The first passenger locomotives for the Norfolk & Western Railroad were painted in a dark red paint scheme. With the Gold lettering and stripes they matched the equipment and showed the modern power off to the public.
Freight locomotives came in a more utilitarian Black scheme which more closely resembled the steam engines which they were displacing on the railroad.
The Norfolk & Western is well known to many because of the photography of O. Winston Link (OWL) who took numerous Black & White and color photos of the steam trains along the routes of the NW during the late 1950s with the cooperation of the railroad.
His work is featured at the O. Winston Link Museum in Roanoke's Terminal Station (http://www.linkmuseum.org/) which also has a number of his cameras and the large amount of flash equipment needed to make his images.
There are also may books highlighting his work including the newest Life Along the Line http://goo.gl/EzWGS
