The Comisión Nacional de los Mercados y la Competencia (CNMC), Spain's competition authority, is currently investigating Renfe-Operadora, Renfe Mercancías, and Pecovasa. This investigation has now expanded to include two executives from these companies, indicating a serious inquiry into their business practices.

The CNMC's role is to promote and defend the proper functioning of markets in the interest of consumers and businesses. The authority is focused on detecting and preventing anticompetitive practices that could harm competition and affect consumers negatively.

This investigation highlights the CNMC's commitment to ensuring fair competition within the railway sector, which is crucial for maintaining a balanced market environment. The inclusion of high-level executives suggests that the authority is taking a thorough approach to uncover any potential wrongdoing.
