There are 318 trains that fit your criteria. To narrow some information down, what is your destination, departure site and preferred departure time?
The train should go to leicester and should depart from cambridge. I don't care about the departure time.
There is a train leaving Cambridge on Sunday 05:21, and arriving at Leicester at 07:06 for 30.24 pounds. Would you like me to book this for you?
No, thanks. What's the train ID?
The train ID is TR2025.
Thanks for the info. What else is available that arrives around 20:45?
No, I am sorry there is not.
