Railway service contractors must apply retroactive economic terms from January 2026

The Directorate General of Labor has officially registered and published the Resolution of July 22, 2026, regarding the XXIV Collective Agreement for Railway Contracting (BOE-A-2026-17061). This new legal framework establishes the labor relations for companies providing essential services to the railway sector, including maintenance, cleaning, and logistics operations. While the agreement enters into force the day after its publication, it introduces a significant retroactive economic mandate that requires immediate administrative and financial adjustments by all affected entities.

What changes

The primary shift introduced by this resolution is the retroactive application of economic conditions. According to Article 3 of the agreement, although the legal validity begins upon publication, the economic effects are backdated to January 1, 2026. This means that any salary increases, allowances, or economic benefits stipulated in this Collective Agreement (Convenio Colectivo) in Spain must be calculated and applied as if they had been in effect since the start of the year.

Furthermore, the agreement defines a clear temporal scope. As stated in Article 4, the agreement has a fixed duration of four years, which will conclude on December 31, 2029. This provides long-term legal certainty for both employers and employees regarding the labor conditions that will govern the sector during this period.

The functional scope has also been meticulously detailed to prevent ambiguity. Article 2 expands and clarifies the types of services covered, ensuring that it is not merely about train cleaning, but encompasses a wide array of auxiliary and complementary railway services. This includes disinfection, pest control, cargo loading/unloading, and complex maneuvering tasks such as the use of shunting locomotives, crane gantries, and fuel provisioning for diesel engines. It also explicitly includes personnel involved in high-speed line maintenance, such as gauge changer operators and route accompaniment agents.

Context

The railway sector in Spain has undergone significant structural changes following the implementation of Law 39/2003, which reorganized the industry. The transition from the former RENFE entity to the current structure—comprising Administrador de Infraestructuras Ferroviarias (Adif) and RENFE-Operadora—necessitated a specialized regulatory framework for outsourcing. This agreement serves as the essential legal bridge between these large public entities (the concessionaires) and the private companies (the contractors) that execute specific tasks through firm contracts.

In the broader landscape of Spanish labor law, collective agreements are the primary tool for adapting general statutes to the specific technical and economic realities of a sector. By registering this XXIV agreement, the administration ensures that the specialized needs of railway logistics—such as the high-risk nature of maneuvering or the specific hygiene requirements of train disinfection—are addressed with precision, preventing the legal vacuum that often occurs during the transition between successive agreements.

Who is affected and how

Large Railway Concessionaires and Contractors
Major companies that hold service contracts with Adif or RENFE-Operadora are directly impacted. These entities must immediately audit their current payroll structures to ensure compliance with the retroactive economic terms. Failure to apply the January 1, 2026, backdated increases could lead to significant labor disputes and administrative sanctions. They must also ensure that all service contracts with sub-contractors align with the new functional definitions provided in Article 2.

SMEs (Small and Medium Enterprises) in Railway Logistics
SMEs providing specialized services such as cleaning, maintenance, or cargo handling are heavily affected. For these companies, the retroactive nature of the agreement (Article 3) represents a sudden cash flow requirement, as they must settle the difference between the old rates and the new rates for the months already elapsed in 2026. Accurate bookkeeping and immediate payroll updates are mandatory to avoid legal liability.

Self-employed Professionals (Autónomos)
Individual service providers who fall within the functional scope defined in Article 2—such as specialized technicians in railway maneuvering or maintenance—must ensure their service pricing and labor costs reflect the new standards. While they may operate as independent contractors, the collective agreement sets the benchmark for the labor costs they must account for in their business models.

Railway Workers
Employees working in disinfection, cleaning, loading/unloading, maneuvering, and technical maintenance are the primary beneficiaries. They gain legal certainty regarding their working conditions and are entitled to receive the economic differences owed from January 1, 2026, as per the mandate in Article 3. The agreement also ensures their rights are protected across the entire Spanish territory (Article 1).

What to do and when

To ensure full compliance with BOE-A-2026-17061, affected parties should follow this timeline:

• Immediate Action: Conduct a payroll audit to identify the economic gap between current payments and the new requirements of the XXIV Collective Agreement.
• Immediate Action: Calculate the retroactive amounts owed to employees for the period between January 1, 2026, and the current date, as mandated by Article 3.
• Within the current month: Update all internal labor policies, job descriptions, and salary scales to reflect the functional scope defined in Article 2.
• Ongoing: Monitor the expiration date of December 31, 2029, to begin planning for the next round of negotiations well in advance.

Given the complexity of retroactive calculations and the specific functional definitions of this agreement, we recommend that companies consult with the labor department at BMC to evaluate their specific situation and ensure all adjustments are executed correctly.
