Hi I need to get to Cambridge by 5:30 PM. Is there a train for that?
There are multiple options that will get you to Cambridge by 5:30pm.  Could you please tell me where you will be departing form and what day you are traveling?
I will be departing from Norwich on Wednesday.
TR0033 departs Norwich at 15:16 and will arrive in Cambridge at 16:35 (4:35p.m.). Would you like a ticket on that train?
That would be fine.  How long is the trip?
The trip is 79 minutes. 
Thank you for the information!
And you would like to book just one ticket, is that correct?
Yes, one ticket is fine.

Nope, that's it! Thanks!
