generate response: The train that arrives closest to 16:45 is best. I just need to know what time it leaves and arrives. Oh and of course it's ID.. Intent: find_train. Slots: train-arriveby=16:45, train-day=sunday, train-departure=london liverpool street, train-destination=cambridge
Response: Of course! That will be TR6578 leaving at 13:39 and arriving at 15:07. The price is 13.28 pounds and it's an 88 minute duration. May I help with anything else?
