This is because different companies built the railways
And they all had their own station in london
Victoria and Waterloo for example, are the station for trains to the south. If you want to go to the west, however, you have to go from paddington. Today, Britain hasn't got a national railway
company. Instead, over 20 private companies run the trains.
You can also take a train from London through the Channel Tunnel to Paris and Brussele on a Eurostar train. These trains go from the Eurostar terminal inSt Pancras
