This steep Swiss mountain side is not without its challenges to construct a tunnel with 110% radiant has really been done before.

If the breathtaking climb itself doesn't leave, you wake up the nays.

Each of the carriages can carry 34 people at a speed of 10 meters per second, meaning the climb or descent last no longer than four minutes.

Up here, 1300 meters above sea level is not a view for the faint hearted and transporting people up.

This steep Swiss mountain side is not without its challenges.

Two years behind schedule, it's taken 14 years of building on with a price tag of $53 million.

But the Swiss are convinced their new funicular on the world's steepest line is worth it.

The style I turned that same cents to construct a turner with 100 and 10% radiant has rarely been done before.

All the workers have to secure themselves.

Sometimes they have to work hanging in the ropes.

We have to be very careful with the material If you drop something, it falls all the way down on what's even more dangerous.

Each of the carriages can carry 34 people at a speed of 10 meters per second, meaning the climb or descent last no longer than four minutes.

The line replaces an old funicular that had been operating between the valley town of Schwitz to the mountain village of Stews.

Since 1933 the new space age looking carriages have been held an engineering success.
