I am looking for a train to Ely.
What day are you looking to travel?
I need to leave a little after 8:00 on Sunday, and I'm leaving from Cambridge.
The closest train I have is the TR3177 that leaves at 09:50. There's nothing earlier on that day. 
That will have to work. What is the arrival time?
The arrival time is 10:07. 
Perfect! That's all I needed to know. Thanks. Have a great day.
Have a wonderful day!
