Task-oriented dialogue about: train

I'm looking for a train please.
Certainly. On what day do you want me to look?
on tuesday from cambridge to norway leaving at 2030 hrs
I'm sorry, could you confirm your destination so I can get an accurate schedule.
I'm sorry, I meant norwich, not norway.
I couldn't get you to Norway but Norwich is much more doable. I've got the TR2181 to Norwich leaving at 20:36 with a fare of 17.60GBP. Would that suit you?
That would be perfect. Could you book it for 1 person and provide me a reference number?
4SSOKT22 is your reference number. What else may I do for you?
No, thank you. good bye
Okay, have a great time and be safe.
