I'm looking for a train that leaves Cambridge on Sunday.
Alright. What is your destination?
I want to go to Peterborough.
I have TR7423 that leaves at 05:00 and arrives at 5:51. Would you like me to book this? 
what time in minutes does the journey take?
The trip takes a total of 51 minutes. Is there anything else you need?
I am also looking for places in the centre of the town to visit for architecture. Do you have any suggestions?
There are several. The churches are very nice, I especially like Holy Trinity Church. Does that sound like what you're looking for?
Sure that works. What's the entrance fee?
There is no entrance fee at Holy Trinity Church.  Can I help you with anything else today?
No, thank you. goodbye!
Have a lovely day!
