In 1983 and 1984, Don Strack spent some productive time with a 100' measuring tape recording some major dimensions on five SD40-2s and SD40T-2s.
The project came to an end when he realized that the bolster centerlines of the then-new Athearn model were short, thereby making accurate frame measurements a meaningless point.
