How swiss railway companies premine:
Field landslides, debris flows or falls of stones can be dangerous for trains. Meanwhile, In Switzerland, railway companies have several strings to their bow to prevent these risks.
A railway accident in Baden-Wurtemberg in Germany cost three people and injured dozens, some of them seriously. Meanwhile, Strong rains and a landslide caused the train derail.

In Switzerland, the last serious rail accident caused by a landslide occurred eleven years ago. Meanwhile, A train from rhetorical railways derailed near Tiefencastel, in Graubünden, killing and injured.

Regularly controlled protection structures – How swiss railway companies premine
The example of the Lötschberg shows by what means we try to avoid mountain train accidents. The protection of railway lines against natural risks begins at altitude.
In Valais. with its high mountains and steep slopes, the maintenance of the protective forest-a natural barrier above the rail line-is the most important measure. But the forest is just one element of the concept of security.
“Immediately after the construction of the railroad. 110 years ago, we started to build protective structures on the Lötschberg,” said the Ferdi Pfammatter Public Media, forestry of the BLS railway company (Berne-Lötschberg-Simplon) how swiss railway companies premine for more than 20 years.
Among these protective structures, there are protection nets against stone falls. “But there can also be barriers or fences: these are relatively fine stacks, monitored by a fine electric wire.”
The surveillance cables must be maintained regularly to ensure their protection. The fine wires do not offer optimal protection against bad weather and rocks, says Ferdi Pfammatter.
Alarm system
If a network is damaged, the system automatically triggers an alarm. Everything that happens in the field reaches a few seconds later at the Spiez operations center. directed by Martin Wyss, responsible how swiss railway companies premine for the proper functioning of railway operations, which provides coordination in the event of an emergency.
The system alerts those concerned with the operations center. who act according to their role, he explains to SRF: “Deploy staff on site, interrupt rail traffic, make sure that the right people arrive in the right place and, above all, that nothing else happens,” he lists.
Each line relating to the competence of the company. including the basic tunnel of the Lötschberg, is monitored. Despite all technology, a residual risk remains. “The question is rather to know what how swiss railway companies premine measures can be taken to prevent such accidents,” explains Martin Wyss.
In the end, an in -depth understanding of the critical points of the layout is essential. “We know the critical points of the network mainly from experience,” explains Martin Wyss. Additionally, “Thanks to on -site inspections and daily interview, we then take the appropriate measures.”
