An early 1960s addition that didn’t last long in Athearn’s line was the four-axle GP30 diesel locomotive model.
One of two EMD cowl-body six-axle diesels that joined Athearn’s line in the 1970s was the FP45.
A member of Athearn’s class of ’66, the SD45 diesel was a long-serving “Blue Box” favorite.
Part of Athearn’s big expansion of diesel locomotive models of 1966, the four-axle GP35 was a popular EMD prototype and HO-scale miniature.
Athearn adds its only Baldwin diesel prototype to its line in 1974 with the release of the S-12 switcher.
First introduced in 1970, Athearn adds Alco’s famous PA-1 and PB-1 passenger diesels to its HO-scale line.
At the same time Athearn introduced its Alco PA-1, a booster PB-1 arrives in the line in 1970.
Athearn’s steam generator-equipped SD40 model from 1966 replicated Electro-Motive Division’s SDP40 passenger diesel sold to Great Northern and NdeM, and included a number of fantasy road names as well.
Athearn introduced its 40-foot sliding door steel box car model in 1957, based on a “standard” design advanced by the Association of American Railroads.
Athearn’s biggest diesel of the blue box era was the D-truck monster DD40. Similar to the DD35A, Athearn decorated its DD40 for Union Pacific and provided the model with numbers matching the prototype DD35A.
