To your point, a contributing factor here was the front train couldn't start due to either a minor or bogus "security" alarm. Whatever alarm that was, it wasn't worth triggering such a tragic accident.
To be fair the Spanish word for security is the same as the Spanish word for safety: seguridad. It could as easily be a ‘safety’ alarm and a mistranslation.
I do not Spanish to assert whether it is true, but it is often said about German and there it is not true. I think the issue, that it is often mixed in daily speech, but that's true for English as well.
