I have 1,029 trains departing cambridge, to narrow it down what is your destination and on what day would you like to go?
I'm looking for a train that departs Cambridge after 10:00. I'm looking to travel to Birmingham New Street, and I want to leave on Thursday.

Great, I can get you a ticket for that train. How many people are riding with you?
