At the beginning of April NCRTC achieved its first tunnel breakthrough for the Delhi section of the Delhi - Ghaziabad - Meerut RRTS corridor. The TBM Sudarshan 4.1 made the breakthrough from the tunnel retrieval shaft constructed at Khichdipur, Delhi.  

The first TBM of the Delhi section, Sudarshan 4.1, was lowered at the Anand Vihar launching shaft in January 2022 for the construction of RRTS tunnels between Anand Vihar and Khichdipur. This RRTS tunnel is the longest tunnel in Delhi made by any TBM and is about 3 km long.  Click here and in/88 for the tunnelbuilder archive and also visit https://ncrtc.in. 16/23.
