Homeostatic perpetuation

We can all appreciate that homeostatic forces are powerful dynamics in systems, from family to governments. Homeostatic force has at least two characteristics: (1) its force comes as a multigenerational tidal wave, and therefore difficult to resist, and (2) like a tidal wave, it is an unthinking force. Meaning, you can’t reason with it.

Culling through old files (yeah, still working on New Year’s Resolution no, 7) I came across the following from my friend Lewis (from 1996). I don’t know the source, it’s the kind of piece that gets passed around via e-mail. It’s a good example of homeostatic perpetuation through the path of least resistance: non-thinking, doing things a certain way because it’s the way it’s always been done.

How Military Specs Live Forever

The US Standard railroad gauge (distance between the rails) is 4 feet, 8.5 inches. That’s an exceedingly odd number. Why was that gauge used? Because that’s the way they built them in England, and the US railroads were built by English expatriates.

Why did the English people build them like that? Because the first rail lines were built by the same people who built the pre-railroad tramways, and that’s the gauge they used.

Why did “they” use that gauge then? Because the people who built the tramways used the same jigs and tools that they used for building wagons, which used that wheel spacing.

Okay! Why did the wagons use that odd wheel spacing? Well, if they tried to use any other spacing the wagons would break on some of the old, long distance roads, because that’s the spacing of the old wheel ruts.

So who built these old rutted roads? The first long distance roads in Europe were built by Imperial Rome for the benefit of their legions. The roads have been used ever since. And the ruts? The initial ruts, which everyone else had to match for fear of destroying their wagons, were first made by Roman war chariots. Since the chariots were made for or by
Imperial Rome, they were all alike in the matter of wheel spacing.

Thus, we have the answer to the original questions. The United States standard railroad gauge of 4 feet, 8.5 inches derives from the original specification (Military Spec) for an Imperial Roman army war chariot. MilSpecs and Bureaucracies live forever.

So, the next time you are handed a specification and wonder what horse’s ass came up with it, you may be exactly right. Because the Imperial Roman chariots were made to be just wide enough to accommodate the back-ends of two war horses.
