What does the man mean?

W: The map shows that this street goes downtown.
M: Yes, but what we want to know is how to get to the park.

W: Excuse mc. Could you tell me when the next train to Manchester leaves?
M: Sure. Well, it’s three now. The next train to Manchester leaves in two hours. But you can take the train to Leeds, which leaves in fifteen minutes and then get off at Manchester, because it stops at Manchester on the way.
