The United States standard railroad gauge of derives from the original specification for an Imperial Roman war chariot. 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 war chariots were made just wide enough to accommodate the back ends of two war horses. The railroad line from the factory had to run through a tunnel in the mountains. The tunnel is slightly wider than the railroad track, and the railroad track is about as wide as two horses’ behinds.

Sperm swim, whether you’re straddling your partner, standing up, or doing somersaults.

They can live inside the body for up to about five days. Coitus interruptus is when your partner pulls out of the vagina before ejaculation.

So, the major 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!

This item about the gauge of modern American railroads having been slavishly copied from the measurements of ancient Roman war chariots is a concept we’ve seen expressed well over a century ago, as exemplified by this nugget from a 1905 issue of Popular Mechanics: came to be adopted as our standard railway gauge.

The technology evolved quickly in the 1840s, however, and the United States played an important role in that evolution.”) Similar thinking occurred in Britain.

Historian James Crow, writing about Housesteads, the The wheel rut and gate stop in the north passage are well preserved, and a number of reused stone blocks formed part of the latest surface to survive.

The eventual standardization of railroad gauge in the U. was due far less to a slavish devotion to a gauge inherited from England than to the simple fact that the North won the Civil War and, in the process, rebuilt much of the Southern railway system to match its own: [I]n the occupied South the government went into the railroad business on a large scale. As for the Space Shuttle addendum to this piece, when Thiokol was building the solid rocket boosters (SRB) for the space shuttle, they had to keep shipping considerations in mind, but they didn’t have to alter their design because any particular tunnel that lay between their plant and the Florida launch site wasn’t large enough. Army’s Rail Transport in a Theater of Operations document, for example, makes it fairly clear that one would be hard-pressed to find railroad equipment anywhere only “slightly wider” than of a horse’s ass (literally, the width of that particular portion of equine anatomy).

In February 1862 [Secretary of War] Stanton established the U. Military Rail Roads and appointed Daniel Mc Callum superintendent. Railroads don’t run through tunnels only “slightly wider than the railroad track” unless every one of their engines and all their rolling stock are also only “slightly wider than the railroad track,” and unless all tunnels encompass only a single set of tracks. People find this notion amusing, feeding the story’s popularity as charmed readers continue to pass it along to others in a cascade of forwards.

The gauge between the ruts is very similar to that adopted by George Stephenson for the Stockton to Darlington railway in 1837, and a ‘Wall myth’ developed that he took this gauge from the newly excavated east gate.
