Southern Pacific SD40R

In early 1980, SP started to rebuild the 1966 and 1968 delivered 8400 series SD40's, the first SD40R released being 7300 in June 1980. The rebuilds continued through to August 1981, when 7385 was released.

Meanwhile back in late 1980, 7342 was released in an experimental paint scheme, based loosely on the Daylight scheme.

When it was first painted the paint separation between the orange and gray was actually down the center of the roof as above. This model appeared on eBay and generated a lot of discussion as to its accuracy. It is accurate and was not liked by Management, so was sent back to be repainted as the Tom Fassett model shown below with the gray roof on both sides. Anecdotally, it did operate in the above scheme before being repainted - again, hopefully photos may appear.
