Google Maps has incorporated train timetables for a while now, but it's never accounted for the inevitable delays and cancellations that plague UK networks. You would select what you think is the fastest route, only to stand around on the platform wishing you had called a taxi instead. Well, that could be less of a problem in the future, if you're a Google Maps user at least, because today the company has added real-time National Rail data to its travel app. So if yet another signal failure is disrupting your line, the app should reflect that automatically and give you some alternative routes. In addition, you can now swipe around the map and tap on any UK rail station to review the next departures -- helpful if you're stuck in the middle of nowhere and need to start making tracks.
