Often said to be one of the first mountain railways in the
world, this awe-inspiring line also boasts the heady title of being
one of the few railways to hold a UNESCO World Heritage listing.
This title is for good reason, because the line, which has been
running since 1854, passes over and through some of the most
incredible scenery on the planet. Running over 41 kilometers from
Gloggnitz to Mürzzuschlag, the line winds through the verdant
beauty of the Semmering Pass, and passs over 16 viaducts, 110
bridges, and through 14 tunnels. Rather than disrupt the natural
beauty of the valley, the line was designed to work in harmony with
its surroundings, and therefore the views from the trains that run
along it are second to none. In 2012, a base tunnel through the
valley began construction, and it is expected to open in 2026, over
170 years after the line first opened.
