New Delhi, (Metro Rail News): More than one-third piers of the elevated stretch of India’s first regional rail have been completed, which is getting built at a rapid speed to connect Delhi to the urban nodes of Ghaziabad, Modi Nagar, and Meerut. In this 82 km long RRTS corridor, a total of 70 km area is elevated; out of which piers have been erected in 24 km stretch so far.
On this corridor, a 12 km portion is to be constructed underground, of which about 4 km is in Delhi, and 8 km is in Uttar Pradesh. For the construction of the underground part of Delhi, activities have picked up the pace at Anand Vihar. Currently, a launching shaft is being constructed from where the tunnel boring machines will be launched to bore RRTS tunnels. It is to be noted that the RRTS tunnels are slightly larger, and their diameter is 6.5 meters.
In Meerut also underground construction work has already started with the construction of the Bhaisali underground station. Under which the construction of D wall for the station has started, and a total of 121 fencing panels are being concreted by lowering the cages underground.
So far, NCRTC has erected more than 800 piers under the construction work of the elevated part as well as 8 km of the RRTS viaduct. In this, most of the viaduct has been constructed in the priority section of the corridor between Sahibabad to Duhai. Track laying has also started in this section. The construction work is progressing with the finalization of the design and architecture of the RRTS station in the priority section of 17 km between Sahibabad and Duhai and the construction work at all stations is progressing well.
The train design is also in the final stage and is manufactured completely in India at Alstom’s (Bombardier) Savli plant in Gujarat. The trains will have a design speed capability of 180 Kmph. The construction of the train’s stabilizing and inspection line and control center is at a fast pace at Duhai depot for operations and maintenance. The track laying process has been initiated at Duhai. Currently, the work of OHE (Over Head Equipment) for the stabling line is going on at Duhai Depot.
Even after the work was affected in many sections due to Covid-19, presently, construction is going on with massive mobilization of launching gantries (तारिणी) on the entire 82 km corridor. Deployment of 16 gantries for any rail-based urban infrastructure project is rare and the first of its kind. Four more gantries are being launched shortly taking this number to 20. The priority section of 17 km between Sahibabad to Duhai is targeted to be commissioned by 2023 and the full corridor by 2025.
The construction activities are being carried out while following COVID-19 appropriate behaviour at construction sites, with due safety protocols in compliance to COVID SOPs.
