Ok thanks, Im ready to book.
Great, I have booked your ticket, your reference number is : 9LLWMNOM. May I help with anything further.
I'm so sorry. I didn't mean to book yet. I won't need that reservation. Could you make sure that train TR3390 is departing from London Liverpool?
Train TR3390 is departing from peterborough to cambridge. Would you like me to look for a train departing from London Liverpool?
