I remembered a splendidly flakey idea I had some years ago: how about a limited-run C&S Burlington Route Everywhere West / Way of the Zephyrs On30 steel hopper car?
I admit that it's NOT prototypical. The real Colorado & Southern never had any narrow gauge steel hoppers, and the C&S logo lingered long on the narrow gauge after it disappeared on the C&S's standard gauge lines because the parent-company CB&Q did not want to be associated with the anachronistic narrow--gauge trains. But it could have happened, at least if the C&S narrow gauge lingered a few more years, and certainly would stir up conversation.
Dear Mr. Lee,
That's why we make painted, unlettered cars!
Have fun!
