Do you think we should travel by bus or by train ?   It's a difficult choice.The train is a little faster , but much more expensive .   We could face delays if we travel by bus , thanks to traffic jams .   Buses are more cramps and you can't walk around .   That's true.But I feel that I see more when I travel by bus .   Really ? I think you see more traveling by train .   So which form of transport do you prefer to use ?   I prefer going by train , even though it costs more .   Ok , then we'll go by train . I'm sure we'll have a good journey.Shall we go to the station and buy the tickets ?   The trains aren't usually full.We can get them on the day we travel.We should buy return tickets , because they are much cheaper than getting 2 singles .   We should take a packed lunch on the journey.The food they sell on the trains is always expensive .
