Task-oriented dialogue about: train

Hello, I'm looking for a train from Cambridge to Norwich.
Certainly, there are many trains going that route. Can you specify which day you'd like to travel?
Sorry. I want to leave on Saturday after 20:30.
There is a train Saturday at 20:36. Does that work for you?
Yes that works great can I book that for 5 people please?
I have confirmed booking for 5 tickets, your reference number is CID6UHHF . The total fee is 70.4 GBP payable at the station. Can I help with anything else?
Thanks, that's all I need. Have a nice day.
Great! I'm glad we could help.
