Hello, I'd like to find a train to Cambridge on Thursday please. 
And where will you be leaving from?
I would like to leave from Stansted Airport after 11:45.
I can book you on train TR9775 leaving Stansted Airport going to Cambridge Thursday at 12:24, will that work?
How much does it cost and when does it arrive?
It arrives at 12:52 and costs 10.10 pounds. Would you like a booking?
Not at this time thank you.
Ok. Is there anything else I can help you with today?
Nope, that's all I need. Thanks!
Thank you and have a great day!
