i am wanting a train that leaves on friday and goes to cambridge . i want to leave after 16:45 , depart from birmingham new street .
sure thing . what s your departure site and around what time would you like to leave ?
{'service': 'train', 'act': 'inform', 'slot_name': 'arrive', 'value': '20:23'} {'service': 'train', 'act': 'inform', 'slot_name': 'leave', 'value': '17:40'} {'service': 'general', 'act': 'reqmore', 'slot_name': 'none', 'value': 'none'}
the first train will leave at 17:40 and arrive at 20:23 . does that sound good ?
