Travelling on the London underground presents few difficulties for visitors because of the clear colour -coded maps. It is always useful to have plenty of spare change with you because there are often long queues at the large stations. If you have enough change you can buy your ticket from a machine. You will find signs which list the stations in alphabetical order, with the correct fares, near the machines. There are automatic barriers which are operated by the tickets. You should keep the ticket, because it is checked at the destination.
由于英国地铁图清晰且彩色编制，乘客乘坐地铁不会有太大问题。一些大的站点购票经常排长队，所 以最好随身携带零钱。这样你就可以通过购票机购票了。在购票机旁，标记有按照字母表顺序排名的 站名以及费用。自动障碍门由车票操控并在终点站时进行检票，所以，你必须保存好车票。
