I agree, so do I - which is like never. My new 'local line' built at great expense on an old freight line runs frequently, and empty most of the time. Why? Because it carefully avoids most shopping centers and other centers of activity along its route. One exception, a loop that goes to the local university, or at least to within 2 or 3 hundred yards - clever planning!
One end of this local line actually connects with the 'main line.' Where does that go? Well it certainly does not go anywhere near, or stop at any of the 4 airports - really good planning eh?
As I said, I use it when it makes sense for me.
P.S. Has anyone flown into Frankfort or Heathrow airports - those are examples of convenient mass transport connections.
