The tunneling work for the 5.5-km stretch from New Ashok Nagar in Delhi to Anand Vihar is already underway, while NCRTC has also started work to link Anand Vihar and Vaishali in Ghaziabad. The finished tunnels on both sides will be 6.5 metres in width and will facilitate the movement of RRTS trains, which have a high design speed of 180kmph. The entire stretch of 5.5- km will have two up and down lines for trains. The underground section will have safety features such as cross passages, side walkways for passengers and ventilation shafts.
