I'm looking for a train that is going to birmingham new street and leaves after 17:15.
{"__type": "Inform", "entity": {"__type": "Train", "leave at": "18:01"}} {"__type": "Request", "service": "train", "values": ["day"]}
There's a train on that route every day departing at 18:01 that ought to work for you. Do you know what day you'll be travelling?
