ZURICH – Swiss technology is due to hit new heights on Friday when the world’s steepest funicular line opens at one of its Alpine resorts.

Swiss President Doris Leuthard will officially open the $52.6 million project running from Schywz to the mountain village of Stoos, which lies 4,300 feet above sea level in central Switzerland.

The barrel-shaped carriages adjust their floors so passengers can still stand upright even as they climb towards the Alpine plateau at inclines of up to 110 percent.

The train, which will go into public service on Sunday, will climb 2,437 feet over a span of 5,702 feet, at speeds of up 32 feet per second.

“After 14 years of planning and building, everyone is very proud of this train,” said Ivan Steiner, spokesman for the railway.
