[#oops]OK so I can’t type. What else is new?
The PRR had 135 GG1 engines. Two were painted silver for the Congressional limiteds but there was sufficient grease and filth that they were quickly repainted as the silver did not hold up. Five were then painted tuscan red for the two Congressional limiteds and the two senators with one spare.
The Frisco (SLSF) used black and yellow for their freight units, and a bright red color on their passenger E units.
Perhaps stretching the point a little, but there were some railroadsthat in the 1960s began painting their diesels in a simplified paint scheme, eliminating one or more colors or stripes or something, but kept the passenger cars in their original scheme.
Great Northern for example simplified the Pullman green / Omaha orange scheme and eliminated the yellow stripes in between, in their diesel engine scheme, but never changed the passenger cars (well, until they went to Big Sky Blue in the later 1960s).
The ORIGINAL Norfolk & Western paint scheme for freight and passengers was nearly identical but was basic black for freight and Tuscan Red for passnger units. All passenger units were GP-9’s until they leased some RF&P and ACL E-units in 1958. These units remained in original colors but had N&W on the sides replacing the owner’s names.
Illinois Central also kept the chocolate and orange for passenger diesels/cars until Amtrak took over. That was several years into their orange and white freight paint scheme era, which began in 1966.
Add Cotton Belt with four daylight passenger diesels. The other five passenger RS-3s were in black widow paint. Ed in Kentucky
