Here is a GP-38 from my personal fleet of locomotives. It is scaled at 1:87 or just about 10-2.
From careful measurements and comparison to the original I find this is a fairly accurate scale model with some noteable execptions.
A full size (10 -0 ) GP 38 weighs about 250,000 pounds, based on that measurement we would expect this example to weigh in the neighborhood of 2,800 pounds. Not even close and I am glad – so scale size does not come close to scale weight even with a solid metal frame. This particular version is modeled in one of the most popular scales for model railroading 1/87 of full size or HO scale. Other popular scales are “O”, “G” and “N”. More on those to come.
