I have several possibilities for Monday. Can you specify your destination so I can narrow down my search? OK, when do you want to leave or arrive by?
I want to take a train to cambridge on monday, what's available? I am going to Cambridge, from Birmimgnham New Street. I'd like to leave after 17:00. When would I arrive?
{"__type": "Request", "service": "train", "values": ["arrive by", "leave at"]}
{"__type": "Inform", "entity": {"__type": "Train", "arrive by": "10:23", "leave at": "07:40"}} {"__type": "Confirm", "entity": {"__type": "Train"}}
There is train leaving at 07:40 that will arrive at 10:23,do you want that train?
