The Department for Transport has launched a public consultation about extending the pay-as-you-go travel zone around London. Take a look at the above map to see all the new stations that could be included, as far afield as Stevenage, Tunbridge Wells, Guildford and Stansted Airport.
Pay-as-you-go means just turning up to a station and tapping in with a contactless bank card (or other card — we'll get to that). So no more queueing for so long to buy a ticket that you miss your train. And no more time spent calculating exactly which ticket to get — the technology does it all for you.
