Carter Pate,
 The SRBs had to fit through that tunnel. The tunnel is slightly
>> wider than the railroad track, and the railroad track is about as  wide as
>> two horses behinds. So, the major design feature of what is arguably  the
>> world's most advanced transportation system was determined by the width  of
>> a Horse's ass!

For documentation I think you should ask Jega Arulpragasam or The TVRM. I
use to play on The General as a child at L&N station. When it was taken by
Disney to refurbish, they had to alter the wheel width a little so it would
run on todays tracks. I belive narrow gage tracks were used in mining,
logging, and factories. In England they still call railroad cars, wagons
and we still use the word coach even on airplanes. Automobiles had to run
on wagon roads. Guess what, I measured my 18year old German car inside
wheel width and it is 4' 8.5". It is true about the ruts in the road. We
had to stay in the ruts of north Ga. roads when I was a child; if not you
were stuck. As a prospector at 14, I belive on Grassy MT, Ga (I played with
dynamite) the stage coach wheel ruts are still there in stone 4or5 inches
deep. Check out the Pompi(sp) stepping stone spacing. I would think that
spacing is not Roman but Syraian(sp) or older. I have 9 horses on my place.
I would be glad to measure them for you.
