Countdown to Powers of Ten Day

Here we have another GP38 from my fleet. This particular version is in “O” scale or 1/48 of full size. On the scale still basically at 10-2 but almost twice the size of HO and four times the size of the N scale seen earlier. This particular model is made more for the play market hence the large space between the trucks and the body to allow for unrealistic swings of the trucks on sharp curves. Also the quite hefty handrails that are totally out of proportion for the size but neccesary to survive in the toy world.
Many details are reduced or eliminated in this model but the makers have taken advantage of the large body to include several lights – note the two red and two white lights just above the number boards. When properly set up, the red lights show on this end when the model is running forward and the white lights show when running in reverse. This is the back of the locomotive, but for this type of machine forward and reverse are equal in speed and power. That is why you see locomotives coupled together in 10-0 world without regard to direction. If you look closely at the frame on a 10-0 locomotive you will see a small “F” stenciled on the corner of the frame. That is the only way to know the “Front” or “Forward” direction of the unit.
Here is another GP38 From my fleet. As the scale gets smaller – still in the range of 10-2 but now 160 th real size a problem of scale starts to really show up. Look at the size of the handrails! On a full scale version those handrails would be about 6″ across clearly a problem for the scale model. Going back to the full scale 10-0 version at 250,000 lbs this version should still weigh in at a staggering 1,500 LBS!!! Personally I am glad it only weighs in at a total of 4 ounces.
While many of the other measurements are close approximations of the full size item – weight has clearly suffered in the 10-2 version.
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.
Here is railroading at 10-0. This is an example of a GP38 locomotive – some basic facts:
4 axles on the rails
16 clinders in the prime mover (railroad speak for the diesel engine)
706 Examples built by General Electric Locomotive Division
58,000 lbs of pulling force
250,000 lbs average unit weight.
A massive machine with one purpose – pulling freight all day, every day.
How do you create a scale model of something this huge?
So here is my world and where my concentration on the Powers will fall – while not exact in the scale of things, I spend a lot of time thinking about and working in about 10-2of the real world. In my hobby world a 6 foot tall human is about 1.8cm.
Part of what we do is making things small look as real as possible – what do you think about the photo? Did you stop and wonder for a second or two if it was the real thing?
My plan is to show some of the tricks and techniques we use to fool the eye and create a world that is close to 10-2.
