Train tracks. - Rail crash: production errors a contributing factor
An examination of the production procedure for concrete components uncovered chemical reactions responsible for the resulting damage.
According to a report released on Monday, these damages were part of a longer process and ultimately resulted in the structural collapse of pre-stressed concrete beams. The research also demonstrated that visual inspections during installation were insufficient to detect these damages. "The internal damages were much greater than what was visible from the exterior of the inspected pre-stressed concrete beams," the report says. "Furthermore, the cracking occurred in the region covered by gravel, rail, and small iron components."

The train crash in Bavaria, specifically in Garmisch-Partenkirchen, was caused by structural issues with the railroad. These issues were due in part to production errors, leading to chemical reactions that damaged concrete components. Despite visual inspections during installation, these damages went undetected, ultimately resulting in the collapse of pre-stressed concrete beams. The incident caused significant traffic disruptions in the area, including the city of Munich.
