The Lasa Sloped Railway is rightly celebrated even today as a technical marvel. Even today, the custom-manufactured railway built for the special environment of the Stelvio National Park transports the heavy marble blocks over four sections almost automatically down into the valley.
The marble-transporting train has been operated in the same original state since 1930 and carries the marble from the marble quarry (2,200 m above sea level) to the valley. With the Lasa sloped railway, it is possible to transport a 40-ton load at a speed of 1m/sec in 16 minutes in to the valley. To date, this type of transport is the most environmentally-friendly method of transportation of marble thusfar. During the marble hikes, interested guests can also visit the unique inclined railway.
