The Dedicated Freight Corridor Corporation (DFCC) completed the construction of the world’s first electrified rail tunnel that is fit to run double-stack containers through Aravalis in Sohna.

The one-km tunnel is located on the Rewari-Dadri section of the Western Dedicated Freight Corridor (DFC). The tunnel connects the Mewat and Gurgaon district of Haryana. The tunnel has provision for double line electrified track for double stacks train movement. Geologically this tunnel is safe and stable as it is caved through 250 to 500 million-year-old proterozoic rocks that have a high bearing capacity.

Important Info :

The Western DFC and most parts of the Eastern DFC are slated for completion in June 2022, which will make the movement of freight trains seamless.

The D-shaped tunnel has a cross-sectional area of 150 square metres to accommodate double line with higher OHE (Over Head Equipment) to enable double-stack container movement on WDFC. Cross-sectional area-wise, it is one of the biggest Railway tunnels in India. One end of the tunnel is near Rewari while the other end of the tunnel is at Dadri. The Dimension of the tunnel is 14.5 meters and 10.5 metres height in straight portion and 15 metres wide and 12.5 metre height to provide extra clearance while negotiating the curve.
