Bus and rail networks in Britain are very well developed, offer frequent and efficient services and provide access to the rest of England. By the tube and buses you can go to all London airports (Luton, Stansted, Gatwick, Heathrow, City Airport).
Kids' Travel Discounts -- Children under 10 (accompanied by an adult), travel free on public, including Tube, Overground, DLR, bus, and regular rail services. Children in this age bracket who look older than 10 should carry photo ID.
Children aged 11 to 15 carrying a 11-15 Zip Oyster photocard travel free on buses and trams, and pay child fare on Tube, Overground, DLR, and regular rail services -- up to a maximum of £1.30 for unlimited off-peak journeys in one day. To obtain a Zip Oyster photocard, apply online at www.tfl.gov.uk/zip. There's an administration fee of £10, and you'll need to upload a photo. Postage is free to U.K. addresses, and overseas visitors can arrange to collect their card at any Travel Information Centre.
It's the same for anyone aged 16 to 18. The 16+ Zip Oyster photocard gets you single tickets at half the adult price on bus, Tube, tram, and Overground services, as well as child-fare Travelcards.

One of these maps shows only the Tube stations, while another also shows train and tram connections in central London.
You can obtain a free printed copy of the Tube map at an underground station or at a Travel Information Centre.
To see a street map of the area around an underground station, choose "Tube Map" from: http://www.multimap.com. Click on the part of the map in which the station is located to zoom into that area, then click on the station name.
It is wise to check if there are problems with Tube services before you travel, especially if it is important to arrive on time.
Problems with the normal services are common. Planned engineering works are often carried out at weekends or on public holidays: replacement bus services should operate, but journey times may be much longer than normal.
