vaishnaw on July 25, 2025, urging expeditious action on the Melli-Dentam project.
During the meeting, Subba emphasized the importance of completing the Final Location Survey, preparing and approving the Detailed Project Report (DPR), and initiating early execution of the railway line. The MP highlighted the multiple benefits of the project, including improved accessibility to remote towns, promotion of tourism in scenic and strategic regions, and strengthened national security infrastructure along the sensitive India-Sikkim border. Subba’s proactive approach underscored the political significance of the railway project, aligning local development priorities with national objectives.
Officials from the Railway Ministry reportedly assured the MP that efforts were underway to expedite survey and approval processes, citing technical and logistical challenges typical of rail projects in hilly and mountainous terrain. The allocation of ₹8.48 crore for the FLS represents a tangible outcome of these discussions, clearing a major procedural hurdle and paving the way for subsequent phases of the project.
Strategic Importance of Melli-Dentam Railway Line
Sikkim, a mountainous state bordering China, Nepal, and Bhutan, has historically faced infrastructural constraints that have hindered both economic growth and emergency preparedness. The proposed Melli-Dentam railway line is expected to strengthen connectivity not only within the state but also between Sikkim and neighboring regions of West Bengal and the Northeast.
Experts point out that railways in Sikkim are particularly valuable for national security purposes, as they allow for faster troop movements and logistical support in border areas. In addition, improved rail connectivity is expected to boost tourism in Sikkim’s southern and western regions, allowing travelers easier access to scenic destinations, hill stations, and cultural sites. Economic activity, including trade and local commerce, is anticipated to rise once the railway line becomes operational, benefiting both residents and businesses in the region.
Parallel Development: Dehradun-Tanakpur Express Frequency Increased
In parallel with the Sikkim railway project, the Ministry of Railways has also approved an increase in the frequency of the Dehradun-Tanakpur Weekly Express (Train No. 15019/15020), reflecting a broader focus on improving connectivity in hilly and remote regions of northern India.
In a letter addressed to Uttarakhand Chief Minister Pushkar Singh Dhami, Railway Minister Ashwini Vaishnawannounced that the train would now operate three times a week, up from its previous weekly schedule. Chief Minister Dhami hailed the decision as a “significant public-welfare-oriented gift” for the people of Uttarakhand, noting that the increased frequency would allow travelers between Dehradun and the Kumaon region to benefit from more regular and convenient rail connectivity.
According to the Chief Minister, the enhanced train schedule is expected to bolster tourism between the Garhwal and Kumaon regions, stimulating economic and social activity in Uttarakhand. The move is anticipated to help local businesses, facilitate trade, and improve mobility for residents, while also providing additional options for tourists seeking to explore the state’s scenic landscapes and cultural landmarks.
Government’s Support and National Perspective
The approval of both the Melli-Dentam railway FLS and the increased frequency of the Dehradun-Tanakpur Express reflects the Central Government’s sustained focus on improving transportation infrastructure in strategic and remote regions of India.
Chief Minister Dhami expressed gratitude to Railway Minister Ashwini Vaishnaw, highlighting that under the guidance of Prime Minister Narendra Modi, the government has consistently supported regional development initiatives. Dhami noted that improved rail infrastructure is integral to Uttarakhand’s socio-economic growth, tourism expansion, and connectivity with other states.
From a national perspective, investments in rail connectivity in Sikkim and Uttarakhand serve multiple objectives: they enhance accessibility to remote areas, contribute to regional economic development, promote tourism, and strengthen logistical readiness in border regions. Officials emphasize that railway expansion in hilly and mountainous terrain, though technically challenging, is critical for inclusive growth and strategic preparedness.
Next Steps for the Melli-Dentam Project
With the ₹8.48 crore allocation in place, the Northeast Frontier Railway is expected to commence the Final Location Survey promptly. The FLS will map out the precise alignment of the proposed railway, considering factors such as slope stability, tunnel feasibility, bridge construction requirements, and environmental safeguards.
Following the completion of the FLS, the Detailed Project Report (DPR) will be prepared, outlining cost estimates, technical specifications, environmental impact assessments, and timelines for construction. Once approved by the Ministry of Railways, the project will move to the execution phase, which involves detailed engineering work, land acquisition, and commencement of civil construction activities.
Officials indicate that given the terrain and climatic conditions of Sikkim, the project may face challenges such as landslides, heavy rainfall, and difficult soil conditions. However, modern engineering techniques and careful project planning are expected to mitigate these risks, ensuring timely completion of the railway line.
Implications for Residents and Businesses
For residents of Sikkim, the railway project promises to reduce travel time significantly, provide an alternative to road transport, and improve access to healthcare, education, and markets. Businesses, particularly those involved in tourism, trade, and local handicrafts, stand to benefit from increased passenger and freight movement.
The FLS allocation also signals the government’s commitment to long-term regional planning. By securing survey funding and expediting initial approvals, authorities aim to ensure that the Melli-Dentam railway line contributes to sustainable development while integrating with broader national connectivity and defense strategies.
Conclusion
The sanctioning of ₹8.48 crore for the Final Location Survey of the Melli-Dentam railway line is a milestone in India’s efforts to enhance connectivity in remote and strategically important areas. Coupled with improvements in the Dehradun-Tanakpur Express, these initiatives reflect a broader push to strengthen infrastructure in northern and northeastern regions.
For Sikkim, the railway line promises better accessibility, economic opportunities, and tourism potential, while for Uttarakhand, the enhanced train frequency supports mobility, commerce, and regional development.
