Maybe, but the sentence you are relying on for the number isn’t scoped to the south but the entire continent.

“By June 1886, all major railroads in North America, an estimated 11,500 miles (18,500 km), were using approximately the same gauge“

It is a little unsatisfying that it doesn’t seem to say how much was moved.
