U: I'm looking for a train from Ely to Cambridge. Do you have any?

S: Yes, there are quite a few.  Is there a day and time you would like to travel?

U: Yes, leaving on Sunday at 10:00 AM

S: The best time matching your criteria is a departure from Ely at 11:35. Will that do?

U: I'm sorry, my travel day is actually Thursday, not Sunday. I need to arrive by 14:45.

S: I have a train TR4068 leaving at 5:35 and arriving at 5:52. Would you like to make reservations?

U: Yes, please make reservations.

S: Your reference number is : MUBTUUTM. Can I help with anything else?

U: Did you book for 5 people? Is there a train that arrives closer to but before 14:45? Thanks.

S: I apologize about that. The closest I can get you there is on train TR4992 which will arrive at 13:52. Would you like me to book it for 5 people?
