Glenn Fresch postedIf your going to nitpick most German narrow gauge that is not metre gauge is 750mm not 760mm , 760mm is the gauge mostly found in Austria.
Any reason for the difference?
Correct me if I'm mistaken, but I think the gauge differences were a holdover from the old Austro-Hungarian Empire, which included the Balkan states. Having a common gauge that wasn't seen outside your borders may have been a strategic thing too, like the narrow-gauge American trolley lines trying to keep the standard gauge railroads off the streets.
