The Superga Rack Railway (or Sassi-Superga Railway) is a mountain railway line in the city of Turin in Italy. It connects the Turin suburb of Sassi to the basilica church of Superga at an altitude of 672m (2205ft). From here, high in the hills facing the city across the River Po, there is a splendid panorama of Turin against a backdrop of the snow-capped Alps.
The line was opened on the 27th April 1884 as a cable driven rack railway of the Agudio system. In this system a cable ran along the side of the track and passed around two large pulleys on the side of the cars, which in turn drove the cog wheels that propelled the train. After an accident, the line was converted to an conventional electric rack railway and re-opened on the 16th April 1935. Along the line the guides for the previous cables can still be found.
The line is 3.1km (1.9mi) long, is of standard gauge, and overcomes a difference in height of 419m (1375ft) with a maximum gradient of 20%. The line is electrified with an overhead line at 600 volts. Trains carry up to 220 passengers to the summit in approximately twenty minutes. Although it does not run in the street, the line and its cars have some of the characteristics of a tramway, and the line is often referred to thus.
