Los 31 trenes de Cantabria y Asturias que no cabían por los túneles: una "falta de diligencia" que ya supera los 200 millones

In 2023, it was revealed that 31 trains commissioned for the Spanish regions of Cantabria and Asturias were designed with dimensions incompatible with the existing tunnel infrastructure. The project, which involves a total cost exceeding 200 million euros, faced significant delays and technical errors due to these design flaws.

The Court of Audit identified the incident as a result of poor coordination and a lack of diligence on the part of the national rail operator, Renfe. The findings highlight systemic failures in the planning and oversight of the infrastructure project, leading to substantial financial and operational consequences.
