I've given up on trying to be disciplined and have decided to model all eras, scales and gauges. And all locales too. It's easier. Of course I'm just an armchair modeler in N, S, TT, G, No. 1, and so forth but that doesn't matter.
I do have a sweet pair of brass P48 ARA trucks that's begging for model to be kingpinned to. Perhaps a steam era 1937 box car might make an appearance at The 'Ville.
