okay . what is your destination ? there are 10 trains on that route starting at 05:50 . to make sure i book the right 1 what time do you need to arrive ? alright , there are 8 options . the earliest train after 09:15 leaves at 09:50 and the latest at 23:50 , each takes 17 minutes . do you have a preference ? your tickets have been booked . your total is 26.4 gbp and will be payable at the station . your confirmation is 04q2g0gu . that gives us about 17 options . is there a certain area in the city you prefer to stay in ?
