Models of steam, diesel, and electric locomotives have been produced by numerous manufacturers over the years.
An early 1960s addition that didn’t last long in Athearn’s line was the four-axle GP30 diesel locomotive model.
Nearly every hobby manufacturer has marketed an F-unit, just as nearly every railroad rostered one. Pemco added to the HO F-unit world with its F9A in 1980.
Pemco’s only six-axle diesel locomotive model was this EMD SD35. In addition to a variety of U.S. railroad paint schemes, this model also came decorated for Canada’s Ontario Northland.
You’ll find reference by Pemco to its F40PH model as an “FP-40,” this four-axle 1970s EMD passenger diesel came in Amtrak and Burlington Northern.
The second plastic Alco Century 430 for the HO market came from Pemco in 1980.
The only first-generation EMD diesel in Atlas’ mid-1970s run of Roco-made HO models was this FP7.
A second GP38 diesel model came to Atlas’ line in 1977 and provided a low-nose prototype. This was the last new tooling effort from Roco to join Atlas’ line in the 1970s.
EMD’s 3,000-hp GP40 served as the prototype fourth Atlas HO-scale diesel locomotive model in 1976.
Atlas’ first four-axle diesel from its mid-1970s collection of Roco-made models was this high-hood GP38.
The second HO-scale diesel model from Atlas in the mid-1970s was the six-axle SD35 of 1975.
