Railroad Model Craftsman's September 1975 issue reviews
the Atlas SD35 beginning on that issue's page 76. Two pictures are included showing both sides of the Southern Pacific
SD35 example. The review metnions the model's incorrect "mirror-imaged" handrails that notch down on the engineer's side
of the unit's long hood for step that isn't there. The review also notes the steps coming from the cab are smooth
and lacking step details.
Around 1980, Pemco introduced its
SD35 model. The model, illustrated here in The Rock scheme, was produced in Hong Kong for Pemco and certainly appears
similar to the Atlas-Roco SD35 of 1975. You may find information regarding Pemco and its SD35, by clicking on the
image of the Rock Island example pictured above. Pemco's SD35 and the company
itself was short-lived, but a revised version of this tooling re-surfaced from IHC (International Hobby Corp.) in the
The 1980s saw Atlas offer new releases
with modification to the electrical wiring of the GP38 and GP40, but the SD35 built by Roco would not return to the Atlas
line following its 1970s appearance. Con-Cor obtained the tooling and produced new runs of the SD35 under its name
in the 1980s. Pictured is a Conrail SD35 from Con-Cor's offering.
