I think it’s reasonable to argue that the SD40-2 was the defining example of 2nd generation diesel locomotives in North America. They were purchased in huge numbers by most Class 1 railroads and have developed a reputation for reliability over decades of operation. Today they’re less common on Class 1’s, but many are being rebuilt to extend their lives and quite a few are well into second careers on regional and short lines. It has therefore been rather unfortunate that HO scale modelers have never had a really good plastic model of the SD40-2 (I’d argue that there’s never been a really good brass model either, because, well. Brass.) Many companies have made an attempt at the SD40-2, but most have gotten stuff wrong (Athearn, Intermountain) and no one has made a stab at the huge amount of variations that occurred over the twelve year production run (Kato). Athearn could and should have put an SD40-2 in their Genesis line to go along with the GP models they’ve been releasing but they never did.
Therefore, it was no small thing when I cam home from work about a year ago to find a box from Scale Trains sitting on the stoop. Inside, I hoped, was the SD40-2 so many of us have been waiting for.
