Control the lifespan of your rolling stock
A real strategy to put in place to guarantee the control of maintenance costs.
Obsolescence management
Faced with the acceleration of obsolescence on rolling stock or components, the pressure on operating costs, the need to ensure the availability of fleets and ever greater sustainability challenges, operators and owners of rolling stock must rethink the management of their assets.
MASTERIS offers various methods of managing obsolescence, from the storage of electronic components to the reverse engineering of electronic cards or a complete subsystem.
Extending the life of rolling stock
Extending the life of rolling stock is more than just keeping it running. The aim is to guarantee its security, performance and compliance throughout its life cycle, while optimizing investments. This means anticipating supply disruptions, dealing with technological obsolescence, responding to normative changes (especially in terms of EQS), and controlling the industrial impact of the work to be carried out.
Railway operators, mobility authorities, public or private transport companies often face the same challenges:
- Arbitrating between renovation, modernization and replacement
- Ensuring safety and regulatory compliance on old hardware
- Extend the use of a fleet while controlling costs and industrial deadlines
- Capitalize on what already exists while integrating innovations and new market requirements
In this context, MASTERIS is positioned as an expert partner capable of supporting a long-term wealth strategy.
Managing lifespan, a matter of strategy and foresight
01. Diagnosis
We carry out a complete inventory of your equipment:
- Analysis of maintenance history and performance
- Obsolescence mapping (parts, equipment, technologies)
- Identification of regulatory deviations (e.g. safety equipment — EQS)
- This diagnosis provides a factual basis for building an appropriate extension strategy.
02. Lifespan extension studies
Based on the diagnosis, we carry out detailed studies:
- Engineering study for the extension of life of all types of rolling stock or potential organs
- Industrial studies for life extension operations for all types of railway and urban equipment
- Identifying the actions to be carried out to ensure security, reliability and compliance
- Expertise on organs or parts
- Technical feasibility studies
- Estimation of residual life
- Decision support on whether to extend, modernize or replace equipment
03. Obsolescence management
We manage the search for solutions in the face of unavailable equipment, components or parts:
- Identical replacement, adaptation or requalification of the part or component
- Development of alternative solutions (refabrication, reverse engineering, re-design)
- Conducting obsolescence impact studies
- Integration of more modern compatible components
- Establishment of strategic storage or alternative sourcing
04. EQS expertise
We ensure that your machines comply with the latest regulatory requirements:
- Verification of the presence, performance and traceability of EQS
- Regulatory gap analysis (EQS to be replaced, modernized or integrated)
- Migration of rolling stock to ERTMS systems
- Support in the implementation of changes (studies, admission, technical files, implementation)
- Assistance in carrying out maintenance operations on a train or on equipment
- Regulatory watch
05. Design and implementation of industrial operations
In collaboration with our industrial partners, we manage the implementation of decided actions:
- Coordination of operations (renovation, modernization, remotorization, retrofit, etc.)
- Control of schedules, costs and technical interfaces
- Realization in SNCF workshops or with certified partners
- Quality control, testing and validation at the end of operation
06. Strategic support and long-term follow-up
We act as a trusted partner over the long term:
- Wealth strategy advice
- Investment planning
- Post-intervention performance monitoring
- Capitalization of data to feed future technical trade-offs
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.
