They're easy to distinguish from SD40/-2s, but are there any external differences from stock SD50s?
Fan of late and early Conrail... also 40s-50s PRR, 70s ATSF, BN and SP, 70s-80s eastern CN, pre-merger-era UP, heavy electric operations in general, dieselized narrow gauge, era 3/4 DB and DR, EFVM and Brazilian railroads in general... too many to list!
