Task-oriented dialogue about: train

I'm looking to book a train that leaves on Wednesday after 12:45, if you could help me with this that would be great!
I'd be glad to help. But I will need a departure site and a destination.
I'll be going to Peterborough from Cambridge.
I would recommend TR1879 which leaves Cambridge at 13:06 and arrives in Peterbourough at 13:56.
I'm sorry, I had that backwards, I need a train that departs FROM Peterborough and goes to Cambridge.
I have over 20 trains traveling on Wednesday for you. Are you departure and arrival times still correct?
Yes they are.
I have train TR9545 which departs at 12:48 and will get you into Cambridge by 13:38. Does that sound like it would work for you?
Yes please book it for 1 person and provide the reference number
Your booking was successful. The reference number is 69YAY7YC . What else may I help you with?
Thanks for the service. Good day to you!
You're welcome! Please contact us again if you need anything else.
