Level crossings in Spain. Suppression programme, cofinancing and portfolio exposure

Spain is a useful reference case because level crossing policy is organised around a legal trajectory of suppression, a national infrastructure manager, a separate high speed infrastructure manager, a national safety authority, an independent accident investigator and a public cofinancing pattern. The high speed network is designed without level crossings. The remaining exposure sits mainly on conventional and metric gauge lines.

The reader gets:

The ADIF and ADIF Alta Velocidad perimeter.
The legal texts that frame suppression and protection.
The role of AESF and CIAF.
The Plan de Supresión and its cofinancing pattern.
Why access substitution matters once suppression becomes a funded project.
Why programme screening matters before engineering.
Where SAMRoute fits beside the public programme.

For infrastructure managers, reinsurers, investors, public finance readers and territorial authorities, the practical question is sequencing. Which crossings are protected. Which are suppressed. Which projects create access substitution issues. Which decisions deserve field review before engineering money and cofinancing commitments are locked in.

1. Spain's residual level crossing perimeter

The mainline rail perimeter in Spain is the Red Ferroviaria de Interés General. ADIF, the Administrador de Infraestructuras Ferroviarias, is the infrastructure manager on the conventional and the metric gauge network under Ley 38/2015 [1, ↗]. ADIF Alta Velocidad is the dedicated infrastructure manager on the high speed perimeter, where new alignments are built without level crossings as a construction standard [1, ↗]. The residual level crossing exposure is therefore concentrated on conventional and metric gauge lines.

The publicly reported figure on the RFIG in 2019 is 3,148 level crossings [2, ↗] [3, ↗], with about half classified as passive, the rest as active under one of the four protection classes set in Article 51 of Real Decreto 929/2020. The total declines each year as the Plan de Supresión and the modernisation programme advance, and the AESF Informe Anual de Seguridad 2025 records a further reduction of level crossing accidents and a continued fall in pasos a nivel pasivos [4, ↗].

For external readers, the distinction matters because the relevant exposure base is not the whole Spanish rail system. It is the remaining conventional and metric gauge portfolio where protection, suppression and access substitution still have to be sequenced. Heritage railways, metropolitan rail systems and other rail operators outside the RFIG carry their own inventories and sit outside the perimeter discussed here.

2. A legal trajectory toward suppression

Spain progressively narrows the conditions under which a level crossing remains acceptable, classifies the crossings that remain, and makes grade separation the structural direction for new or modified infrastructure. The chain of texts reads as a direction of travel rather than a static framework.

The Ley 16/1987 de Ordenación de los Transportes Terrestres [5, ↗] is the founding statute for Spanish land transport regulation.
Real Decreto 1211/1990, which approves the Reglamento of the LOTT, develops the statute and addresses level crossings in Article 235 [6, ↗].
The Orden de 2 de agosto de 2001 develops Article 235 in matters of suppression and protection of level crossings on the network [7, ↗]. The Orden sets the classification by protection class as a function of road and rail traffic, visibility, geometry and accident history.
Real Decreto 1072/2014 [8, ↗] created the Agencia Estatal de Seguridad Ferroviaria as the national rail safety authority.
Ley 38/2015, del sector ferroviario [1, ↗] replaced the prior rail sector law and confirmed the institutional frame for ADIF, AESF and the railway undertakings, with grade separation as the rule for new infrastructure.
Real Decreto 929/2020 [9, ↗] transposed EU Directive 2016/798 on railway safety [10, ↗] and set the operational safety and interoperability framework that applies to ADIF and the AESF.

For programme owners and funders, level crossings are therefore treated as a managed reduction programme, not only as individual assets to inspect. Each text shifts the system one step further toward suppression, grade separation and harmonised protection.

The Santiago de Compostela derailment of 24 July 2013 [11, ↗] sits outside the level crossing perimeter as a high speed event, and reads here as institutional context that accelerated the rewrite producing Ley 38/2015. The Castelldefels collision of 23 June 2010 [12, ↗], in which pedestrians were struck at a station-side crossing on the Barcelona corridor, fed into the CIAF investigation pathway and into the debate on pedestrian exposure at urban and station-side crossings.

3. ADIF, AESF and CIAF

ADIF executes the programme on the conventional and metric gauge networks. That covers the level crossing inventory and the suppression and protection works, with the protection classification framed by Article 235 of Real Decreto 1211/1990 [6, ↗], the Orden de 2 de agosto de 2001 that develops it [7, ↗] and the operational technical specification ETC-PN approved by AESF Resolución 12/2020 [13, ↗].

ADIF Alta Velocidad carries the high speed perimeter where level crossings are designed out by construction standard. The carve out of ADIF Alta Velocidad in 2013 made the institutional split explicit between the conventional residual exposure and the grade separated high speed network [1, ↗].

AESF, the Agencia Estatal de Seguridad Ferroviaria, is the national safety authority. It certifies safety management systems, audits ADIF and the railway undertakings, and publishes the Informe Anual de Seguridad submitted to the European Union Agency for Railways [3, ↗] [14, ↗].

CIAF, the Comisión de Investigación de Accidentes Ferroviarios, investigates rail accidents independently and feeds learning back into the system. It reports to the Ministerio de Transportes y Movilidad Sostenible and publishes its findings on the ministry portal [15, ↗].

The Ministerio de Transportes y Movilidad Sostenible frames national policy and coordinates cofinancing with the Comunidades Autónomas and the ayuntamientos. ADIF's transparency channel and annual reports are the main public reporting on the network, published mostly as institutional documents alongside the less granular open data [16, ↗].

For external readers, this actor map clarifies where infrastructure delivery, safety oversight, accident learning and funding responsibility sit before any independent portfolio reading is added.

4. The suppression programme and the funding chain

ADIF's Plan de Supresión targets 299 crossings with a planned investment of 300 million euros [17, ↗] [2, ↗]. About 200 crossings were suppressed and several hundred more modernised on the existing network over the 2018 to 2021 period.

Suppression is both a safety decision and an access project. The rail-road interface is removed, but a bridge, underpass, road realignment, footpath change or local access solution often has to take its place.

Funding is shared across actors. ADIF carries the rail side investment, the Comunidades Autónomas contribute on the road side and on alternative route works, the ayuntamientos cover local access changes, and the Ministerio de Transportes y Movilidad Sostenible coordinates the national envelope. Specific project envelopes are published in ADIF press releases [18, ↗] and in the corresponding regional and municipal budgets.

In 2022, ADIF, ADIF Alta Velocidad and the Ayuntamiento de Valga in Galicia signed a convenio for the suppression of two level crossings on the Redondela-Santiago line, with the operation valued at around 3 million euros and 2.7 million euros carried by ADIF Alta Velocidad [19, ↗], illustrating the three-tier rail, national and municipal funding pattern.
In 2025, ADIF awarded 3.75 million euros for the renovation and improved protection of eleven level crossings on the Cercedilla-Cotos line in the Madrid region [20, ↗], illustrating the modernisation track that runs alongside outright suppression.
In 2025, ADIF awarded 7.4 million euros for the suppression of two level crossings between Caudete in Albacete and Villena in Alicante [21, ↗], a project that crosses the Castilla-La Mancha and Comunidad Valenciana regional boundaries.

Cofinancing is not an accounting detail. It is delivery risk, timetable risk and prioritisation risk. A technically justified suppression still has to align rail-side works, road-side works, regional budgets and municipal access decisions before the at-grade interface can actually be removed.

5. What the suppression programme has to arbitrate

A crossing can be legally undesirable and still difficult to remove in practice. Suppression closes the at-grade interface and opens the question of how movement is replaced on both sides of the line. For infrastructure managers, the variables grouped around the project read as:

Local road continuity once the at-grade interface is closed.
Alternative route feasibility for the replaced movements.
Works sequencing across the rail-side and the road-side packages.
Corridor operations during construction and after commissioning.
Field review before design freezes the engineering choices.

For reinsurers, the same project reads through a different lens:

Nearby population exposure around the crossing and along the replacement routes.
Emergency response geography and time-to-incident on the new road layout [22, ↗].
Passive versus active protection on the residual crossings that remain.
Road diversion dependency in the period before the suppression is delivered.
Climate and flood exposure on the proposed alternative routes.

For investors and public finance readers, the same project reads through capital-allocation lenses:

Municipal road budgets and the ayuntamiento's capacity to deliver the road side works.
Regional cofinancing under the Comunidad Autónoma's transport budget.
Multi-year programme sequencing across budget cycles.
Projects that cross regional or municipal boundaries.
Exposure to delay before capital is committed to a specific corridor.

These variables enter alongside the safety classification, and they become the substance of a programme decision once the legal direction is set.

6. Why sequencing matters before engineering

Each suppression or protection project involves several million euros, several public funders, road side works and local access substitution [19, ↗] [20, ↗] [21, ↗]. The practical question becomes which sites deserve earlier attention before detailed engineering starts.

The Plan de Supresión runs as a multi-year national envelope. Individual projects extend across several budget cycles. Cofinancing adds regional and municipal calendars on top of the national one. Some projects cross regional boundaries. Commuter corridors around Madrid, Barcelona, Valencia and Sevilla add cadence and access pressure. The screening question therefore appears before works are designed, not after.

The Spanish programme creates this sequencing question structurally. The legal direction is settled. The execution capacity sits with ADIF. The safety oversight runs through AESF and the accident learning through CIAF. What is left is the ordering, and the ordering carries most of the public value at the portfolio level.

7. Where SAMRoute fits

The public programme remains the base. The legal texts define the suppression and protection logic. ADIF executes on the conventional and metric gauge network. ADIF Alta Velocidad keeps the high speed perimeter grade separated by design. AESF and CIAF cover safety oversight and accident investigation. Engineering studies remain project specific. Cofinancing remains political and territorial.

SAMRoute sits before project commitment. It gives programme teams and external readers a repeatable territorial reading of the crossings under consideration.

It helps compare:

which suppressions face the hardest access reroute problems,
which crossings sit near vulnerable populations,
which crossings affect emergency access the most,
which sites combine passive protection, local road dependency and population exposure,
which projects deserve earlier field review before engineering money is committed,
which exposures matter to insurers, infrastructure investors and public finance readers.

SAMRoute reads each crossing against shared geography, repeatable indicators and traceable sources. Monthly refresh is the primary rhythm, with weekly refresh as a target on faster moving indicators where portfolio priority can change between programme decisions.

The European comparison sits alongside that work. Each infrastructure manager reports in its own institutional format, terminology and rhythm [23, ↗] [24, ↗] [25, ↗] [26, ↗]. A shared territorial reading helps external readers compare exposure across markets while keeping national specifics intact.

SAMRoute serves the programme screening layer. It sits before detailed engineering, beside ADIF's public programme, and across the residual conventional and metric gauge exposure under review.
