Tricity Metro Project: MoHUA Approves Underground Route for Chandigarh Section

The Tricity Metro project linking Chandigarh, Mohali, and Panchkula received a major boost from the centre. The Union Ministry of Housing and Urban Affairs (MoHUA) gave approval for running all metro lines underground in Chandigarh from sectors 1 to 30. This decision aims to preserve the city’s heritage and architectural integrity.

This decision stemmed from the recommendations of the Chandigarh Heritage Conservation Committee’s sub-panel, which emphasised the preservation of the city’s heritage.

As per the report prepared by RITES for the 154-km Metro network across the Tricity, the corridor was originally planned to feature elevated tracks and stations.

The newly sanctioned proposal for Chandigarh’s metro network incorporates roughly 8 kilometres of elevated tracks from a planned 20 kilometres. The decision was made with careful consideration to preserve the city’s aesthetic landscape.

Phase 1 of the Tricity Metro Project will feature 3 corridors that will run through Chandigarh, Mohali, and Panchkula. The corridor passing through Chandigarh’s heritage sectors (1 to 30) is planned to be constructed underground. By situating this segment underground, the project aims to minimise visual disruption and maintain the city’s iconic urban landscape. The work of Phase 1 is likely to commence by 2027.

On the other hand, the other two corridors in Phase 1 of the Tricity Metro Project will feature elevated sections, with some segments also running underground. 

Looking ahead to Phase 2, which focuses on Mohali and Panchkula, the plan primarily includes elevated sections. 

Funding of Tricity Metro Project

The Tricity Metro Project will finance approximately 20% of its funding from each of the states involved, Haryana and Punjab, with an additional 20% contributed by the central government. The remaining 60% of the estimated Rs 10,570 crore project cost will be secured through loans from a lending agency.

Mumbai Metro 3: RDSO Conducts Trials of Rolling Stock on Aqua Line

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.
