Mumba (Metro Rail News): On June 25, 2024, the Mumbai Metropolitan Region Development Authority (MMRDA) opened technical bids for Package CA-207. This package involves the construction of the Dongri Depot on the Red Line of the Mumbai Metro. Three firms have submitted proposals to carry out the work for this package.

The Dongri Depot and Workshop, under Package CA-207, is planned to be built on 41.36 hectares of land in northwest Mumbai. This facility will be designed to accommodate and maintain BEML trains serving the entire Red Line, which includes Line-9, Line-7, and Line-7A. These lines connect Dongri, Mira Bhayandar, Dahisar East, Gundavali, and CSIA Terminal 2.

Additionally, the Dongri Depot will feature an Operations Control Centre (OCC), a 690-meter-long test track with platforms, a stabling shed (SBL), a workshop shed (WSL), an inspection shed (IBL), a receiving substation (RSS), and two auxiliary substations (ASS).

Bidding Process

In February 2024, MMRDA called for bids for the package CA-207, estimating the project at Rs. 626.69 crore. The project has a completion timeline of 52 months.

Firms

Three firms who have submitted the proposal to construct Package CA-207 are the following:

KPC Projects Ltd.
Ritwik Projects Pvt. Ltd
NCC Ltd.

Scope of work

The work under Package CA-207 includes the development of the depot land and the construction of essential infrastructure for the Depot at Dongri, part of Metro Line-9 of the Mumbai Metro Rail Project by MMRDA. This includes:

Stabling Yard
Operations Control Centre
Depot Control Centre
Administrative Building
Maintenance and Inspection Buildings
Auxiliary Substation
Roads
Underground Utility Ducts
Drainage System
Rainwater Harvesting Facilities

Additionally, the project involves architectural finishing, plumbing, and pre-engineered building (PEB) works.

The bids submitted by the three firms will now undergo a comprehensive technical evaluation process which can take a few months to complete. Once this evaluation is done, MMRDA will proceed to open the financial bids of the technically qualified bidders to identify the L1 (Lowest bidder) for Package CA-207.

A 4.9 km extension of Line 9 will provide access to the Dongri Depot. This extension originating from Subhash Chandra Bose Ground Station will run along Uttan Road.

Mumbai (Metro Rail News): The work is advancing swiftly on the Aqua Line (Line 3) of the Mumbai Metro. In a recent development, the Research Design and Standards Organisation (RDSO) has wrapped up the testing phase for the rolling stock designed for the Mumbai Metro’s Line 3, which runs underground between Aarey and Seepz via BKC. Currently, trials are underway in Phase 1, which extends from Aarey to Bandra-Kurla Complex (BKC).

On 24 June 2024, an update on the official X account of the Mumbai Metro 3 project announced the completion of oscillation trials for the Metro rakes. The Research Design and Standards Organisation (RDSO) will now submit the trial report to the Railway Board and the Commissioner of Metro Rail Safety.

Meanwhile, other electrical system tests and integrated testing of the rolling stock with signalling are ongoing. Once these tests are completed, the Commissioner of Metro Rail Safety (CMRS) will be called for the final inspection before commencing the public operations in Phase 1.

Commencing on June 8, the trials were executed at a maximum speed of 95 km/h using both empty and loaded rakes. These oscillation trials are essential as they assess how well the train performs dynamically and maintains stability at different speeds.

A thorough assessment of the dynamic stability of rolling stock, especially at high speeds and on curves, is crucial to minimise the risk of derailments. Additionally, testing includes a detailed analysis of how the rolling stock interacts with the track, specifically evaluating the forces applied on the rails. Through these tests, RDSO ensures compliance with safety standards to prevent accidents and ensure passenger safety.

Mumbai Metro Line 3

Mumbai Metro’s Aqua Line (Line-3), spans 33.5 kilometres and serves as a crucial north-south corridor, designed to streamline connectivity throughout Mumbai. It will link six commercial suburbs, 30 office areas, 12 educational institutions, 11 major hospitals, and 10 transport hubs, including both of Mumbai’s airports. Once operational, this corridor is expected to alleviate congestion on roads. The operations for Phase I of the Mumbai Metro Line 3 are anticipated to commence by the end of 2024.

Bullet Train Project's 3rd OWG Bridge — default

Gujarat (Metro Rail News): On 23 June 2024, National High-Speed Rail Corporation Limited (NHSRCL) successfully launched a 130-meter-long steel bridge over the Delhi-Mumbai national expressway. The bridge in Vadodara near Gujarat is part of the Mumbai-Ahmedabad Bullet Train project.

This is the third successful completion of a steel bridge out of 28 steel bridges for the MAHSR corridor. The launch of the first and second steel bridges took place across National Highway 53, in Surat and over the Vadodara – Ahmedabad main line of Indian Railways, in Gujarat respectively.

The launch was completed within 24 hours, and multiple rollers and hydraulic jacks with intermittent breaks to allow vehicular traffic to pass. The bridge weighs 3000 MT with a height of 18 meters and a width of 14.9 meters. It was manufactured in Wardha, Maharashtra. It is expected to be the longest of any other national highway in the country.

The bridge was assembled at a 15-m height from the ground on temporary trestles, and it was pulled with the automatic mechanism of two semi-automatic jacks, each capable of 250 tons. The bridge fabrication utilised approximately 124,246 Nos. of Tor-Shear Type High Strength (TTHS) bolts designed for a 100-year lifespan, with C5 system painting and metallic spherical bearings.

In August 2021, NHSRCL awarded M G Contractors with a bridge package P-1 (C) of Rs. 261.24 crore. P1-C’s scope involves constructing one press trusted concrete (PSC) and four steel truss bridges within 87.569 km package C6, which is under construction by Larson & Toubro.

In October 2023, M G Contractors placed the first open web girder (OWG) of the entire project on Package P-1(B) at MAHSR’s chainage 254.585 across NH-53 near Surat. In April 2024, the first OWG for Package P1(C) was placed over Indian Railways’ mainline track between Kanjari Boriyavi and Uttarsanda stations.

The utmost safety standards are being practised during the project’s execution. Under the ‘Make in India’ initiative, India is making increased use of its technical and material resources, and the major example is the steel bridge for the Bullet Train project.

India boasts the capacity to construct steel bridges for heavy haul and semi-high-speed trains which can operate at 160kmph. Now India is utilising the same expertise to construct steel girders for the MAHSR corridor which is designed to accommodate high-speed trains running at the top speed of 320 kmph.
