There are many trains out of Cambridge. What destination are you thinking of? 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?
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. That would work! Could you tell me the Train ID, Arrival Time, and Price?

Sure TR8531 arrives at birmingham new street station at 19:44. The cost is 75.10 GBP per ticket. Can I help with anything else today?
