Let's resume this thread with more pictures, photos, and information on the colorful passenger trains. This installation is the Atlantic Coast Line's "Champion" which operated between New York and Miami. Information for this post is supplied by "Streamliner Memories" on-line article that is very readable. There is also a recent thread going into great detail on consists, etc. For this thread, it's primarily about the photos and artwork of this train.
The purple/silver/yellow livery of the ACL champion E units is terrific.
Some explanation about several of the pictures. The postcard showing the FEC locomotives with the Champion is included because although the Champion operated from NY to Miami, ACL did not own trackage rights for the route. From Jacksonville, FL to Miami, the train was operated by FEC. North of Richmond the train was operated by RF&P and PRR.
The photo of the ACL E3A and the EMD FT is included because both were built in 1939.
The photo of the ACL E7's "under the wire" is included to show the locomotives leased to PRR when PRR was short locomotive power.
And the observation car photo is included because the Champion did not operate the more popular boat tail style observation cars; choosing, instead, to operate flat end observation cars which could be coupled mid-train.
Finally, the third from the last picture is a print depicting ACL E-7's done by Tony Howe.
Not being an ACL enthusiast myself, and having done minimal research for this post, any errors pointed out in the subsequent replies will be welcome.
