Was standard railroad gauge determined ...

I generally agree with Cecil on this – people doing similar tasks (hauling human-sized cargo on wheeled vehicles) are likely to come up with similar sizes – and this anecdote makes a big deal about this obvious fact.

But I have another fact to add to this.

The “Roman war-horses” would have looked like ponies alongside the English draft horses used to pull wagons. The breeding of horses improved greatly during the intervening 1500-2000 years, and English Draft breeds are quite literally twice the size of Roman horses.

So saying “the railroad gauge is set to match the width of 2 horses’ asses” only makes sense if the horses are the same size. And they aren’t.

Linky linky.

Was standard railroad gauge (4’8½") determined by Roman chariot ruts?

As Joey G is trying to tell you oh-so-subtly, it’s a pretty good idea to include a link in the OP to the subject we are about to discuss. That way, someone doesn’t have to say, “WTF ya talkin’ 'bout, newbie?” :slight_smile: :slight_smile:

That said, I have nothing more to add to this discussion. Carry on.
