East Coast Railway Achieves Record Tunnelling Milestone in Eastern Ghats

The East Coast Railway has achieved a major milestone in infrastructure development by successfully breaking through five tunnels during the financial year 2025–26 across the challenging terrain of the Eastern Ghats.

Breakthrough in Challenging Terrain

The latest success came with the breakthrough of Tunnel No. 30 (1,043 metres) in the Sikarpai–Keutguda section of the Koraput–Singapur Road doubling project on April 14, 2026.

Officials said the tunnel was constructed on a difficult 5-degree curve and excavated simultaneously from both ends, achieving 100% alignment accuracy—highlighting advanced engineering precision and execution in complex geological conditions.

Major Progress in Key Railway Projects

Significant progress was also recorded in the strategically important Khurda Road–Balangir new line project. Tunnel T-4 (4,185 metres), the longest on the route, along with Tunnel T-2 (1,775 metres), were successfully broken through, contributing nearly 6 kilometres of tunnelling work.

Earlier, Tunnel T-5 and T-6 (250 metres each) were completed in July 2025, followed by Tunnel T-7 (1,975 metres) in November 2025, marking steady advancement in project execution.

Over 7 Kilometres of Tunnelling Achieved

In total, 7,051 metres of tunnels were broken through during the year, with 2,475 metres fully completed, including lining and associated works. Additional progress was made in doubling sections such as Koraput–Rayagada and Koraput–Singapur Road corridors.

Boost to Connectivity and Regional Growth

Officials stated that these achievements will significantly enhance rail connectivity between coastal and western Odisha. The projects are expected to improve capacity for both freight and passenger movement while connecting remote and tribal regions to mainstream economic activities.

Overcoming Natural Barriers

The milestone reflects the focused and mission-driven approach of East Coast Railway in overcoming difficult terrain and geological challenges. The development is set to play a key role in strengthening transportation infrastructure and supporting economic growth across the state.
