Starting tomorrow, passengers using Mumbai Central will be able to access high-speed internet as it becomes the first railway station in the country to get Google ’s wi-fi service.This is part of Google's tie-up with state-owned RailTel Corp. of India to provide wi-fi connectivity at 407 stations. It will be Google’s biggest such project here.Google CEO Sundar Pichai, during his visit to India in December, had given a January deadline for the facility at the first station. Extending support to the Digital India initiative, Pichai had said that 100 railway stations will be covered by 2016-end. Railway officials said that the project was on track and will meet the deadline.RailTel's fibre optic network is being used as the backbone connecting the stations. Officials told ET that high-speed connections will be available for all users, many of whom may not be online otherwise.Pichai, on his blog, had promised connectivity that was “many times faster than what most people in India have access to today.”Passengers could use it for anything from downloading a book or a game for their journey, watching videos or researching their destination.
