Disaster Brétigny: SNCF questions the rigor of … – The Obs

Paris (AFP) – The SNCF doubts the seriousness of the metallurgical assessment carried out following the rail disaster Brétigny-sur-Orge, and asked the investigating judges supplements expertise, citing two hypotheses . bad parts placed under seal or voluntary unbolting

In this application, submitted on 19 January in justice and of which AFP obtained a copy, SNCF regrets that “merely to explain that the bolt heads have broken by fatigue, experts have provided no explanation for the incomprehensible lack of the nuts on the screws. Yet the accidental unscrewing a nut oxidized technically highly unlikely. “

The railway company believes that “there can be only two assumptions: either placed under seal parts are not good, or the nuts were loosened by a deliberate action”

Yet. “the evidence we have today, our conviction is that the voluntary act is not plausible,” he told AFP a spokesman of the SNCF. This means that for the SNCF are not good bolts that have been sealed.

The derailment of a train in Brétigny-sur-Orge station (Essonne) was caused by the flipping a splint, a kind of metal clip that holds 12 pounds two consecutive rails.

Of the four bolts that fixed the rail joint bar, three were absent July 12, 2013, according to the findings of judicial experts in their report published a year after the accident. The experts had also severely questioned maintenance rules. What the SNCF “strongly disputes” in this report

-. Expertise lack of seriousness’ –

In its request for additional expertise, SNCF demonstrates, step by step, how this metallurgical expertise, begun in March 2014 – eight months after the accident. – and made in September 2014, lack, in his view, serious, and includes “errors”

In particular criticism the time between the accident and the beginning of the analysis, a soiled and damaged during the accident place, with parts that have been damaged then necessarily, and referrals withdrawn abruptly. SNCF also judge on the bolts, that there was “no scientific analysis.”

According to the SNCF, “contrary to the claims of the experts, the bolts of the bolt in question, were present on the splint, shortly before the accident “and” rupture did not occur at the end of a long process of fatigue, which escaped the vigilance of agents during inspection tours. ”

The derailment Paris-Limoges in Brétigny-sur-Orge station killed seven people. Réseau Ferré de France (RFF) and SNCF have been indicted in Evry for homicide and unintentional injuries. In total some 4,000 pages of expert were made.

“The criminal investigation, which is to enable the demonstration of the truth, (…) must necessarily proceed by realization of a number of complementary expertise work, “says the train still in its application to justice.

She wants the experts” complete their work by asking them to answer a series of questions that appear to him to this day still critical to determining the cause of the accident. “
