Hi, I'm looking for a train that's departing Cambridge and going to London Liverpool Street. 
I have the listings up for you, what date and time will you need that train?
I need to travel on Thursday, and I need to arrive by no later than 16:15.
There are 5 results, depending on when you want to leave. There is a train that leaves at 11:59 and arrives by 13:27, will that be ok?
Yes, that will work can you book that for me?
Yes I can book that for you. How many people will be needing tickets?
I need tickets for 8 people. 
Your reference number is OWVUY7ZZ. The total fee is 132.8 GBP payable at the station. Do you need anything else?
Thanks and yes, now that you asked, I really would like to check out some colleges in the centre
You're in luck, we have 13 colleges in the centre. May I recommend Christ's College for you? It has free admission.
could you please provide the address, phone number, and entrance fee.
Christs College is on St. Anfrews st. and phone is 01223334900
