The Minister of Transport and Sustainable Mobility, Óscar Puente, has published the Adif report on the Possible causes of the three recent train derailments in Atochawhich concludes that one was due to a broken needle, but in the other two there is no clear cause.
The report published this Saturday by the minister has been prepared by Adif in relation to the incidents that occurred in the Atocha-Recoletos tunnel consisting of the derailment of a Talgo on November 26 and two commuter trains that occurred on December 5 and 8.
Regarding the first of the derailments, that of a Talgo that traveled from Almería to Madrid-Chamartín, the report indicates that “it occurred due to broken needle of the crossing”, although the “ultimate causes are still under investigation.
Due to the limitations established by the incident, part of the circulation that did not normally do so began to enter track 5 of the Atocha station through detour 24. The Adif report highlights the circulation of commuter trains of the series 450 (known as “ships” or “double deckers”) for this point which they usually do not do.
On December 5, a first derailment of one of these “vessels” occurred at detour 24 and “There is no clear cause for it,” explains the report. In the early morning of December 8, the second derailment “very similar to the previous one, both by the type of train (series 450) and by the rest of the concurrent factors, such as location, typology and consequences.” Although, after carrying out seven tests with 450 and Civia trains on the same tracks, no issues.
The route layout design is correct
Adif concludes in its report that the second and third derailments occurred on detour 24 combined with series 450 trains (the “vessels”), in which, “in the absence of detailed data from the ongoing investigation, it could be have produced some unwanted effect due to the interaction of this type of vehicle with the specific route present on this route”.
He route layout design is “totally correct” and the reviews carried out “in the framework of maintenance are also appropriate.” The report adds that “the measures carried out gave a correct result, with nothing relevant being identified that could justify the derailments.”
However, it makes a series of recommendations for the circulation of trains in the area in view of the results of the seven tests carried out without incident.
