London Underground ticketing

London Underground is a big train system that goes all around London. To ride on the trains, you need to have a ticket.

You can buy tickets at machines inside the stations. These machines look like big computers with buttons and a screen. You choose which type of ticket you want and put in your money or your credit card to pay.

Some tickets are for just one ride on the train, while others are for a whole day, a week or even a month. The more you use the trains, the better value it is to buy longer tickets.

Once you have your ticket, you need to put it through a machine called a "gate" to get on the train platform. The gates have a little scanner that reads your ticket and checks if it's valid. If it's okay, the gate will open and you can go through.

When you get off the train at your stop, you need to put your ticket through another gate. This time, the machine takes your ticket and keeps it, so you can't use it again.

If you lose your ticket or forget to buy one, you can talk to someone who works at the station. They can help you get the right ticket and tell you how to use it. It's also a good idea to have some extra money with you, just in case you need to buy a ticket.

Overall, buying and using a ticket for the London Underground is like buying a special pass to take you on an adventure throughout the city. With your ticket in hand, you can explore all the amazing places and sights that London has to offer.
