This record work of the tunnel has been completed in less than one year. Work on this site started in 2019.

Highest OHE for Easy Traffic
Geologically, the tunnel is safe and stable as it passes through 2500–500 million years old Proterozoic rocks, mainly quartzite, schist and slates of the Alwar / Ajabgarh clusters of Delhi Supergroup Rocks, which have high carrying capacity. Through this tunnel, freight trains with double stack container and 25 tonne axle load will pass at a speed of 100 km per hour.

The tunnel connects Mewat and Gurugram districts of Haryana and crosses a strong slope on the sloping and flat slopes of the Aravalli Range. This D-shaped tunnel has a 150-square-meter hybrid sectional area to facilitate double line with the highest OHE (over head equipment) for easy movement of double stack containers over WDFC.
