I am looking to get a train to cambridge from kings lynn
I can certainly help with that. When did you want to travel? 
depart from kings lynn at 20:30 and leave on Sunday.
There is a train leaving at 21:11 and it costs 7.84 pounds, would that be good for you?
My mistake I need the train to arrive by 02:30 on Sunday.
There are no trains at that time would you like to try a different time?
Not doing well, I actually need to arrive cambridge at 20:30.  I should leave on sunday.
TR6697 departs Kings Lynn at 19:11 and arrives at Cambridge at 19:58. Would you like me to book this for you?
Could you tell me the price of this ticket?
Sure the ticket is 7.84 pounds a ticket.
