Task-oriented dialogue about: train

I need a train from london liverpool street station on wednesday.
What is your destination, please?
I am heading to Cambridge for an important visit. Can you get me there by 11:00?
There is one train leaving at 7:39 arriving at 9:07 would that work for you?
That should be perfect. How many tickets can I get?
You can buy up to eight tickets.
Just one is fine.
Ok. The price is 16.60 pounds for 1 ticket. Do you want me to book it?
Could you tell me the travel time please first?
Yes, it's 88 minutes. May I help with anything else?
That's all the info I needed today, thank you for your help!
Thank you! Have a wonderful day!
