can you help me find a train ? i'll be traveling on wednesday . oh , of course . sorry . i am leaving out of leicester and going into cambridge . i want to arrive by 16:15 . i do not have a preference on leaving time .
what is your departure point and what time would you like to depart ? is there a specific time you want to leave or arrive by ? i have 2,828 trains to pick from . i need to narrow this down . that narrowed it down to 10 options . what time would like to leave ?
