Hi, I am looking for a train.  I need to leave on Tuesday, after 11:15.
Can I get information where you are departing from?
I'll be going from Cambridge to Peterborough.
I have train TR8806 departing at 13:34 and arriving by 14:24. Would that work for you? If not, I have both earlier and later trains. 
That works. Book it for me. I need the reference number.
The booking was successful and your total fee is 16.5 GBP. You pay that at the station. Your reference number is M1C9IXIH. 
Can you also help me find some kind of architecture attraction in city centre?
great saint mary's church is an architecture attraction in the city centre. 
That sounds good. Can you give me the address, please?
Postcode cb23pg, Market square. Is there anything else you would like to know. 
No, that's all I need for now. Thank you so much.
No problem! Have a great day!
