Google is well-known for snapping up the teams behind various cogs in the wheel of the travel industry - and this week it has flexed its muscles once again.
The search giant has acquired Where Is My Train?, a popular mobile app in India that sells seats on the country's vast rail network and provides timetables and live train information to commuters.
Terms of the acquisition have not been disclosed.
Google was said to be one of a number of backers looking to invest in the company over the course of the summer of 2018.

But it has since decided to take the service and the Sigmoid Labs team that built it under its wing.
Sigmoid was created in 2013 with, in its own words, "a mission to use technology to improve the lives of millions of Indian train travelers."
The app is unique in some respects, given that it works in both on and offline modes.
In a statement, Sigmoid Labs says: "Over time, we’ve improved the app to make it even more convenient and useful, and we’re thrilled with the response that we’ve gotten from users. The confidence that our users have placed in us is what makes us so excited to think even bigger."
The deal will probably not go down in Google acquisition folklore as one of its most high-profile in the travel sector (ITA Software and Frommers will take those accolades), but it sits alongside a number of smaller buys (such as Ruba) that have, over time, given the company the expertise and technology to bolster its focus on the industry.
On the latest deal, a Google official says: "We are excited that they’re joining Google and will be part of a team that will continue to build on the current offering and more."
