Mediterranean Corridor ETCS delay widens Spain–France gap

Mediterranean Corridor ETCS delay is opening up a clear divide between Spain and France. Spain expects its section to be complete by 2030 with ETCS in place.

France is not planning ETCS deployment on the connecting stretch until 2042, even though ETCS is part of the Core Network requirements, as reported by RailTech.

Since 2018, the Spanish government has tendered more than €7 billion to move the Mediterranean Corridor forward. ERTMS implementation is already underway between Tarragona and Alicante. Meanwhile, France is delaying the rollout of the digital and interoperable signalling on its part of this Trans-European Transport Network (TEN-T) Corridor, complicating a key cross-border connection.

France ETCS deployment 2042 on Montpellier–Béziers–Perpignan

The postponed timetable applies to the Montpellier–Béziers–Perpignan section, where ETCS deployment is now set for 2042. France confirmed this delay in a 2022 report. It has been highlighted again in the third work plan of the European ERTMS Coordinator Matthias Ruete, as European Commission mobility and transport notes.

Spanish media, including El Diario, has revisited the issue and recalled that the announcement was received in Spain as a ‘bucket of cold water’. Separately, the Commissioner of the Mediterranean Corridor, the Valencian geographer Josep Vicent Boira, has left his post eight years after his appointment.

He told the newspaper that trains can still cross the border, but warned that a lack of capacity could emerge in the medium term. He pointed to the international gauge implementation as it progresses between Tarragona and Castellón first, and from Castellón to Valencia later.

ERTMS implementation and the Mediterranean Corridor ETCS delay gap

The ERTMS deployment map for 2030 shows the gap plainly: Spain’s corridor is shown as fully operational with ETCS by 2030, while the French section will not be. Ruete’s work plan cautions that “close coordination between the deployment of ERTMS and the implementation plans of the nine European Transport Corridors is essential to ensure a smooth cross-border rollout”, but it also signals that this alignment does not always happen.

At the same time, Ruete called for stronger governance and coordination, particularly on cross-border sections where misalignment can create bottlenecks and inefficiencies. Also, the work plan urges EU member states to comply with legal obligations and to enter bilateral agreements to help facilitate ERTMS deployment on cross-border routes.

TEN-T Core Network requirements and the 2030 deadline

Under the TEN-T regulation, the core network—covering the most important connections between major cities and nodes—must be completed by 2030, and this includes the implementation of ERTMS. Still, the European Court of Auditors has recently concluded that the 2030 deadline will undoubtedly be missed for completing the Core Network, according to its Special report 02/2026.

The auditors also noted that the European Commission has only once employed its main legal tool to obtain explanations for delays. While new legal tools now exist through the TEN-T revision, the European Court of Auditors stressed that their effectiveness depends on active enforcement.
