Task-oriented dialogue about: train

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
Thank you so much. That is all I will need today.
Thank you for contacting Cambridge TownInfo centre. Have a wonderful day!
