I'm looking for a train to stevenage that leaves after 11:45
The first train to Stevenage leaves at 13:21 on either Wednesday or Friday.  Which day will you be leaving?
I need to leave on Sunday from Cambridge.
On Sunday TR0523 leaves at 13:21, would that work for you?
Yes, I think that will be just fine. Can you please tell me how much it will cost?
It is 10.24 pounds per ticket. Can I book that for you?
Yes, that will be fine. I am also looking for museums in the centre.
I have 11 different choices. Might I suggest the Primavera. They just added many new exhibits. 
Sounds great, what's the post code? 
The Primavera's postcode is cb21sj. Is there anything else you need help with?
No that is all I need.
Okay. Glad I could help.
