It starts at [[Gloggnitz]] and leads over the [[Semmering]] to [[Mürzzuschlag]]. It was the first mountain [[railway]] in Europe built with a [[standard gauge]] track. It is commonly called the world's first true mountain railway. This is because of the very difficult terrain and the large altitude difference. It is still fully functional as a part of the [[South railway (Austria)|South railway]]. The Semmering railway was built between 1848 and 1854. There were about 20,000 workers. The director was [[Carl von Ghega]]. There are 14 [[tunnel]]s, 16 [[viaduct]]s and over 100 curved stone bridges as well as 11 small iron bridges. In 1998 the Semmering railway was added to the list of the UNESCO [[World Heritage]] sites. {{Coord|47.643|N|15.831|E|display=title|source
