transport system of london

I previously mentioned that I am really impressed by the transport system of London. Here if you want to go anywhere in UK and you know either the address or the postcode of that place, then you have no worries to reach the place. You simply need to put your address and address of the place, where you want to go at the website of transport for London and it will tell you how to reach your destination, which train you have to take and after leaving that train what bus you have to take and after how many minutes of walk you will reach your destination. You have no need to ask every body that tell me how can I go at this place...
