hello , im looking to book a train from broxbourne to cambridge i am leaving on sunday . i would like to arrive before 20:30 .
what day will you be travelling ?
{'service': 'train', 'act': 'inform', 'slot_name': 'arrive', 'value': '19:32'} {'service': 'train', 'act': 'inform', 'slot_name': 'leave', 'value': '18:32'} {'service': 'train', 'act': 'inform', 'slot_name': 'id', 'value': 'tr1428'}
the latest train that will arrive before 20:30 would be train tr1428 . it departs at 18:32 and arrives at 19:32 . would that work for you ?
