The investigation must clarify whether the security system failed due to network instability

The investigation into the Urda train accident suggests that electrical instability may have caused the safety system to disconnect. Engineer José Luis García Glugieri, involved in the LZB safety system programming, points to fluctuations in the electrical supply as a potential factor. He argues that the focus has been wrongly placed solely on the LZB system, which is just one part of a larger chain. The system has reportedly failed 170 times this year, raising concerns about its reliability. García Glugieri emphasizes that the electrical network's instability could lead to safety equipment disconnections, prompting trains to stop. He believes that recent increases in photovoltaic energy may have contributed to these issues, as the system has functioned well for 30 years prior to these incidents. The engineer also highlights that operational orders may have pressured train operators to continue despite system failures, potentially leading to the tragic accident.
