I need to book a train departing from Cambridge after 9:15.
Where are you heading to?
I am going to Stevenage, on Wednesday.
I was able to find a train for you at 9:21. Would you like me to book it for you?
Could you tell me what the price of this trip is?
It should cost around 12.80 pounds.  Anything else?
Yes, what's the train ID and what time does it arrive?
TR8913 will arrive by 10:10.
Great. That is all I need.
Okay. Glad I could be of assistance.
