🔧 Boosting Connectivity: Odisha’s Longest Rail Tunnel Now Operational
In a historic step forward for Odisha’s transportation infrastructure, Tunnel No.-4 (T4) on the Khordha-Bolangir railway line was officially opened on Wednesday, marking the completion of the longest railway tunnel in the state. Stretching over an impressive 4.18 kilometres, the tunnel is situated in Boudh district and stands as a landmark achievement for the East Coast Railway (ECoR) zone.
This major infrastructure milestone is poised to enhance rail connectivity, facilitate regional development, and reduce travel time for commuters and freight alike in Odisha’s western and central districts.
🛤️ A Major Engineering Feat: Tunnel No.-4 (T4)
Tunnel T4 is the final segment of a group of four tunnels constructed along the Khordha-Bolangir route. While tracks were already laid in the previous three tunnels, T4’s completion signifies a turning point, both in terms of engineering complexity and project execution.
The tunnel’s construction was successfully executed without any disruptions or safety incidents, showcasing the technical expertise and coordinated efforts of the ECoR workforce.

🗨️ Official Statements: Pride for East Coast Railway
Parmeshwar Funkwal, General Manager of East Coast Railway (ECoR), remarked:
“It is a historic moment. Because this is not only Odisha’s longest tunnel but also the longest tunnel of East Coast Railway (ECoR). I am immensely happy that I witnessed the historic moment.”
He further credited the entire ECoR team for their dedication and perseverance:
“This is a result of the relentless efforts of our entire team. It is an achievement for all. This is a milestone for the Khordha-Bolangir railway line.”
🔍 Background: Momentum from T3 Breakthrough in January 2025
Earlier this year, on January 13, 2025, the Khordha-Bolangir rail project celebrated another major success with the breakthrough of Tunnel T3, located between Buguda and Banigochha in Nayagarh district.
- Tunnel T3 measures 2.62 kilometres in length and features a 2-degree curve.
- Excavation followed the New Austrian Tunneling Method (NATM), ensuring stability and safety during complex terrain boring.
- The successful daylighting of Tunnel T3 symbolised steady progress on this high-priority public infrastructure project.
🛤️ Strategic Importance of the Khordha-Bolangir Rail Line
The Khordha-Bolangir railway project is a crucial connectivity corridor aimed at integrating western Odisha with the coastal belt. It is expected to:
- Boost trade, tourism, and mobility between backward and developed regions,
- Promote inclusive development in Kandhamal, Nayagarh, Boudh, and Bolangir districts,
- Alleviate logistics bottlenecks for agricultural and forest produce.
