TRANSPORT

Exploring Mars is going to be very exciting, but for now, it's easier to explore our own planet! In particular, London.
We're going to follow Freddie as he explores all the different kinds of transport in London.

The next part of Freddie's journey is on a another kind of train called Docklands Light Railway. These are computer-controlled trains with no drivers.
The different kinds of transport link up pretty well but sometimes you have to walk from one point in the journey to the next.

People use lots of other forms of transport in London. Some people use boats on the River Thames to go to walk

There is one kind of transport that isn't very good in London - and that's the car. They move very slowly because there is too much traffic.
