I'd be happy to help! Where are you coming from and where are you going? What time would you like to travel?
I need a train on Sunday. Coming from kings lynn to cambridge I need to arrive by 17:15.

There are several trains that meet your criteria. How early would you like to arrive? That will help me narrow down your choices.
