I’ve been looking for streamlined MTH 18” passenger cars for my D&H Alcos for a week or so. While I was at it, I thought I would look for some streamlined Pennsy cars for my GG1s to pull. I have a dozen 18” PRR Madisons, but think that streamlined cars would look better with the GG1s. It took only a few days to find a 5 car PRR set from 2004 and a matching 2 car set from 2006 (both NIB and from different sellers). I will eventually find a D&H set, but it will probably take a lot longer. On the big auctions site there is currently over 100 offerings for PRR MTH passenger cars, but only about 6 for D&H.
