Simplon Tunnel opened

In 1906, the Simplon Tunnel was officially opened as the world's longest railroad tunnel. Cutting through the Alps between Italy and Switzerland, it was officially opened by the King of Italy and the president of the Swiss Republic. The construction of the 12-mile Simplon Tunnel, one of the world's longest rail tunnels was undertaken in the 1890s by Alfred Brandt, head of a German engineering firm, and inventor of an efficient rock drill. The total length of the tunnel is 64,972 feet cut through the solid rock of the Simplon Mountain between the Rhone and the Diveria valley. As a direct route under the mountain, it considerably shortened the surface distance for an important European trade route between Brig, Switzerland and Iselle, Italy.
