My hometown

Hello, my name is Lisa. I live in London. I often go back to my hometown to visit my grandparents. They live in the north of England. First, I go to the London King’ Cross railway station by Underground. It takes me about half an hour. After that, I take a train to my hometown. It takes me four hours to get there. I prefer travelling by train because I can enjoy the scenery on the way. It takes about ten minutes to walk from the local railway station to my grandparents’house. I always have a wonderful time in my hometown.

How long does it take her to travel there by train ?
