A broken joint on the rails has been identified as a key factor in the recent high-speed train derailment in Spain, which claimed at least 39 lives. The accident, which occurred near Adamuz in the southern province of Cordoba, involved a train operated by Iryo, a private rail company. Experts revealed that the faulty joint, known as a fishplate, had been present for some time, creating a gap that widened as trains passed over it. This discovery has led to a deeper investigation into the causes of the disaster. The Spanish Prime Minister, Pedro Sanchez, and Transport Minister, Oscar Puente, visited the crash site, with Sanchez canceling his trip to the World Economic Forum in Davos due to the tragedy. The train, a Frecciarossa 1000 model, was less than four years old and had undergone a recent renovation. The manufacturer, Hitachi Rail, conducted a routine inspection on January 15, finding no anomalies. However, a Spanish train drivers' union had previously warned the rail operator, ADIF, about severe wear and tear on high-speed tracks, including a fatal crash site where two trains collided. This incident highlights the importance of regular maintenance and the need for proactive measures to prevent such disasters.
