What is your departure site and what day are you traveling on?
I need to locate a train that's going to Cambridge and leaves after 13:45 PM. Can you help? I need to depart from london kings cross on thursday.

{"__type": "Offer", "entity": {"__type": "Train", "leave at": "15:45"}}
To clarify, do you need to leave after 13:45, or after 15:45?
