That's the Viaduct of Markersbach, in the mountains along the Czech border. It's special because cost-saving steel pylons are uncommon in Germany and much of Europe (usually more enduring masonry was used outright, or masonry replaced steel during the early state railway era and the post-WWII reconstructions), and this particular style has a US origin. Unfortunately, the line it is on sees no regular traffic since 1996, although it saw tourist trains from 2009.
