Google maps provide public transit information in London

Google has recently added public transit information to Google Maps London. This would enable travelers to plan routes in one of Europe’s largest metropolitan areas. The service shows all possible public transportation connections from one location to another using street addresses or points of interests such as restaurants. Click on “Get directions” and you’ll get suggestions for your trip. The service is also available on Google Maps for mobile, where it has an extra feature. It uses your current location to determine the best way to arrive at your destination. On Android devices, you can use the recently launched Transit Navigation option in Google Maps to get alerts when you arrive at your destination or when you need to transfer to another bus or train line.
