The CNMC has approved a resolution regarding OUIGO's complaint about the delay in responding to their capacity reservation request on certain rail lines. The delay has led to a demand for a response within a month.

Agreements for capacity reservations provide certainty for railway companies to invest in assets like trains with long amortization periods. The European Regulation requires infrastructure administrators to respond promptly to such requests.

ADIF Alta Velocidad is required to establish a procedure for handling capacity reservation requests in the upcoming modification of their network declaration, with a maximum duration of eight and a half months.
