Seaboard Air Line had some nice and not so nice paint jobs, but they did paint their diesels differently for the service they were meant.
Freight diesels were painted (more or less) Pullman Green:
and later in the "Jolly Green Giant" Green:
Passenger Diesels were painted (1st) in their Citrus Scheme:
and later in their Mint Green scheme:
And of course their switchers were painted red and black:
There were some experimental paint schemes, but these were the ones that stood the test of time.
What other RRS did this???
