I'm planning a trip to Cambridge and need info on trains.  I am coming from Birmingham New St.
I can find you quite a few trains for your trip. On what day will you be traveling, and at what time would you like to depart? 
I will be leaving on a Tuesday and I would like to arrive by 17:30.
TR4887 leaves at 05:40
Great can you book that for one person?
Done and done! Booking was successful, the total fee is 75.09 GBP payable at the station. Your Reference number is : Q649D1SU.
Thanks!  Can you help me find a college to visit in the centre?
I'd be glad to. We have 13 colleges in the centre. Most are free to visit, such as Christ's College over on Saint Andrew's Street.
I have heard of Christ's College. Is there a more detailed address? I would also like their phone number, please.
I only have an address of St. Andrew's Street, but the phone number is 01223334900 if you would like to call them. Anything else I can help with?
No, you have been very helpful, thank you.  Good bye.
Enjoy your visit to cambridge and gave a good day.
