The Mont Cenis Pass Railway was to link the rail traffic across the Alps between France and Italy while the Fréjus Rail Tunnel was being built. A British development led by John Barraclough Fell, whose innovative three rail design revolutionized mountain railway design, the railway was tested on a brilliant summer morning in the mountains. The test was successful as the test run made the forty-eight miles from St Michel in France to Susa in Italy without a delay. The railway would open for business the following year but would cease operation in 1871 when the tunnel made the rail connection across the Alps permanent. (By John Osborne)
