There are several trains available. Could you specify which day?
I'm in need of a train that leaves from Peterborough and arrives by 18:30. I would like to travel on Monday and my destination is Cambridge.

{"__type": "Inform", "entity": {"__type": "Train", "arrive by": "6:09", "leave at": "5:19"}}
I have a train that leaves at 5:19 and arrives by 6:09. Does this work for you?
