{'service': 'train', 'act': 'inform', 'slot_name': 'id', 'value': 'tr6939'} {'service': 'train', 'act': 'inform', 'slot_name': 'arrive', 'value': '07:07'} {'service': 'train', 'act': 'inform', 'slot_name': 'leave', 'value': '05:39'} {'service': 'train', 'act': 'offerbook', 'slot_name': 'none', 'value': 'none'}
