The Northeast Frontier Railway (NFR) has commissioned the 6.8-km Rangapani-Bagdogra siding line under its Katihar Division for regular freight operations, opening a key goods movement corridor in the Siliguri region of Darjeeling district, North Bengal. The move, announced on Sunday, 1 November 2026, is expected to significantly boost freight connectivity across the strategically sensitive Chicken's Neck corridor.

Why This Line Matters

The Rangapani-Bagdogra corridor sits at one of India's most critical railway junctions — the narrow Siliguri Corridor, colloquially known as the Chicken's Neck, which links the northeastern states to the rest of the country. Reactivating this line with minimal expenditure makes productive use of existing infrastructure to meet growing freight transportation demands, according to NFR's Chief Public Relations Officer (CPRO) Kapinjal Kishore Sharma.

Notably, the line had been long disused before this commissioning, making its revival a cost-effective infrastructure win rather than a fresh capital outlay.

Key Operational Benefit: No More Reversals at Siliguri Junction

One of the most significant operational gains from this development is the elimination of mandatory reversals at Siliguri Junction (SGUJ). Previously, trains coming from East Central Railway (ECR) and entering NFR at Forbesganj were required to reverse at Siliguri Junction before proceeding further — a time-consuming and resource-intensive manoeuvre.

With the new arrangement, this reversal is no longer needed. This translates into substantial energy savings, reduced detention of rolling stock, and lower deployment of crew and shunting staff, according to Sharma.

Freight Capacity and Traffic Gains

The operational shift will enable NFR to receive at least 10 trains per day from ECR at Forbesganj for onward movement to destinations beyond Barsoi. This enhancement in throughput is expected to improve freight handling capacity, accelerate goods movement, and allow better utilisation of rolling stock across the division.

The additional route also offers greater operational flexibility, giving railway planners more options during maintenance windows or disruptions on existing corridors.

Impact on Trade and Supply Chains

For traders, businesses and consumers in the region, the development is expected to support more reliable transportation of goods and strengthen local supply chains, Sharma said. The initiative also creates scope for NFR to handle additional freight traffic and generate revenue through better utilisation of an existing asset.

The conversion was carried out under the guidance of NFR General Manager Chetan Kumar Shrivastava, with coordinated efforts from the Katihar Division and concerned departments. The NFR, headquartered at Maligaon near Guwahati, operates across the northeastern states as well as in seven districts of West Bengal and five districts of north Bihar.

With freight demand on the northeastern rail network continuing to rise, the recommissioning of dormant infrastructure like the Rangapani-Bagdogra line signals a broader NFR push to optimise existing assets before committing to fresh capital projects.
