I want a train leaving on saturday. 
Where are you departing from, and what is your destination?
I am departing from bishops stortford and I would like to go to cambridge. 
There are no trains leaving from that location.
Hmm, can you double check? I would be departing from Bishops Stortford and going to Cambridge for Saturday. 
Of course! I have found 10 trains departing from Bishops Stortford towards Cambridge. Do you have a preferred time to leave or arrive by?

Train TR1382 leaves at 21:29 and arrives by 22:07, would you like me to book that for you?
