I want to book a train for Friday. OK, what are your departure and arrival stations, and what time are you traveling? I want to go from Cambridge to London Kings Cross on Friday. Is there a time you would like to leave by or arrive by? Yes, I'd like to arrive by 10:15. TR8026 arrives at 7:51 and TR2000 arrives at 9:51. May I book one of those? I'm not looking to book at the moment, can I just get the travel time and price for TR2000? Thanks! Sure travel time is 51 minutes and total cost of the ticket will be 23.60 pounds. Anything else I can help you with?
