I am looking for a train leaving Peterborough on Thursday.  Can you help me?
many trains leave, what time do want to leave?
I need to depart after 20:00, and will be travelling to Cambridge.
Okay how about the TR8185 that leaves at 20:19 and arrives by 21:09. 
Okay, that will do. What is the travel time?
The travel time for that route is 50 minutes. Did you need a ticket?
Yes, I also need places to go in college.
There are many colleges to visit in Cambridge. May I suggest one?
Yes, I would like that. 
pembroke college is in the centre located at trumpington street with a free entrance fee.
That sounds perfect, may I have the postcode please?
Absolutely! The postcode is cb21rf. Is there anything else I can help you with?
That's it. Thanks for everything.
You are welcome.  Enjoy your time in Cambridge.  Good bye.
