Task-oriented dialogue about: train

I need a train from London Kings Cross to Cambridge.
I have 70 trains travelling that route. To narrow it down, what day would you like to leave and what time would you like to depart/arrive?
sure, I would like to go on Saturday, and arrive by 20:20. As close to that time as I can arrive.
I have a 19:17 from London that arrives at 20:08. Would that work for you?
Yes, let me have 7 tickets, please.
Booking was successful, the total fee is 132.16 GBP payable at the station. Reference number is : QMD5P3EG . Is there anything else I can help you with?
No, that's all I need. Thanks.
Thank you for contacting Cambridge TownInfo centre. Have a wonderful day!
