Does anybody know why Chicago Metra commuter trains are always hauling around empty passenger coaches. It seems like on a typical Saturday or Sunday the trains will pull 7 or 8 coaches with only 2 or 3 of them carrying passengers. I can understand that sometimes empty coaches will need to be taken to Union Station or the outlying terminals to prepare for rush hour, but it seems like EVERY Metra train carries empty coaches. I have actually seen Metra trains with 2 locomotives pulling 8 coach cars of which only 3 had passengers. Isn't this kind of wasteful, especially at taxpayer expense?
