I want to go to a particular attraction called great saint mary's church.
Sure! great saint mary's church is in the centre.  What information do you need?
What is the postcode?
The postcode for that church is CB23PQ. Would you like their phone number?
No thank you.  I also need a train that should leave on thursday and should go to cambridge. 
Where will you be departing from? 
I will be departing from ely.
great, do you know your departure or arrival time?
I need to arrive by 15:15
I have train TR4068 leaving at 5:35 and arriving at 5:52.
I want to confirm that I will arrive by 15:15? You stated, leaving at 5:35 and arriving at 5:52?
I think the TR4992 train will work better.  It leave ely at 13:35 and arrives at cambridge at 13:52 on thursday. Would that one work?
Yes, I'm not booking my seat just yet. All I needed was the train ID, and you have given me that. Thank you.
You are welcome, any other questions today?
That's all I need, thank you!
I hope you enjoy your time here!
