Kolkata (Metro Rail News): Construction work on the Purple Line beyond Majerhat station has got a major boost in recent times. The Purple Line of Kolkata Metro, which stretches from Joka to Esplanade, is now operational from Joka to Majerhat. Efforts have been made to extend it further as per the plan and reach the heart of the city to connect it with the Blue Line as well as the Green Line. In order to achieve this, 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.

Mominpur-Esplanade Section

After Mominpur, this stretch will go underground, and four stations, namely, Khidderpore, Victoria, Park Street and Esplanade, will be underground stations. All these stations will be modern, state-of-the-art stations replete with all passenger amenities. Executing agency Rail Vikas Nigam Limited (RVNL) is bringing two Tunnel Boring Machines (TBM) to burrow the tunnels for this stretch from Germany. These TBMs are expected to arrive in Kolkata in January 2025 and, after assembling, will begin their tunnelling work from March 2025.

Prior to that, the preparatory work to construct the launching shaft has been going on. The construction of the D-Wall of this launching shaft started on 27.06.2024 at St. Thomas School premises at Khidderpore. The length of this D-Wall will be 65 metres and this construction is expected to be over within two months. This is a major boost for this project after overcoming a lot of administrative and legal problems.

Apart from that, the casting work of the tunnel segments has also been started at the casting yard at Sarkarpool in Maheshtala. The width of each segment which will be used in the tunnels is 1.40 metres. Six such segments will be required to form an one complete ring with an inner diameter of 5.80 metres and a width of 1.40 metres. All these pre-cast segments will be brought to the site before the tunnelling work begins. The TBM machines, immediately after boring the tunnels, will fix the lining with these pre-cast segments under the ground to give it a final shape.

New Delhi (Metro Rail News): On July 1, the Delhi Metro Rail Corporation (DMRC) announced that as part of Phase 4, the Tughlakabad Metro Station will be developed as an interchange station between the Golden Line (Tughlakabad-Aerocity) and the Violet Line (Kashmere Gate-Raja Nahar Singh). This development will facilitate a smooth transition for commuters travelling on both lines, enhancing connectivity and easing travel for passengers.

Tughlakabad Station’s features

As per DMRC, the existing Tughlakabad Metro Station is being elevated. Additionally, plans are underway to construct a new underground station. These two stations will be connected by a 45-metre-long subway to ensure seamless integration and transitions for commuters between the elevated and underground sections.

The design of the new station incorporates a four-level structure, including an underground floor that will serve as a parking zone with a capacity to accommodate 250 vehicles. Commuters from both the Golden and Violet Lines will have direct access to this floor via lifts, stairs, and escalators, enhancing convenience and accessibility at the station.

Tughlakabad Metro Station will be the first interchange facility in the Delhi Metro network to feature underground parking.

Currently, to access the domestic and international airport terminals, commuters on the Violet Line have to go to the Central Secretariat station and then transfer to the Airport Express Line.

The opening of the new line will save time for passengers from Faridabad in Haryana. They can disembark at the interchange station and proceed directly to the airport.

Delhi Metro Phase 4: All Three Priority Corridors likely to be Operational by 2026

Staff Reporter

02/07/2024

New Delhi (Metro Rail News): The Delhi Metro Rail Corporation (DMRC) is progressing rapidly with its Phase 4 expansion work with the target of opening all three priority corridors comprising 65 kilometres of new lines by 2026. Though work on the fourth phase of expansion started in December 2019, immediately after the finalization of tenders, progress of work was significantly impacted from 2020 to 2022 for almost three years due to the Covid pandemic and delays in getting tree-cutting permissions.

DMRC has been working continuously on the Phase 4 project practically since the last one and a half – two years only, which gives the organisation just about four years’ time to complete the entire work by the year 2026.

Progress in Delhi Metro’s Phase IV

At present, over 50 percent progress has already been achieved on all three corridors. On the Majlis Park – Maujpur section, about 80 percent of civil work has already been completed. Tunneling works are in progress on various stretches on the Aerocity – Tughlakabad (Golden Line) and the Janakpuri West – RK Ashram Marg (Magenta Line) corridors.

Despite the adverse situation of COVID-19 and the delay in various permissions, the Phase 4 section from Janakpuri West to Krishna Park Extension is now almost complete and is likely to be opened by August 2024. The Majlis Park – Maujpur corridor is also likely to be opened during the next year. The rest of the sections of the priority corridors are expected to be opened in a phased manner by 2026. However, certain permissions for tree cutting and the acquisition of land pockets at isolated locations are still awaiting approval.

The project is being monitored at various levels on a day-to-day basis. Site visits are also taken up at the highest level to expedite the work. Tree-cutting permissions are being pursued at appropriate levels.

The Addition of 2 New Corridors

Two more corridors under Phase 4, Inderlok – Indraprastha and Saket G Block – Lajpat Nagar have also received approval recently. DMRC at present is processing for statutory clearances including land acquisition from the concerned authorities. Forest clearances and tree-cutting permissions are also being taken up at the appropriate levels. Further processes regarding the planning and tendering for civil works are in progress.

Bangalore Metro’s TBM Tunga Achieves Breakthrough at K G Halli Station — TBM Tunga

Bangalore (Metro Rail News): On 27 June, Bangalore Metro’s Pink Line encountered a major setback when authorities halted the operations of Tunnel Boring Machine (TBM) Tunga due to the appearance of a sinkhole on the road in KG Halli, located in northeastern Bengaluru.

As per a senior BMRCL official, the sinkhole measures roughly between 2.5 to 3 meters in width and 3 meters in depth and is likely to have appeared due to either an air pocket or loose soil conditions.

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.
