Chennai Metro | No mobile connectivity for Chennai Metro’s underground stretch

Chennai: When Chennai Metro Rail Limited (CMRL) has flagged of the Thirumangalam and Nehru Park metro rail, the officials had promised to offer mobile connectivity. This service was to be made available for the underground stretch, but a year has passed by and Chennai Metro commuters are still waiting for the promise to be fulfilled.

There is still no mobile connectivity at the underground stretch. CMRL officials had assured that they have installed mobile transmitters and connectivity at underground metro stations will be established by end by February. But there is no glimmer of hope as May is about to end and there is no sign of the services to start soon.

Commissioner of Metro Railway Safety (CMRS) completed safety inspection of Chennai Metro Underground Section.

Commuters have to suffer as they are not able to use their mobile phones when travelling through underground stretch using Chennai Metro. CMRL officials have been assuring that they are conducting test runs to see how the installed system is working. They have been promising that the services will be made available soon. But the promise is yet to light of the day.

The delay can also be attributed to the fact that CMRL is currently focusing on starting operations at two stretches. These include the Saidapet to AG-DMS and Nehru Park to Chennai Central Chennai Metro. Owing to work going on these two stretches, officials are unable to devote time for starting mobile connective at old as well as new underground stations.

Many commuters who have been waiting to take the Chennai Central to in Nanganallur through the Chennai Metro Rail are avoiding it. Office goers want mobile connectivity as it will not disrupt their work in case they are travelling via the underground route. People have complained that they are unable to make calls when travelling on the route and have requested the authorities to find a solution at the earliest.

Mumbai Metro | MMRC completes 15% construction work in Colaba-Bandra-SEEPZ corridor

Mumbai: The Mumbai Metro Rail Corporation (MMRC) has completed approximately 15-16 percent of the civil construction for 33.5km of the 33-tunnel underground corridor. Work on the longest tunnel corridor in the country began in November 2016.

The first tunnel boring machine (TBM), called Krishna 1, started tunneling from the Nayanagar near Dharavi on November 9 and has now drilled 120 meters. Meanwhile, six other TBMs, lowered in different parts of the city, have combined 394 meter tunnels so far. 17 TBMs will operate 15 to 25 meters below ground to drill 51 km of tunnels.

Mumbai Metro-3 Tunneling Work

Like Krishna, the TBMs in each of the seven packages are named after a river in Maharashtra: Surya, Vaitarna, Tanasa, Godavari, Tapi and Wainganga. Each package has at least two and no more than three TBM in operation.

“It’s better to refer to the machines with names with numbers because they are more identifiable. It’s a more personal connection with machines when they have a name. By naming just searched for names that were easy to remember and pronounced because they all relate to those with these names, “says SK Gupta, Director (Project), MMRC.

The Colaba-Bandra connection SEEPZ is likely to be completed in December 2021. The first phase of Aarey Milk Colony connecting the airport will be operational in March 2021, while the second phase of Cuffe Parade will be ready for December brokers.

According to a MMRC official, “The work involves workforce of about 7,600, including skilled and unskilled workers. “This adds staff to General Consultants (GC), MMRC staff, managers and engineers from civilian contractors and several suppliers working on the project.”

Works at all 26 subway stations and one in the rating station has begun and 53 percent of stacking activity has been completed with 16,597 batteries.

About 1500 people affected by projects (PAP) have been rehabilitated to build the corridor at a cost of 23,136 crore.

At the same time two elevated metro corridors are under construction in the suburbs: Dahisar West DN Nagar Metro Dahisar 2A and East Andheri East Metro 7. Even the construction of the two runners began in November 2016 Metro 2A completed around 35 percent of the building and the subway 7 has stopped about 45 percent.

The project is being carried out by the Delhi Metro Rail Corporation (DMRC). For the construction of the 18.5-km Metro 2A, 400 out of 957 piers have been erected and out of 1430 U-girders 215 have been erected. Meanwhile, 64 per cent of the piling activity has been completed.

5-km Metro 7 corridor, 227 of 709 piers have been erected and 198 of 1184 U-girders have been erected, apart from 73 per cent of the piling activity being completed. Here three stations are in advanced stage of construction in Aarey Colony, Mahanand and Magathane.
