I can assist you with that. Can you tell me where you would be departing from?
I'm looking for a train that goes to Cambridge and arriving by 17:30. I'd like to depart from Stansted Airport on Saturday.
{"__type": "Request", "service": "train", "values": ["departure"]}
{"__type": "Inform", "entity": {"__type": "Train", "leave at": "9:24 am"}} {"__type": "RequestAlternatives"}
Sure, their is a train that leaves at 9:24 am. Does that work?
