I'd like to find a train that departs from Ely on Monday, please!
Ok, I just need a little more information. What's your destination and what time would you like to leave?
I need to leave after 13:15 and I am going to Cambridge.
We have 6 trains leaving after 13:15 on Monday. Was there a specific time you wanted to arrive by?
Any of them will do. Can you tell me the price, arrival time and train ID of at least one option?
I have the TR4849 that leaves at 13:35 and arrives by 13:52. It is 4.40 pounds. Is there anything else I can help you with?
I think that is all I need, thank you. 
You're welcome. Have a great day!
