Task-oriented dialogue about: train

I am looking for a train departing from Cambridge.
There are many different options for trains departing Cambridge. What date and time do you need a train on?
I need to get to Peterborough on Friday, and I have to leave after 12:30.
The first train leaving after 12:30 is TR5650 and leaves at 12:34 to get you to Petersborough at 13:24. Would this suit your needs or would you like a later one?
I'd like to book this train for 7 people, if possible.
You're all booked! 7 tickets from Cambridge to Peterborough at 12:34. Your reference number is I9UBCZW2 .
Great. Thanks for all your help.
You are more than welcome. Enjoy the journey.
