In Biaschina the engineers who designed the line had to
resort to the method of the spiral ramps to overcome a
height difference of over 200m. In the gorge there are two
almost overlapping spiral ramps. The railroad, for those
coming from the valley, crosses the river Ticino and enter into the gallery called "Travi" of 1547
m. At the exit of this gallery you can see below the tracks
just before getting paths in the second tunnel ramp called
"Pianotondo" of 1508 m. After the tunnel, there is the
imposing viaduct, also called "Pianotondo". For those who
keep the show from the valley can see three levels of
the railway. In the attached
slideshow you can see the
Cisalpino ETR470 from Milan, which leads north going up the
ramp, and going south down the goods train. The two trains pass at the
second level.
