Reply to comment by villevalla in TIL that the southern United States converted all 11,500+ miles of its railroads from broad gauge (5 ft/1.524 m) to nearly-standard gauge (4 ft 9 in/1.448 m) in just 36 hours, starting on May 31, 1886 by 1859

For those examples sure, there wouldn't be that much direct savings. But if you pick countries that actually have a land border instead of purposefully stupid examples then it facilitates rail transit between those countries a lot more easily.
