How to obtain SNCF Réseau qualification?

Submit a qualification file specifying the target work families. The file includes human resources, equipment, references and quality certifications. An audit may be conducted. The process takes 3 to 6 months. Qualification is valid for 5 years.

Can an SME bid directly for SNCF Réseau contracts?

Yes, but direct contracts mainly concern small operations or specialised lots. For major projects, subcontracting to large contractors is more realistic initially. SNCF Réseau also has an SME programme with reserved contracts.

What authorisations are mandatory for working on the railway network?

Staff must hold: railway medical and psychological fitness, essential safety task training, electrical authorisation for catenary works, and railway risk training. EPSF monitors compliance.

Railway Technical Proposal: Winning SNCF and RATP Procurement Contracts

The French railway sector represents a massive market: SNCF Réseau invests over €6 billion per year in network modernisation, RATP continues the Grand Paris Express, and regions are massively renewing their TER fleets. For SMEs, these contracts offer considerable opportunities but require in-depth knowledge of specific procedures, required qualifications, and railway safety constraints. This guide details how to structure a convincing technical proposal for this sector.

The market in figures

French public procurement open data, 12 rolling months as of 2026-08-28. Amounts and durations are medians.

53: contracts awarded
42: winning companies
19: active public buyers
100,000 EUR: median amount
12 months: median duration

What these figures tell you

With 42 winning companies for 53 contracts, a company wins on average 1.3 contract(s) per year in this segment.

The median amount of 100,000 EUR indicates the size of consultation to target first.

The median duration of 12 months shows how often these contracts return to tender.

The median is used rather than the average: a handful of very large contracts is enough to distort an average.

Structure of the French Railway Sector

Understanding the sector organisation is essential to target the right contracting authorities and adapt your proposal.

SNCF Réseau, SNCF Voyageurs, RATP: Who Buys What?

SNCF Réseau manages infrastructure: tracks, catenary, signalling, engineering structures. It is the primary buyer for railway works. SNCF Voyageurs purchases rolling stock, maintenance services, station services and liveries. RATP covers metro, RER, tramway and bus in Île-de-France. Regions, as organising authorities, issue tenders for TER services and rolling stock acquisition.

EPICs and Contracting Entities: Specific Rules

SNCF Réseau and RATP are contracting entities subject to Book III of the Public Procurement Code (special sectors). Publication thresholds are higher. Negotiated procedures are more frequent than in standard contracts. The proposal must demonstrate knowledge of these procedural specificities.

Multi-Award Framework Agreements: The Sector Standard

Most railway contracts are awarded as multi-award framework agreements with mini-competitions. The proposal must be designed for both levels: initial framework agreement application (general capabilities, resources, qualifications) and subsequent contract responses (technical and pricing specifics for each operation).

Qualifications and Prerequisites

The railway sector imposes specific qualifications without which bidding is impossible.

SNCF Réseau Qualification System

SNCF Réseau uses a qualification system. Companies must be qualified in specific work families: track (laying, renewal, tamping), catenary, signalling, telecommunications, railway civil engineering. Qualification is obtained after technical file review, possible audit and validation by the qualification committee. The process takes 3 to 6 months.

Safety Authorisations: EPSF, Safety Tasks

The EPSF (Public Railway Safety Authority) issues safety approvals. Personnel working on the national railway network must hold specific authorisations: essential safety tasks (TES), medical and psychological fitness, railway risk training. The proposal must present the number of authorised staff by category.

Quality Certifications: ISO 9001, ISO 45001, IRIS/ISO-TS 22163

ISO 9001 is a minimum. ISO 45001 (occupational safety) is almost systematically required. For rolling stock and components, IRIS (ISO/TS 22163) is the international reference. The proposal must list certifications with their scope, certifying body and renewal date.

Writing the Railway Technical Proposal

The railway technical proposal must demonstrate mastery of specific constraints: traffic safety, work windows, co-activity.

Traffic Safety and Prevention Plan

This is THE discriminating criterion. The proposal must detail: management of work windows, safety procedures (train announcements, safety agents, marking), co-activity with other companies and traffic, the site-specific prevention plan. Quantify: number of safety agents, accident frequency rate, zero-accident policy.

Site Organisation Under Railway Constraints

Railway works are executed within very constrained time slots: nights, weekends, low-traffic periods. The proposal must present a detailed planning integrating: work window requests, supply via work bases, railway logistics (work trains), waste management in railway zones, and track reinstatement within imposed deadlines.

Specific Equipment and Approvals

Work rolling stock (tamping machines, ballast regulators, work trains) must be approved for circulation on the national network. The proposal must list: track machines, approved railway lifting equipment, road-rail vehicles, measuring instruments. For each: type, capacity, approval, availability.
