Where would you like to leave from?
I need to find a train leaving on Thursday going to Cambridge. I will be leaving from leicester. Also, I need something that will get there by 14:15.
{"__type": "Request", "service": "train", "values": ["departure"]}
{"__type": "Inform", "entity": {"__type": "Train", "arrive by": "13:54", "trainid": "TR8882"}}
TR8882 will arrive by 13:54, would that work for you?
