Acquisition

Acquiring new rolling stock represents a major strategic investment. The equipment must meet operational needs, while complying with technical and budgetary regulations. We support you to secure technical choices, optimize commissioning times and make the overall cost of the project reliable.

Approval

Approval is a key step in ensuring that rolling stock complies with national and European standards. We manage the entire process, from the certification strategy to the constitution of the technical file, in order to limit the risks of delay or non-compliance.

Operation & Maintenance

Operators must guarantee the punctuality and safety of their traffic while controlling operating costs. This involves effective management of preventive and corrective maintenance, rigorous fixed asset planning, and a clear vision of the state of the fleet at all times.

Optimization

Reducing ownership costs, improving operational performance: we offer innovative solutions (predictive maintenance, digitalization, reliability analyses) to better anticipate failures, adapt maintenance strategies and maximize the availability of trains.

Life span management

Controlling the aging of equipment is essential to ensure reliable and profitable operation. MASTERIS has a clear vision of the life curve of assets and offers adapted maintenance strategies, as well as support to balance between heavy maintenance, renewal or transformation.

Spare parts

A reliable and rapid supply of parts is essential to maintain continuity of service. MASTERIS secures the supply chain, anticipates needs and offers alternative solutions to the risks of obsolescence.

Maintain/restore potential

At mid-life, rolling stock requires targeted renovation operations to remain in line with operational requirements. MASTERIS brings its expertise in technical diagnosis, the programming of interventions and the management of complex projects to extend the value of rolling stock.

Transformation/modernization

Faced with regulatory, technological or commercial changes, it is sometimes necessary to change your fleet. Whether it is a question of passenger comfort, accessibility, energy or digital technology, modernization must combine technical ambition, time management and return on investment.

Repair

After an incident, the challenge is to restore operational capacity as quickly as possible, without neglecting safety.

Meet performance, deadline and compliance requirements.

Secure the commissioning or re-commissioning through a rigorous and recognized approach.

Ensure availability, reliability and safety on a daily basis.

Gain in performance thanks to data and maintenance engineering.

Anticipate obsolescence and secure investments over the long term.

Guarantee the availability of parts to avoid prolonged shutdowns.

Extend operational life without compromising performance.

Adapting equipment to new uses and market requirements.

Quickly bring damaged or damaged equipment back into service.

Your single point of contact

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 centers
5 engineering clusters

Let's discuss your rail challenges

A MASTERIS expert answers you quickly to assess your needs — without commitment.

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.
