The Civil Guard of Spain has formally requested detailed information from the Railway Accident Investigation Commission (CIAF) concerning "inconsistencies" in the welding process linked to the recent train accident in Adamuz, which occurred on January 18. Specifically, they are looking into a section of track where a 1989 rail of a certain hardness was welded to a more recent rail manufactured in 2023, raising concerns about the quality and reliability of this connection, especially since it was carried out by a relatively inexperienced operator. The timing and conditions under which these welds were performed have come under scrutiny, as they may be critical to understanding the incident's causes.

The new details emerged following the submission of a second report to a court in Montoro, revealing that out of 19 train operators who passed through the area prior to the accident, only one reported feeling a "jolt" to their right side. This suggests that there was something unusual happening at that particular spot on the tracks, which warrants further investigation. The findings could have implications for safety practices in railway maintenance, as they highlight potential issues with welding standards and workforce training.

As the investigation unfolds, the Civil Guard aims to ensure accountability and safety within the rail industry. This accident not only raises questions about the specific incident but also about broader systemic issues in rail maintenance and safety protocols. The outcome of this inquiry could lead to changes in regulations and procedures to prevent such accidents in the future, emphasizing the necessity for thorough oversight in railway operations in Spain.
