The world's first electrified double-stack container train tunnel will house two broad gauge lines

New Delhi: The caving work for electric line of Indian Railways has just been completed at Western Dedicated Freight Corridor’s (DFC) 1-km-long tunnel through the Aravalli mountain range in Haryana.

This project is the first-ever electrified railway tunnel in the world that will be able to run double-stack container trains. The construction of the tunnel was started in 2019 and the last blasting on the end of the tunnel was completed on July 24, 2020. The tunnel will allow 25 ton axle load freight containers at a speed of 100 kilometres per hour.

The newly constructed tunnel now connects the district of Mewat and Gurugram and has a steep gradient consisting of uphill and downhill slope in the Aravalli range.

To allow the movement of double-stack container freight trains, the cross-sectional area of the tunnel is at 150 metres and is one of the biggest cross-sectional railway tunnels in India.

In the Eastern and Western DFC on Aravalli range, there are a total of six tunnels. The world’s first electrified train tunnel will house two broad gauge lines and the work has been completed in less then a year’s time.
