As an illustration, this month I was fortunate to be part of several collaborations with the local group of layout owners. First off was an evening weathering with David Olesen, whose 1986 CSX layout following the former C&O main line over Allegheny Summit is coming along. He asked to see how I weather locomotives, and brought a few of his new purchases to be our subjects.
Alongside David, I weathered my recent purchase of a CN C40-8M, a fabulous model by Rapido Trains. Rapido, in my view, is really coming on strong with excellent models of critical locomotives and cars that modelers have been asking about for many years.
I have a feeling you won't be disappointed!
