Nothing as awesome as what you guys have done; I guess I'll need some stock to run on 3 rail track to go behind my new loco.
I've had an old Athearn boxcar sitting around for years, so I slapped on a couple of Atlas/Roco trucks and now at least I have a full-size O scale car with big flanges:
Still have to add details, but it's a start.
Disclaimer: I am not responsible for the crappy glue job on those grab irons; this car came to me this way, I swear!
