F-units:
Several generations of F-unit are on display outside the roundhouse at Spencer. Historic F-unit demonstrator #103 is an example Electro-Motive's first F model, the FT. C&O 8016, on the other hand, can represent quite a few of the FT's successors - it has been identified as an F3, an F5, a re-built F3/F5, or an F7 by different groups (although I believe the most generally accepted designation given to it is F3). Lastly, Southern 6133, an FP7, hides in the background.
Not
just heritage schemes, not just commemorative schemes - this album is devoted to some of the world's most interesting paint schemes, past or present.
