I need a train to cambridge that leaves after 13:30.
There are several trains that are going to Cambridge at that time where are you departing from?  
I'll be departing from Kings Lynn on Tuesday.
Train TR4840 leaves at 14:11. Would you like me to book it for you?
First, I'd like to know the arrival time for it.
That train arrives at 14:58. Is there any other information you need before making your decision?
No, thanks. I also need a room in the north with free parking. 
There are 2 hotels and several guest houses available in that area. Is there a particular price range you need?
As long as it is 2-star rated and moderately priced, I'm pretty flexible about all the rest. 
Okay we have the ashley hotel, would you like a booking?
Yes, please book the Ashley for 2 people and 2 nights starting Tuesday.  
Booking was successful. The Reference number is YN5OGYA7. What else can I do for you?
That should be all I need.  Thank you for your help!
You are welcome. Would you like for me to go ahead and book train TR4840 for you?
No thank you. Good bye.
Enjoy your trip!
