If you've ever visited London, you are likely familiar with "The Tube" which is London's underground rail network that operates throughout many areas of London. You should be aware that the Tube is not the only public transport available: there are also buses, overground trains and the Docklands Light Railway--all of which use the Oyster card in zones 1-6. The "Greater London" area, which basically includes all areas within the M25 ring road, has six travel zones. Zone 1 covers central London and zone 6 is the farthest away from the centre. (The zones are situated around the city centre quite like a target, each successive zone being a ring around the first as noted in the map below).
Cost of Transport
How much you need to pay for transport depends on where you are working or attending university and where you live. Familiarise yourself with your expected travel routes before you set out house-hunting. Depending on how much you will travel and the time of day (more expensive during peak morning and evening hours), it may be more economical to purchase a weekly, monthly or annual travel card rather than single journeys. If you are not going to travel into Zone 1, or are only going to do so rarely, it is possible to buy travel cards which are much cheaper.
By midnight, most public transport closes, apart from night buses. So if you work late or have a long night out, it may take longer to get home if you live farther outside London.
