No problem. Where are you leaving from?
Hi, I'm looking for a train to peterborough leaving after 17:00. Cambridge, on Tuesday.
{"__type": "Request", "service": "train", "values": ["departure"]} {"__type": "Greeting"}
{"__type": "Inform", "entity": {"__type": "Train", "choice": "several"}} {"__type": "Request", "service": "train", "values": ["arrive by"]}
There are several trains available. Is there a time you would like to arrive by?
