i am needing help with your train schedules . i will be departing from birmingham new street and arriving in cambridge on sunday at 18:45 . i would like to leave no later than 19:30 . i do not care what time it is leaving but check again for it arriving by 18:45 .
what is your planned itinerary ? what time do you want to leave by ? there are no trains that match your criteria . can you verify the time you want to leave ?
