The system does not exsist for your amusement. It exsists first and foremost to carry New York residents from point A to point B. That you happen to derive enjoyment from such an activity is but a minor consequence that somewhere under 5% of all riders of the system experience. As such you cannot expect the NYCTA to bend to your quite minority opinion of their operations.
Perhaps instead of bitching about the operators who are kind enough to allow you to donate 40 dollars to a noble cause and get a free train ride out of the deal, you'd instead like to thank fucking gawd that you have a system which has maintained a fleet of cars from it's rich history for your riding enjoyment. It is very easy for an agency to simply throw their cars away after their useful life is expended. It is quite another thing when people within the organization realize the potential benefits to keeping around a few of the old cars, indeed I would say that it is that distinction which separates the true transit agencies from the also-rans.
Instead of just running your mouth off and wasting a post with bitching about the kind volunteers who put in time to not only run your train, but also restore, maintain and paint it. And also to the system who supports their activities, even if it's only through tacit approval.
Once again, give a hand to C division, without them the centennial would be rather boring.
