There are many trains out of Cambridge. What destination are you thinking of?
Can you tell me what trains will be leaving from Cambridge on Wednesday? I want a train to birmingham new street that leaves after 16:30.

I have one leaving at 17:01 on Wednesday, would you like me to book it for you or do you need one later than that?
