The Schwarzwaldbahn, or Black Forest Railroad,
runs between Offenburg and Singen, at a distance of 90 miles. The
line was constructed over a challenging terrain between 1863 and
1873, and even today it is hailed as a feat of engineering. Having
to overcome a height difference of 650 metres in some places, this
was managed by creating a series of loops, tunnels and viaducts.
These would eventually provide the inspiration for later railroads,
including the Bernina Line and the Gotthard Pass.
Running through some truly spectacular scenery, the
Schwarzwaldbahn Railroad has remained popular with both the
Black Forest locals and tourists alike, ever since its opening.
