Hi, I'm looking for a train that leaves on Thursday and arrives by 18:30
Sure, which stations will you be using?
from cambridge to stansted airport.
There are 13 trains that match your needs. The first train leaves at 05:40. Do you want a ticket on this train or one that leaves later?
No thank you that will be all
Glad I could be of help.
Actually I do need the train ID and travel time please. 
Travel time will be 28 minutes for any train. The one closest to your arrival time is the TR5579, which departs cambridge at 17:40
Can you also get me the postcode for Nandos restaurant?
cb17dy is the postcode. Would you like to dine there ?
Thank you I will think about it. 
Great. Is there anything else?
No that is it. Thank you.
You're welcome, have a great day!
