Yes, I would like a train ticket for Sunday. I'm going to London Kings Cross.
Sure. Where will you be leaving from?
I'll be leaving from cambridge, and I need to get to kings cross by 10:00.
The TR3207 leaves at 07:00 and arrives at 07:51. Would you like that one?
That sounds good. Please book it for 6 people and can I have the reference number?
Train TR3207 is booked for 6 people. The reference number is BAAL6J4H and the total fee is 113.28 GBP payable at the station.
Thank you. That's everything I needed.
Okay. Glad I could be of assistance.
