"I'm very proud to announce that it's the train stations of India that are going to help get millions of people online. In the past year, 100 million people in India started using the Internet for the first time," Google's India-born CEO Sunder Pichai said in a blog post yesterday after his meeting with Prime Minister Narendra Modi.

This means there are now more Internet users in India than in every country in the world aside from China. But what's really astounding is the fact that there are still nearly one billion people in India who aren't online, he noted.

Pichai said Google would like to help get these next billion Indians online so they can access the entire web and all of its information and opportunity.

"That's why, today, on the occasion of Indian Prime Minister Narendra Modi's visit to our US headquarters, and in line with his Digital India initiative, we announced a new project to provide high-speed public Wi-Fi in 400 train stations across India," he said.

Working with Indian Railways, which operates one of the world's largest railway networks, and RailTel, which provides Internet services as RailWire via its extensive fiber network along many of these railway lines, Google's Access & Energy team plans to bring the first stations online in the coming months.

The network will expand quickly to cover 100 of the busiest stations in India before the end of 2016, with the remaining stations following in quick succession, he announced.
