I want a train that is leaving from cambridge.
Sure, I can definitely help you with that.  When were you wanting to depart?  
I'm not sure. How long is the train ride? I would like to arrive by 13:45. 
TR5154 TAKES  88 minutes and leaves 05: 59. is that fine with you?
Is there another train on Monday that would get me to Kings Lynn closer to 13:45?
The TR7430 arrives in Kings Lynn at 12:58. It is 9.80 pounds. Would you like me to book that for you?
All I needed was the info on travel times, can you also help me find an attraction called Clare Hall?
Clare Hall is a college located in western Cambridge. It's located on herschel road. Do you need anything else?
No that will be all thank you. 
Happy to be of help. Goodbye.
