Google said on Monday that it is winding down its Station program, through which it rolled out free Wi-Fi in more than 400 railway stations in India and in several other public places around the globe. Caesar Sengupta, VP of Payments and Next Billion Users at Google, said the program, launched in 2015, helped millions of users connect to the internet everyday — many for the first time. But as mobile data prices become affordable in many markets, Google Station is no longer needed.
