Hello there. Can you please find me a train schedule that leaves on Wednesday heading for Cambridge?
Yeah, I can do that. Where are you heading in from?
I'd like to leave from Broxbourne sometime after 12:30. 
I have 12 available trains. The first leaves at 12:32 and arrives at 13:32. Would you like me to book that for you?
May I have the train ID for that one?
Certainly. That train ID is TR7834.
What is the travel time?
Travel time will be 60 minutes.
Thank you. That is all I will need.
Perfect! Have a wonderful day!
