(1,000 apologies for bombarding the SI-LIST with this but I couldn't
resist. It is often strange/funny where "standards" come from!)

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

I won't bore you (and use up BW) with the long story but suffice it to say
that it is about the width of 2 horses' behinds....
