I can assist you with that. There are many options available to you leaving London Kings Cross arriving in Cambridge, what day and time would you prefer?
I need a train from London Kings Cross to Cambridge. I want to leave on sunday, and I want to leave after 0930 am.
{"__type": "Inform", "entity": {"__type": "Train", "choice": "many", "departure": "London Kings Cross", "destination": "Cambridge"}} {"__type": "Request", "service": "train", "values": ["day", "leave at"]}
{"__type": "Inform", "entity": {"__type": "Train", "leave at": "11:17", "trainid": "TR7147"}}
TR7147 departs at 11:17 would that work?
