Does the statement, "We've always done it that way" ring any bells...?

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 English expatriates built the US Railroads.

Why did the English 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 have that particular odd wheel spacing? Well, if
they tried to use any other spacing, the wagon wheels would break on some of
the old, long distance roads in England, because that's the spacing of the
wheel ruts.

So who built those old rutted roads? Imperial Rome built the first long
distance roads in Europe (and England) for their legions. The roads have
been used ever since.

And the ruts in the roads? Roman war chariots formed the initial ruts,
which everyone else had to match for fear of destroying their wagon wheels.
Since the chariots were made for Imperial Rome, they were all alike in the
matter of wheel spacing.

The United States standard railroad gauge of 4 feet, 8.5 inches is derived
from the original specifications for an Imperial Roman war chariot. And
bureaucracies live forever.

So the next time you are handed a spec and told we have always done it that
way and wonder what horse's ass came up with that, you may be exactly right,
because the Imperial Roman war chariots were made just wide enough to
accommodate the back ends of two war horses.

Now the twist to the story...

When you see a space shuttle sitting on its launch pad, there are two big
booster rockets attached to the sides of the main fuel tank. These are
solid rocket boosters, or SRBs. The SRBs are made by Thiokol at their
factory in Utah. The engineers who designed the SRBs would have preferred
to make them a bit fatter, but the SRBs had to be shipped by train from the
factory to the launch site.

The railroad line from the factory happens to run through a tunnel in the
mountains. The SRBs had to fit through that tunnel. The tunnel is slightly
wider than the railroad track, and the railroad track, as you now know, is
about as wide as two horses' behinds.

So, a major space shuttle design feature of what is arguably the world’s most
advanced transportation system was determined over two thousand years ago by
the width of a horse's ass!

And you thought being a horse's ass wasn't important!!
