{'service': 'train', 'act': 'inform', 'slot_name': 'arrive', 'value': '17:51'} {'service': 'train', 'act': 'inform', 'slot_name': 'leave', 'value': '17:00'} {'service': 'train', 'act': 'inform', 'slot_name': 'depart', 'value': 'cambridge'} {'service': 'train', 'act': 'inform', 'slot_name': 'dest', 'value': 'london kings cross '} {'service': 'train', 'act': 'inform', 'slot_name': 'id', 'value': 'tr0945 '}
