Restoring the Potential of Your Rolling Stock
MASTERIS has specific expertise in the mid-life maintenance of rolling stock, carried out mainly in the industrial technicians of the SNCF group.
From preparing the program to taking charge of carrying out maintenance work, MASTERIS is committed to you at all stages to restore the potential of your rolling stock.

Mid-life Maintenance of Rolling Stock
Faced with the aging of fleets, the obsolescence of components, new regulatory requirements (accessibility, safety, EQS...), and increasing pressure on investment costs, rail operators must rethink the management of the life cycle of their rolling stock.
Mid-life, a strategic question arises: should we replace, modernize or extend the use of the existing park? Restoring the potential of equipment halfway through its life cycle makes it possible to optimize its use value, to postpone major investments, and to maintain a high level of operational performance.
A global vision of the asset
This approach involves a global vision of the asset, integrating security, compliance, compliance, energy efficiency, passenger comfort, but also adaptation to current uses.
The challenges for operators and organizing authorities are multiple:
- Extend the life of equipment by complying with current standards
- The Trade-Offs Between Partial Renovation, Targeted Modernization or Major Transformation
- Making components reliable, optimizing maintenance costs and securing supplies
- Integrate Technological Improvements Without Calling Into Question the Original Certification
In this context, MASTERIS offers a tailor-made approach to restore the potential of your rolling stock in mid-life, while guaranteeing safety, compliance and industrial control.
A multidisciplinary team
MASTERIS brings together a multitude of skills to prepare and execute the mid-life revision project: rolling stock subsystem experts, maintenance engineers, method engineers, project managers, project managers, purchasers, etc.

To effectively support the mid-life upgrade of your rolling stock, MASTERIS offers an approach in two complementary phases, combining strategic expertise and operational control.
01. Framing and defining your project — Project Management Assistance for the asset maintenance program
- Analysis of the state of the park and identification of priority needs for heritage maintenance
- Assistance in defining the need: development of a global program aligned with the objectives of security, compliance, performance and cost control
- Anticipation of risks related to obsolescence, regulatory changes and industrial constraints
- Strategic Advice on Retrofit or Life Extension Options
- Expertise on all subsystems and organs
- Formalization of specifications and preparation of technical files
- Coordination of stakeholders: operators, organizing authorities, suppliers
- Monitoring of global planning and structuring of decision-making processes
- Consideration of certification issues, operating authorizations or regulatory changes
02. Design, industrialize and manage the execution (MOE)
Engineering studies: design, integration of new components, electrical or mechanical adaptation
Heritage and industrial maintenance:
- Complete overhaul of the machines (body, bogies, chassis...)
- Revision or Replacement of Critical Organs
- Level 4 or 5 maintenance operations
- Modernization projects: comfort, cabin ergonomics, instrumentation, connectivity, performance
- Obsolescence management, integration of alternative solutions or redesign
- Procurement and reconditioning of parts with Supply Chain Support
03. Restarting and Securing the Life Cycle
- Test campaigns, commissioning, securing the return to circulation
- Quality monitoring, regulatory compliance, admission support if necessary
- Updating technical documentation
- Skills transfer: training, tools, specific tools
- Post-operation follow-up to ensure sustainable performance
MASTERIS relies on the resources of SNCF Voyageurs and its network of partners
With MASTERIS, you benefit from a single interlocutor capable of mobilizing all the expertise, services and resources of the SNCF group as well as a national and international network of other partners, to offer complete, efficient solutions adapted to your needs.
Hardware engineering at SNCF is
- 2,200 experts spread over 17 centers across France
- 182 experts from the Synapse network (network of SNCF scientific and technical experts)
- 15 patents filed on average per year
In France, the SNCF group counts on:
- 10 technical center
- 5 engineering clusters
A clear vision of the key stages of your project
In Dakar, we are far from major European rail networks, so in the event of incidents it is important to be able to react quickly and independently. This is why it was important to improve the skills of the teams in lifting our Coradia machines and our work trains. MASTERIS was able to respond quickly and effectively to our expectations.
Within Hexafret, regulatory monitoring already exists on which ECE relies. However, it proved necessary to complete this monitoring in order to cover all the countries in which Hexafret operates, in particular Germany, Spain and Italy. Hexafret therefore turned to MASTERIS in 2024 to provide this service.
After a first year of collaboration, Hexafret satisfied with both the content and the contractual relationship, extended the regulatory monitoring contract in 2025. We appreciate its synthetic side.
