The Semmering railway (German: Semmeringbahn) in Austria, which starts at Gloggnitz and leads over the Semmering to Mxc3xbcrzzuschlag, was the first mountain railway in Europe built with a standard gauge track.
It is commonly referred to as the world's first true mountain railway, given the very difficult terrain and the considerable altitude difference that was mastered during its construction.
Set against a spectacular mountain landscape, the railway line remains in use today thanks to the quality of its tunnels, viaducts, and other works, and has led to the construction of many recreational buildings along its tracks.
