Task-oriented dialogue about: train

I'm looking for a train. The train should arrive by 21:30 and should go to bishops stortford.
What day will you be traveling?
I would like to travel on Monday.
There are 8 trains that match your search. Shall I choose one to book?
Yes, please choose the one closest to my arrival time.
I recommend the TR8244 which leaves at 19:29. How many seats do you want me to reserve for you and your party?
I actually only want the price, but can you make sure that the train is leaving from Cambridge.
Yes that leaves from Cambridge and there are many other times with an earlier departure time if you'd like. The price is 10.10 pounds.
That is perfect thank you very much for all of your help. You have a wonderful day.
Thank you, goodbye!
