This is an article where I think Snopes does a really bad job. Pretty much every factual allegation in the original article is false, and to cap it all off, actually trying to track down the key assertion--the effect of rail transportation limitations [implied to be caused by history dating back to Roman times] on booster design--indicates to you that it had no relevance whatsoever. Snopes is accurate in that the track gauge being slightly less than 5' is somewhat correlated with the width of two horses. But the track gauge being slightly less than 5' isn't even relevant to the main claim!
