i am looking for a train leaving on tuesday . i am leaving from leicester and should arrive in cambridge by 13:45 .
sure , what stations are you traveling between ?
{'service': 'train', 'act': 'inform', 'slot_name': 'choice', 'value': '7'} {'service': 'train', 'act': 'inform', 'slot_name': 'leave', 'value': '5:09'} {'service': 'train', 'act': 'offerbook', 'slot_name': 'none', 'value': 'none'}
there are 7 trains that match your request . the first train leaves at 5:09 . do you want me to book that train or do you want information for other trains ?
