Although I have a car, I prefer traveling by train, especially if I have to make a long journey. As the train travels at full speed through the countryside, I can relax, drink a coffee, read a book, or just
look out of the window, sometimes the movement of the train keeps me asleep, something you couldn't do while driving a car. The trouble is thet I hate waiting in cold stations, and I get angry when I have to waste time on looking for a taxi or a bus at the beginning or the end of my journey.
