A former Erie Railroad executive and an efficient administrator, Mc Callum eventually presided over more than 2,000 miles of lines acquired, built, and maintained by the U. “Very interesting, educational, historical, completely true, and hysterical”? Let’s talk about sex — specifically, let’s talk about what people get wrong when it comes to sex.

This contrast illustrated another dimension of Union logistical superiority that helped the North eventually to prevail. Had the Civil War taken a different course, the eventual standard railroad gauge used throughout North America might well have been different than the current one.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.There is a common link, but it is more prosaic, and the ‘coincidence’ is explained by the fact that the dimension common to both was that of a cart axle pulled by two horses in harness (about 1.4m or It is rather inaccurate to claim that “US railroads were built by English expatriates,” but it is fair to say that since the English started to develop railroads slightly ahead of the Americans, some U. railroads used equipment purchased from English manufacturers, thus necessitating that the rails on which that equipment ran be the same size in both countries: in the United States.So, rather than going into excruciating detail about the history of transportation, we’ll simply note that roads are built to accommodate whatever uses them, and that for many centuries prior to the advent of railroads, what traveled on roads were mostly wheeled conveyances, pulled by beasts of burden (primarily horses), carrying passengers and goods.Physical conditions dictated some of the dimensions of those conveyances (such as the width of their axles) and largely ensured that they would fall within a fairly narrow range of variation: Horse-drawn vehicles, whether they were chariots or carts or carriages, all served similar functions, so practical considerations (e.g., the speed at which horses could travel, the amount of weight horses could pull, the number and arrangement of horses that could be controlled by a single driver) required that they be relatively similar in size as well.That may suffice as an explanation covering the specific combination of horse-drawn vehicles and roads, but what about vehicles that traveled on rails instead of roads (such as trolleys), or that weren’t pulled by horses (such as trains)?

Why should they be similar in size to their predecessors?

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.

There’s an interesting extension to the story about railroad gauges and horses’ behinds.

Here is a look into the corporate mind that is very interesting, educational, historical, completely true, and hysterical all at the same time: The US standard railroad gauge (width between the two rails) is That’s an exceedingly odd number. Because that’s the way they built them in England, and the US railroads were built by English expatriates. Because the first rail lines were built by the same people who built the tramways, and that’s the gauge they used. Because the people who built the tramways used the same jigs and tools that they used for building wagons which used that wheel spacing. Why did the wagons have that particular odd wheel spacing? Roman war chariots first formed the initial ruts, which everyone else had to match for fear of destroying their wagon wheels. When we see a Space Shuttle sitting on its launch pad, there are two big booster rockets attached to the sides of the main fuel tank. The SRBs are made by Thiokol at their factory in Utah.

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. The first long distance roads in Europe (and England) were built by Imperial Rome for their legions. Since the chariots were made for (or by) Imperial Rome, they were all alike in the matter of wheel spacing. The engineers who designed the SRBs might have preferred to make them a bit fatter, but the SRBs had to be shipped by train from the factory to the launch site.

Upon measuring the distance between them he found it to be in the neighborhood of and not doubting that the Romans had adopted this gauge only after much experience, he determined to use it as a standard in the construction of his railroads.
