The Schwarzwaldbahn, or Black Forest Railway, 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 railways,
including the Bernina Line and the Gotthard Pass.
Running through some truly spectacular scenery, the Schwarzwaldbahn Railway has remained popular with both the Black Forest locals and tourists alike, ever since its opening.
