Years ago I used to enjoy detailing, painting, and decorating my HO scale steam locos. I couldn't afford brass and it was a cost effective way to get a reasonably detailed loco (this was before the explosion of highly detailed plastic steam in HO), or a model with the details I wanted (like Elesco FW heaters). Besides, these projects were a gratifying part of the hobby for me.
I find I am now in a similar situation with O scale. Lionel and MTH Premiere steamers are too pricey for me. MTH RK steam fits both my budget and Hi-Rail modelling philosophy. However, I'd like to add details to a couple of my locomotives. That process would require a repaint and of course decals. While I can find paint, and I assume Precision Scale parts are still available, finding decals is problematic (and I'm not looking for oddball stuff - PRR and NYC for me). That decals are so hard to find in O-Scale raises the question - is anyone else out there doing loco detail projects? Are our models so prized as they come out of the box that we don't dare alter them less they lose their "value?" Is this aspect of our hobby dead?
