Wonder what material is under yard tracks ? Looks like either tar paper or 1:1 scale shingle..Anyway, I like when MRRers are aware to not have main-line-shouldered-ballasted track in 'the bowl'.. Always sad when I see someone wasting time and, or $ to make bowl track sit at main-line elevation..Engine here may very well be on a main in or out of Dodge but still in yard limited throat track...At any rate, such a dignified loco it be.....M
