*Google Maps will soon tell you when it’s time to get off your train or bus*

Google is about to launch a small but useful update to Google Maps that will give you live guidance and interactive real-time notifications during your journey.

These updates will appear in the Google Maps app and, maybe most importantly, on your Android lock screen.

What's new here is that you'll soon be able to tap a "start" button at the bottom the screen with the details about your transit journey and then get live updates as you walk or ride on your local buses and trains.

While Google Maps always did a good job of giving you detailed transit directions, the process generally involved keeping track of your own progress along the route.

We expect this update to go live soon - and Google may already be testing it outside of its trusted tester community.
