W：Does the number nine train stop at this station?

W：Where can I catch the shuttle bus?
M：At this time of the day， you can get it where the other city bus lines stop，behind the main entrance to the terminal. But during rush hours，it stops at the side entrance. The next one leaves in about ten minute.
