Probably an oddity that I bring to the hobby (besides myself) is that I collect 40' box cars of different road names. I prefer the routine, mundane, and real looking box car reds and browns. I like to see different logos on each car as it passes but the relatively uniform color unites the train. Part of the reason I do this is because this is what I mostly saw growing up. The 40' cars looks best going round my 0-36 curves. And, as you can imagine, my favorite engine color is black.
I probably should get into weathering to complete the look but unless I can find a simple, easy, sure fired method, I am apprehensive. I have always preferred my motive power to look newish anyway.
What "oddity" do you bring to the hobby?
