It is not a whole number in either meters or feet…how did the engineers come up with this number.. what made this the standard in this standard gauge.
Let’s examine the reasons:
– Because that’s what it is in UK, who were the original Pioneer of the railways. Ok. But why?
– Because that was the distance of the tram in Pre- rail road era. Ok. But why?
Apparently this is the average distance between the two wheels of a horse pulled carriage of the yester years. The engineers who were developing the rail system, for lack of any reference points took this to be the standard.
And do you know why a two wheel horse pulled carriage had this really odd wheel distance?
