Why We Do Things

More Thoughts  

The US Standard railroad gauge (distance between the rails) is 4 feet, 8.5inches. 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.





Thus, we have the answer to the original questions. The United States standard railroad gauge of 4 feet, 8.5 inches derived from the original specification for an Imperial Roman army war chariot.


Why do YOU do the things you do?

In addition:




Mike, this is not entirely true, for allowable widths and heights of railroad equipment (and thus their loads) have changed many times over the years. The latest major modification to rail equipment clearance was the development of double-stacked containers which forced the vertical clearances of many bridges and tunnels to be increased.

Historical Note:  When President Lincoln was assassinated, an especially palacial railroad car was chosen to transport his body from Washington to Illinois. However, this car was significantly wider than the standard equipment of the day, so out of respect for the dead president, the railroads on the route widened all the clearances to accommodate his car. (If I'm not mistaken, this was one of the first Pullman cars.) Soon after, this did become a "standard" car width and all railroads had to widen their right-of-ways.

By the way, the 4'-8.5" standard did not become standard for many decades after the widespread construction of railroads. Many of the early railroads had different gages that they used. It was only after the inefficiency and unsafe conditions created by these varied gages became too much that the American railroads agreed to one standard gage. As I recall, the decision (like virtually everything else) came down to, who had the most money, which was the Pennsylvania Railroad in those days.

So I think a far more accurate statement would be that a major design feature of what is arguably the world's most advanced transportation system was determined by golden rule (he with the most gold makes the rules.)

Finally, when the Czar of Russia was building railroads in his country, he specifically had the gage of Russian railroads build differently from that of the rest of Europe. His reasoning was that invading armies would not be able to use his own railroads in the event of an invasion. This odd gage turned out to be a major obstacle to the mobility of the German army during WWII. So, could it be said that a 20th Century German Army was defeated in part by Roman War Chariots?

In case you can't guess, I'm a Rail Fan.
