Electrified rail tunnel for double stack containers 

2020: A world first

1km tunnel built through Aravalis for freight trains, July 25, 2020: The Times of India

The DFCC completed construction of the world's first electrified rail tunnel that is fit to run double stack containers through Aravalis in Sohna. The work on this one-km tunnel on Western Dedicated Freight Corridor was completed in less than a year despite the Covid pandemic.

The tunnel is located on the Rewari-Dadri section of the corridor. The tunnel has provision for double line electrified track for double stacks train movement, the Dedicated Freight Corridor Corporation (DFCC) said.

It said geologically this tunnel is safe and stable as it is caved through 250 to 500 million year old proterozoic rocks which have high bearing capacity. Double stack containers and 25 tonne axle load freight trains will run through this tunnel at a speed of 100 kmph.

The tunnel connects Mewat and Gurgaon district of Haryana and negotiates a steep gradient on the uphill and downhill slope of the Aravalli range. 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.
