CNMC orders Adif to free up goods‑terminal siding capacity within three months
Executive summary: The CNMC issued a resolution requiring Adif to submit, within three months, a report on actions taken or planned to free capacity in the sidings of goods terminals. Freeing siding capacity can relieve congestion, increase rail freight throughput and reduce logistics costs for shippers.
Who is involved: CNMC (regulator), Adif (rail infrastructure manager), freight terminal operators and rail freight companies.
Likely next: Adif must deliver its report by 2026-11-16; the CNMC will then assess the submission and may launch sanctioning proceedings if the measures are deemed insufficient.
Spain's competition authority has given railway infrastructure manager Adif a three-month deadline to detail how it will release siding capacity at freight terminals, marking a targeted intervention in a long-standing logistics bottleneck. The CNMC's order responds to evidence that limited track access at key hubs restricts train paths, inflates dwell times and ultimately raises costs for shippers attempting to shift volume from road to rail. By demanding a concrete remediation plan rather than merely monitoring outcomes, the regulator signals that structural underinvestment in terminal capacity can no longer be treated as an operational externality. The move aligns with broader European objectives to double rail freight's modal share by 2050, a target that remains elusive in Spain where rail carries roughly 4% of surface freight tonne-kilometres. Freeing sidings would allow new entrants and existing operators to schedule more reliable services, improving the economics of intermodal corridors such as the Mediterranean and Atlantic axes. It also complements the CNMC's parallel demand that incumbent Renfe grant competitor Iryo access to maintenance workshops, suggesting a coordinated push to dismantle vertical barriers across the rail value chain. Adif's response will likely combine short-term scheduling reforms with medium-term capital projects — loop extensions, automated yard management and dedicated freight windows — financed partly through EU recovery funds. The three-month reporting window creates immediate pressure for visible progress, while the threat of follow-up sanctions ensures the issue stays on the infrastructure manager's investment agenda through the next regulatory cycle.
Timeline
- — La CNMC da tres meses a Adif para liberar vías en terminales de mercancías (Expansión)
- — La CNMC pide a Renfe que permita el acceso de Iryo a sus talleres (Expansión)
Analysis — what this means
Likely next events
- Adif must submit its capacity‑freeing report to the CNMC by 2026-11-16.
Sectors affected
- Rail freight logistics
- Intermodal terminal operations
Regulatory implications
- CNMC can initiate sanctioning proceedings under Spanish competition law if Adif fails to meet the three‑month deadline.
Historical parallels
- On 2026-08-11 the CNMC requested Renfe to allow Iryo access to its workshops, showing a recent pattern of CNMC issuing specific directives to rail infrastructure managers.
