Three days from now February 25 union Railway Minister Suresh Prabhu will present his second rail budget in which there are two projects awaiting approval for Mumbai These are the VirarVasaiDivaPanvel suburban rail corridor and the CommunicationBased Train Control CBTC system The latter is said to be a breakthrough for improving frequency of the dense suburban system and for this a workshop was arranged for officials on February 17 by the Mumbai Rail Vikas Corporation MRVCThe first CBTC system has been proposed on the CSTPanvel Harbour line at a cost of Rs 4500 cr File picture for representationEven though the CBTC system is yet to be approved in the budget Prabhu had hinted at its approval as in his speech on February 17 he had said ldquoCBTC is the future of signaling and will emerge as a solution for Mumbairdquo The workshop took place in Mumbai mdash it was attended by officers from both Central and Western Railways mdash and an official from the Railway Board in Delhi read out Prabhursquos speech via video conferencingMore servicesThe first CBTC system has been proposed on the CSTPanvel Harbour line at a cost of Rs 4500 crore The railways claim that the frequency of trains shall drastically improve with it as the headway between two trains would come down from the current 240 seconds or more on the Harbour line to 150 seconds Officials who are studying this system claim that if it is implemented in totality then the headway or frequency between two trains would come down by 90 secondsThis would mean that in the current situation 1820 train services operate per hour and this will augment to 35 services or more after CBTC is in place But there is a flipside to it Railway officials feel that this system will work only if the Harbour line is made trespass free especially keeping in mind the recent deaths of school kid Gaurav Vora at Sandhurst Road and the four labourers who died near KurlaldquoAt least 65 percent of deaths on tracks occur due to trespassing With the frequency of train services improving drastically proper impenetrable walls need to be built along the rail linerdquo said a rail official Moreover there are level crossings at few stations that are open for vehicular traffic and people But the slums along the railway lines make trespass deaths more susceptibleldquoThe CBTC will help us double the number of train services But level crossings need to be eliminatedrdquo said S K Sood General Manager Central RailwayAt present the Central Railway CR has asked the MRVC to procure around 1820 air conditioned rakes that would have the CBTC system inbuilt These will replace the existing rakes plying on the Harbour line ndash currently there are 36 rakes ndash and then the two systems will be merged Each AC train with inbuilt CBTC will cost between Rs 100120 croreThe officials said that in a congested rail system like in Mumbai CBTC would allow them to run trains more frequently But for that they would not only need to make changes in the tracks and signaling but will also have to get new rolling stocks or rakes ldquoThe system by itself might cost Rs 1000 crore but when we look at it holistically including the new rakes and changes on field it would go up to Rs 4500 crore for the proposed one on the Harbour linerdquo said Prabhat Sahai Chairman and Managing Director MRVCThe railways will also keep the existing system as all trains wonrsquot be fitted with CBTC Sources said that under these circumstances the train will move at a controlled speed and its operations will also be merged with the existing system where brakes are applied in case a red signal is breached At the workshop the companies presented this technology in place across other rail systems in the world They also suggested a kilometre long test track and simulation centre in Mumbai where the CBTC system can be tried before it is implemented
