National Capital Region Transport Corporation (NCRTC) has begun the tunnelling work at Anand Vihar for the first regional rail corridor of India from Delhi to Ghaziabad and Meerut. For this, a 90 m long Tunnel Boring Machine (TBM) has started building a tunnel for the first Regional Rapid Transit System (RRTS) corridor of India from Anand Vihar towards the New Ashok Nagar side. The TBM includes a front shield, middle shield, tail shield, cutter head, erector, screw conveyer, and multiple other parts that help in boring the tunnels effectively. Tunnel rings are also being constructed with the help of tunnel segments by the TBM. Usually, seven tunnel segments are used to construct a tunnel ring. Tunnel segments for this section are being built at the Casting yard of the National Capital Region Transport Corporation (NCRTC) with preciseness and quality control. The RRTS tunnels are bigger compared to the other Metro systems in the country. It is due to the larger rolling stock with a higher design speed of 180 Km per hour RRTS trains. This specific TBM would make nearly 3 km of the tunnel from Anand Vihar towards the New Ashok Nagar side. Four TBMs would be introduced from the Anand Vihar station.Two for a drive from Anand Vihar to the New Ashok Nagar side and the remaining two for a drive from Anand Vihar towards Sahibabad side. For the to and fro movement of the trains, the underground stretches of RRTS would feature twin-separate tunnels. Various safety measures are being done to safeguard the safety of travellers. Emergency exits are provided for commuters' protection in case of an emergency, and every 250 metres, a cross-passage would be located. Some of the reasons for project execution are decongestion of the National Capital, decreasing automobile traffic and air pollution, and balanced regional growth. The construction work on the whole 82 Km long Delhi-Ghaziabad Meerut RRTS corridor is moving rapidly. It will have 25 stations, including two depots and one stabling yard.
