Madrid: Spain is continuing its investigation into the train derailment. Spanish authorities are continuing their investigation into the cause of a high-speed train derailment on Sunday evening, as the latest death toll rises to at least 40.

According to Thai News Agency, a team of experts has traveled to the site of the high-speed train derailment near the southern city of Adamuz. Initial investigations have revealed that a damaged joint in the railway tracks created a gap, which widened as the train continued to travel. Sources indicate that this damaged joint may be a key factor in determining the cause of the accident. The head of Spain's train accident investigation committee stated on television that a significant factor in train derailments is often the mechanical interaction between the tracks and the train, which the committee is currently investigating.

Meanwhile, authorities are rushing to identify the victims. Police have opened an office in Cordoba province to collect DNA samples from relatives for comparison to identify the deceased. The latest death toll has risen to at least 40, while 43 missing person reports have been filed at police stations in several cities. Additionally, 41 people are being treated in hospitals with injuries, 12 of whom are in intensive care.

The train derailment occurred late Sunday. A high-speed train operated by Iryo, traveling from Malaga to Madrid, went off the tracks and crossed a parallel railway line. A train operated by Alvia, traveling in the opposite direction from Madrid to Huelva, collided head-on, causing the Iryo train to derail as well. Latest reports indicate that over 500 people were on board both trains. The Spanish government has declared three days of mourning, beginning today. Flags are flown at half-mast in Spain and at the European Parliament in Brussels, Belgium.
