I'd like to find a train to peterborough. There are 266 trains going to Peterborough. Can you give me a departure day and time so that I can narrow down your choices? I am looking to go from cambridge, and go on friday arriving by 14:30 Okay, how about the TR5901 leaving at 13:34 and arriving at 14:24 with a duration of 50 minutes? The cost is 16.50 pounds. Would that work for you? That would be perfect! Great, how many tickets would you like to purchase? 7 tickets please. Can I also have the reference number for the booking? Your tickets are all booked, reference number R5P65TW5
