Kolkata, Communications-Based mostly Practice Management signalling work for the whole Howrah Maidan to Sector V stretch of Kolkata Metro’s East-West Metro started on Sunday, marking a historic step towards connecting Howrah with Sealdah, two of Jap Railway’s busiest stations.
East-West Metro CBTC signalling work begins, paves means for key railway hyperlink in Kolkata
“We have finally mitigated the challenges posed by the Bowbazar tunnelling crisis and successfully connected Sealdah and Esplanade Metro stations. The electrical works related to the aluminium third rail are also nearing completion, and the electrical inspector has been approached for the statutory EIG inspection of the third rail before it is charged,” he stated.
An entire visitors block on two Sundays was sought by Kolkata Metro Rail Company Ltd. which was instantly granted, the official added.
East-West Metro, also referred to as Inexperienced Line, will save round 90 minutes for each day commuters who at the moment must journey between Howrah and Sealdah in overcrowded, slow-moving buses or pollution-causing taxis.
“A request for full closer of Green Line service from February 8 to March 24 has been submitted by KMRCL. The demand has not been approved so far,” the official added.
A Metro Railway engineer defined, “Green Line of Metro Railway, Kolkata, is the first corridor where CBTC signalling system has been commissioned for safe and automatic train operations.”
“In addition to automatic train protection to prevent collisions, speeding and red light passing, this system will allow the Metro rake to operate in Automatic Train Operation mode, where all rakes will communicate their position, speed, acceleration, and deceleration,” he added.
“The system is designed in such a way that the train driver acts as an observer, with the primary tasks of closing doors and pressing the train start button under normal conditions. In the event of an earthquake or emergency, a single button press at the control centre will stop all trains simultaneously, similar to how Japan manages emergencies. This feature is not possible with the existing North-South Corridor . With the same CBTC system, metros in London and Moscow operate with a 90-second headway, which is not achievable with other signaling systems,” he stated.
At the moment, Metro Railway Kolkata operates companies on the East-West Hall in two elements: Inexperienced Line-1 and Inexperienced Line-2 . There was a lacking hyperlink between Sealdah and Esplanade as a result of Bowbazar cave-in 5 years in the past, which affected tunneling work however was resolved final December.
“Now, the journey begins to establish the CBTC signaling system for the entire corridor as a unified whole, not as two separate corridors. Unlike rail track, tunneling, or third rail works, where the completion of a missing link means the job is done, the completion of the CBTC system means integrating the entire route into one complete unit,” the official defined.
“KMRCL had requested a 45-day block to validate the newly installed software to fine-tune the software. If any issues arises, reports will be sent to overseas laboratories for adjustments. Once the software is fine-tuned, it will be reloaded, and the verification cycle will continue,” the official stated.
Earlier than commissioning Inexperienced Line 1’s 5-km stretch, 5 rakes had been run for a complete of 10,000 km, conducting over 1,000 trials to safe third-party certification for secure operation.
“KMRCL plans to conduct similar trials across the entire stretch with the revised software. To obtain approval, KMRCL must ensure a 100 per cent foolproof system,” the official added.
As soon as the security and reliability of the state-of-the-art signaling system are confirmed, the whole put in system could also be submitted to a world Unbiased Security Assessor . After receiving the ISA certificates, the Chief Railway Security Commissioner will conduct a statutory inspection earlier than granting permission for the business use of the whole hall, he added.
