That's why I said in the US, we do indeed who invented railways, we are forever thankful.
But what is that sign?

I thought that was Whitworth.Wasn't it the Romans?No, they just invented standard gauge wheel ruts. The rails came later.

Nope, he developed the hexagon-headed bolt and wrench and thread system that bears his name. AND the hexagonal bullet that was fired with astonishing accuracy from the hexagonally-bored rifle that also bears his name - much-used by the Confederacy during the WoNA [ask General John Sedgwick]. Artillery also got his attention and his factory produced a range of hexagonal-bore field guns.
Anyhow - the average Roman wagon was designed to be hauled by two horses/donkeys/oxen/other BOBs - this made the width of the axles pretty much a standard measurement throughout the Roman Empire. The wheels were therefore more or less that same distance apart, as you can see by the still-present wheel ruts in Pompeii and Herculaneum. That distance is ~4ft 8 1/2"...
Sound familiar?

So the Romans invented horses..
Two horses need about 4' 81/2" between the wheels, so they don't trip / break anything.
When they left (the Romans, not the horses!), it ain't broke, so we left it?
Yeah but, someone did try to fix it!
IKB!

Interesting, nice to have that gradient information right there... railway gradient posts, what a concept.

Some railway companies used the word level instead of the infinity sign
Perhaps that sign came from Buzz Lightyear's railway
