"Double" human error and a signaling failure: what could be behind the accident in Toledo

A collision between two trains in Toledo, Spain, resulted in over 30 fatalities, attributed to a signaling failure and human error. An Iryo train with 147 passengers was stationary due to a signaling malfunction when it was struck by a Renfe AVE train carrying 393 passengers at high speed. The malfunction involved a failure in the LZB signaling system, confirmed by Transport Minister Óscar Puente. Investigators suggest a 'double human error' occurred, as the ADIF controller allowed the Renfe train to depart despite the Iryo train being stopped nearby. Puente refrained from assigning blame but acknowledged the inexplicable nature of the situation. This incident marks the second major train accident in Spain this year, following a previous collision in January that resulted in 46 deaths.
