DELHI (Metro Rail News): The NCR Transport Corporation (NCRTC), which is executing the Delhi-Meerut (RRTS) corridor connecting Delhi, Ghaziabad and Meerut, has floated tenders for its first underground section proposed between New Ashok Nagar in East Delhi and Sahibabad in Ghaziabad.
The project cost would be ₹30,274 crore and developed with an aimed tp provide high-speed connectivity between Delhi, Ghaziabad and Meerut.
The 82km RRTS corridor will be mostly elevated and only 11.53km will be underground. The first section of 5.8km — between New Ashok Nagar (elevated) in East Delhi and Bharat Electronic Limited in Sahibabad area of Ghaziabad— will be taken up first of 11.53 km.
The Anand Vihar RRTS station will be the only underground station of the 5.8km section. The station will be constructed near the existing Metro station (elevated) and the ISBT Anand Vihar and provide an interchange facility for commuters to switch between different transport systems. like Train, bus, metro and RRTS
Sudhir Kumar Sharma, chief PRO, NCRTC, said that the tender has been floated for the 5.8km underground section and it is on a design-and-build basis. This means that the broad parameters are given by NCRTC while the structural, foundation design, etc., will be done by the selected contractor. The tunnelling for the underground section will be about 6.5 metres in diameter — slightly more than the normal Metro train tunnel diameter, which is of about 5.8 metres,”
The officials said that underground sections have been proposed keeping in mind the profile of an area, the density of population, availability of right of way and presence of buildings.
“There will be two tunnels for dual movement of trains in the first underground section (5.8km). The midsection between the two tunnels will have a passage, in case of a breakdown or the need for rescue operations. The diameter of the RRTS tunnels will be more as these trains are of high speeds. We would require bigger cutters than the normal ones used by tunnel boring machines,” an NCRTC officer said.
The 17km long priority section (elevated) from Sahibabad to Duhai in Ghaziabad is already under construction and will be completed by March 2023. Once the priority stretch is ready, the NCRTC has plans to open the stretch for operations.
The NCRTC has also started the work for engaging a detailed design consultant (DDC) for Sarai Kale Khan and New Ashok Nagar stations, a multimodal integration scheme and a stabling yard in Jungpura.
The NCRTC officials said the second underground stretch, of 5.73km, has been proposed in Meerut. This section will start after Bhrampuri Metro station and trains will cross three underground stations of Meerut Central, Bhaisali and Begumpul to come up on to the elevated section at MES Colony.
The entire 82km corridor is slotted to be ready by March 2025. In all, the corridor will have 24 stations, including two depot stations in Duhai and Modipuram (Meerut).
