Can you help me find a train? I am looking for that departs from Cambridge on Saturday.
There are 202 trains leaving from Cambridge on Saturday. Can you give me a destination point so that I can narrow it down for you?
I would like to go to Birmingham New Street and the train should leave after 14:15.
The TR3735 leaves at 15:01, will that suit you?
That would be great. Can you get me 7 tickets on that train?
Alright, you booking was successful, your confirmation number is KU1R7NQO.
Ok. Is that also the reference number? Thanks.
That's correct, the number I gave you was the reference number you'll need.  You'll need to pay 420.56 GBP when you get to the station.  Is there anything else?
Okay. Thank you very much.
Is there anything I can help you with today?
No, that would be all. Thanks. Have a night day. 
Thank you.  You have a night day as well.
