Task-oriented dialogue about: train

Hello, I need a train to come in at 8 am.
Where would you like the train to take you?
I need to leave from cambridge and get to Kings Lynn by 8:00 on Saturday.
The TR2973 leaves from cambridge on Saturday at 07:11 and arrives at kings lynn at 07:58. If you want one that leaves more time there is one an hour earlier.
That one will work, can you get me 7 tickets please?
Alright, I've booked that and it was successful. Your Reference number is D2D4VN6F and the total fee is 62.72 GBP. Anything else?
That's all for today. Have a great one!
Thank you, you have a great day as well. Let me know if you need help with anything else.
