I need to depart from Cambridge.
There is a train running from Cambridge to Bishops Stortford on Friday that leaves at 13:29. The train id is TR8585. Would you like me to book it for you?
No. I need the train to go from Cambridge to Bishops Stortford on Sunday and leaving after 13:15.
Alright, I have several options for you. The earliest train that meets your criteria is TR2402 and leaves at 13:29. Will that work?
