The Semmering Railway, is approximately forty-one miles longwhich starts in Gloggnitz and ends in Murzzuschlag. It's considered to be one of the greatest feats of engineering, due to the height of the tunnels and viaducts, which have been used up until now, quite spectacular considering the tracks are over one hundreed years old. This great man made work of art is part of a beautiful landscape, in addition to many beautiful buildings along its route. All these elements come together and contribute to the beauty of this building. This construction is made up of fourteen tunnels and over a hundred curved stone bridges and eleven small iron bridges.
