Excellent job on the roof Ben..
Coach Joe According to a TIES article way back in the day regarding paint schemes for Southern steam freight locomotives, tender decks were painted red. I do not recall TIES information on passenger Locomotives but early photos taken by the press at a favorite railfan site on Erlanger Hill of CNO &TP passenger engines southbound out of Cincinnati indicated red tender decks. According to one rail writer back in the day, that is also the photo op site where a fresh Ps-4 from the builder heading up a consist appeared with a red cab roof and was photographed and published nationally, which caused the "red roof syndrome" applicable when producing HO & N gauge models of Southern passenger locomotives? According to the writer the Ps-4 roofs of the real engines were actually repainted when reaching the normal shop cycle. But most hobby-builders persisted with red and some still do. Southern Master Mechanics were known to have great latitude regarding the paint decoration and application of accessories on engines. An O-gauge friend from Birmingham once told me that he saw some Alabama Great Southern Division green passenger engines with flat black cab roofs.
