Has anyone made them in O gauge? Like this:
I bought a single MTH RailKing one yesterday and like it behind my GP38-2. I have 2 more of these locomotives, and want to do a long unitish like train with the 3 locomotives and a long string of the spline TTUX piggybacks I already have and spline intermodals in either 3 or 5 unit sets along with some single units sprinkled in. But I can't seem to find any info on them being made when I thought I had for sure seen them in a catalog a few years ago.
