Late last year, Google CEO Sundar Pichai outlined a project that would bring free public Wi-Fi access to over 400 train stations across India. Today, the search giant has rolled out the service at Mumbai Central, a railway station through which over 100,000 people pass through on a daily basis. Over 100 stations will be covered by the end of 2016, with Allahabad, Patna, Jaipur and Ranchi next in line to get free Wi-Fi.
