I need help booking a train from cambridge to ely.
Ok, what day are you traveling?
Tuesday and I need to leave after 16:45 please.
Yesm there is a train available, the TR7733, and leaves at 17:50. Would you like me to book this?
Yes please book it for 8 people and provide the reference number. 
The train is booked for 8 people and the reference number is OPGQ4971. Do you need any other assistance?
Yes, I'm looking for a college to visit in town. Can you give me some info on what's around? 
I would be happy to get that information for you. Can I help you find a restaurant or an attraction? Or would you like assistance with accommodations?
I am particularly interested in colleges if you would focus on that type of attraction. I would appreciate it.
There are 18 colleges in town. Do you have an area preference?
Are there colleges in the centre of town?
Yes, there are 13. I personally recommend corpus christi. Entrance costs 2 pounds. The address is king's parade, postcode is cb21rh, and phone number 01223338000. 
Great, thank you so much! That will be all for today.
You are welcome. Please let us know if you need anything else. Have a great day!
