"Whether you call London home or you're one of the expected 31 million tourists visiting the city this year, we know that the addition of service alerts to Google Maps will make your travels across the city easier, faster and more convenient," said Google executive Thijs van As.
Google integrated information on nationwide train timetables to its service earlier this year, enabling users to plan their journeys across the UK.

The live tube updates can be access via PC, Mac and Android devices.
