Kolkata (Metro Rail News): The Construction work of Victoria Metro station of the Purple Line of Kolkata Metro has been going on smoothly. Joka -Majerhat stretch of this Purple Line has already been operational and efforts are now on to extend it further in order to reach the heart of the city. Construction work of Mominpur (Excl.) to the Esplanade stretch of this Corridor has been going on in that direction. A work order for the construction of this stretch has already been issued to M/s. Larsen & Toubro in last July.
Out of the four stations on this stretch (Khidderpore, Victoria, Park Street and Esplanade) construction work of the underground Victoria station has been taken up by the executing agency Rail Vikas Nigam Limited (RVNL). This station will be 325 meters long and its platform level will be at a depth of 14.7 meters from the surface.
Barricading work of the area required for the construction of this underground station and other preparatory works are now complete. At first, diaphragm walls (D-walls) are being constructed and then the station slabs will be constructed following the Cut and Cover Top-Down Method. Already construction of 115 metres of diaphragm walls has been completed. At Victoria Station, a total of 709 metres of diaphragm walls will be constructed.
Some encroaching trees at the station site were infringing the construction work of this station. It was decided to transplant those trees following all stipulated norms to a nearby area. Hon’ble Calcutta High Court has already dismissed a plea challenging the transplantation of these trees on 20.06.2024. In order to construct this station, already 22 trees have been transplanted to Kamardanga Railway land. This has cleared the infringements towards the construction of this station.
During the construction of the station, special care has also been taken to assess the vibration level generated and also for the nearby Victoria Memorial Hall.
For the tunnelling work of the stretch from the Khidderpore to Park Street stretch of this Corridor, two Tunnel Boring Machines (TBM) will be deployed from the Khidderpore launching shaft. At present, construction of this launching shaft inside the St. Thomas School premises at Khidderpore is in progress.
