The U.S. 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 designed the U.S. 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 jig and tools that they had used for building wagons, which used that wheel spacing.



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 (including England ) for their legions. Those 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.

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



In other words, bureaucracies live forever. So the next time you are handed a specification, procedure, or process, and wonder, 'What horse's ass came up with this?', you may be exactly right.

Imperial Roman army chariots were made just wide enough to accommodate the rear ends of two war horses.



Now, the twist to the story:



When you see a Space Shuttle sitting on its launch pad, you will notice that 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 larger, 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, and 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!



Now you know, Horses' Asses control almost everything...



Explains a whole lot of stuff, doesn't it?
 
How true, How true; :shock: :shock:
What's really a shame is that the same term can be used to describe MOST of our politicians !!

:roll: :roll: :roll: :roll:

ps: STOLEN to be forwarded to my email list for their edification !!
 
Quite a lot of current standards were developed the same way. Body sections for 747's, etc. are also delivered by rail to the Evt factory, so the same limitations apply.

That distance is face to face of the rail balls. I nearly messed up once setting up a hole pattern in wide flange beams using the more familiar (to me) center-to-center distance. Stands to reason, that's the gauge between the flanges of the wheels.

Reminds me of an old joke: :mrgreen:
All the organs of the body were having a meeting, trying to decide who was the one in charge.
"I should be in charge, "said the brain, "because I run all the body's systems...without me nothing would happen".
"No, I should be in charge" said the blood, "I circulate oxygen all over, ...without me you'd all waste away."
"No, I should be in charge, " said the stomach," I process food and give all of you energy."
"No, I should be in charge" said the legs, "because I carry the body wherever it needs to go."
"No, I should be in charge" said the eyes, "I allow the body to see everything."
"No, I should be in charge, "said the rectum, "because I'm responsible for waste removal"
All of the other body parts laughed at the rectum and insulted him, so in a huff, he shut down tight.
Within a few days, the brain had a terrible headache, the stomach was bloated, the legs were wobbly, the eyes were watery and the blood was toxic. They all decided that the rectum should be the boss.
The Moral of the story?
The Rosie O'Donnel is usually in charge.

Strange note:
When I typed this into the message body, the last line was "The a**hole is usually in charge." Then in the Preview it had changed to: The Rosie O'Donnell is usually in charge." Talk about auto-correct mode. I'm wondering what will happen when I hit 'Submit.'
 
jlmtr: It is not auto correct. This board tries to stay family friendly. If you type a word that is considered vulgar or socially unacceptable it will correct it for you at no charge. Also we try not to use the misspellings to bypass the filter. It's just being considerate of others. Plus most of us can figure out the initial meaning.

This humorous nugget has been around for a long time. It's not quite true. Snopes points out that one of the problems for the Confederate states was the existence of three rail gauges at the time of the Civil War. If Roman chariots determined rail gauge, we wouldn't see the variety that has existed across Europe.

AND the replacement word is FAR more offensive.

Now that's funny...But true :shock:

Thank you for clarifying that for me. I will strive not to use this type wording in the future. I do apologize to anyone I may have offended.

Howdy, I was not offended. Just explaining what happened.

I am ashamed that with our country's amazing engineering & manufacturing capabilities, that we do not have the most modern, high speed & fuel efficient passenger rail system and a dedicated Magnetic Levitation heavy freight system, up and running. We have the technology, we just have lazy politicians and leaders with no vision of Just how good it could be.

Politicians have nothing to do with it. It's a matte of economics. The RAILROADS have to buy and install the equipment. That costs LOTS of money. That cost gets passed to the consumer.

As opposed to the trucking industry, which rides on highways supported by taxpayers. Not exactly an even playing field.
