i am in ely . i need to figure out how to get to cambridge by train . i need to travel monday and arrive by 20:45
what day would you like to travel ?
{'service': 'train', 'act': 'inform', 'slot_name': 'arrive', 'value': '19:52'} {'service': 'train', 'act': 'inform', 'slot_name': 'choice', 'value': '8'} {'service': 'train', 'act': 'inform', 'slot_name': 'id', 'value': 'tr6679'} {'service': 'train', 'act': 'select', 'slot_name': 'none', 'value': 'none'}
there are 8 trains that arrive before this time . the tr6679 arrives at 19:52 , which is the closest to your requested time . does that work for you ?
