Possibly.  What is the price for that ticket? 
The price of that ticket would be 12.80 pounds.  Would you like me to reserve your ticket?
could you tell me how long the train ride will be?

That's all the information, about the train, that I need right now. Can you help me find a restaurant that serves Indian food?
Definitely! My favorite is Tandoori Palace, which is in the center and expensive. If you want something a little cheaper, I recommend Kohinoor.
