CASE: Medium and Widespread failure (Münchenstein rail disaster). The case study is for medium and widespread involves the event that occurred in the year1891 and previously, there were more than thousand’s deaths due to bridge failures and railaccidents (New York Times, 2017). BackgroundIn the year 1891, among the worst accidents happened in the history of the Switzerland,Münchenstein rail disaster. It was 14:15, the train left the Basel railway station and was movingtowards the Delémont. The crowded passenger train, took more than 70 lives and hundreds of theinjured people. Due to the poor construction of the bridge across the river Birs the train fellthrough a girder bridge. The bridge was constructed by the Eiffel's engineering company whohas constructed the Eiffel Tower in 1889 (Hahn, 2016). They have previously built many bridgesand flyovers in France. The size of the bridge was around 42 meters, built in the year 1975 andwas above 5 m of the river. Due to the heavy rainfall and serious local floods the bridge gotdamaged and was repaired. As it lies on the 4 piers, after the serious damage of the abutments itwas left on the three. All the structure requires proper base in order to stand same happened withthis too, as the abutments was destroyed, the 3 pillars were unable to support the loads exerted bythe moving overloaded trains. As a result, there were serious cracks that were replaced by theengineers. In 1890’s locomotives were getting popular so strengthening was provided to thebridge. The disaster took place as the driver of the train has applied the brakes before and at thebridge as stated by the eyewitnesses. The train too had load of itself, the passengers, carriages, apostal-carriage, express-carriage and two further passenger-carriages. They all collectively fall inthe river. Due to the disaster there were more than 73 deaths and 171 people seriously injured. Itwas one of the serious cases as the carelessness in the Engineering field had led to death ofinnocent people (PERESSUT, 2014). The fall of the train through the centre of the bridge wasonly as there was no assessment done earlier. Moreover, there are many cases where bridgefailure had caused many casualties. It was the first of such cases that happened in theSwitzerland. Risk IdentificationThe subsequent inquiry was developed to identify the main cause behind the failure. They foundthat the quality of the ironwork and the design was not the standards and there was damage due1
