Hi, I'm looking for a train to Stevenage.
There are several.  When do you plan on leaving?
I would like to leave sometime after 11:00 on tuesday.
There are 7 trains with that criteria.  All of them are leaving from Cambridge, leaving after 11.  Is there a certain time you would like to arrive by?
I would like the train that leaves as close to 11:15 as possible please.
I have one that leaves at 11:21. How many tickets please?
I want to make a booking for 5 people.
Booking was successful, the total fee is 64 GBP payable at the station.  Your reference number is 5DHIPIME.  Can I help you with anything else?
