On February 6th 2020 an unexpected water/mud inflow of initially more than 100 l/s occured in the 13 years old L?tschberg-Basetunnel. Such a water inflow in a tunnel sealed with a high tech sealing and drainage system was not expected by anybody. A passenger train of SBB was affected. It passed the water/mud zone and arrived at the southern portal, dirty but safe with good luck.
On March 14th a second inrush occurred. The traffic had to be stopped once more.
10 weeks after the first event the research into the causes has still no priority, as it was confirmed on April 22, 2020. This does not fit to the basic principles of risk management. Each risk has a root cause. The root causes of occurred risk events have to be known in order to eliminate future similar risks. Risk management consists not only in mitigation measures but also in eliminating risks.
It is not understandable that Swiss Federal Transport Office does not insist in publishing the root cause of the risks events in the L?tschberg-Basetunnel for the benefit of other actual projects under construction and for future projects of long and deep tunnels. Safety first must be guaranteed always. Railway systems are only safe when the basic principles of risk management are respected without compromise.
An article in the NZZ of April 22 also deals with this topic.

4 年Fully agree, a good post, Heinz! Obviously the mills of Federal Transport Office run very slowly. What and more important when will change s.th.? When a train with hundred of passengers will be affected tremendously without having luck like the mentioned one? Hopefully not!
