Yes,  please help me book a train on Saturday. 
We have a large amount of trains that day, is there a specific location?
I want to go from london liverpool street to cambridge.
What time would you like to leave?
I want to leave after 08:45 please
The first train to London Liverpool street is at 09:39 and arrives at 11:07 in Cambridge. Does this time work for you? or would you like later?
