Reason for being

MASTERIS is a unique model in the railway world and that is what makes it strong.

A 100% subsidiary of SNCF Voyageurs, MASTERIS was created with a singular mission: to make the historical expertise of the “Material Department” accessible to other railway players, beyond the SNCF Group.

MASTERIS combines the roles of intermediary, technical facilitator and strategic partner.

A well-oiled mechanism... to shine

Behind each train that circulates safely, there are precise gestures, rare know-how.

It is this know-how that MASTERIS values with transport operators, manufacturers or organizing authorities. Translating needs into technical solutions, orchestrating complex services, guaranteeing quality... that is all this, the daily life of MASTERIS.

Progressive integration, strong recognition

Although the model may have surprised at the beginning, MASTERIS was able to convince: by its ability to listen, by the value it creates, by its intimate understanding of the challenges in the field.

More than a service provider, a partner

MASTERIS is above all a committed team, which creates links between worlds.

Between technology and customer needs. Between SNCF Voyageurs and its partners. Between industrial requirements and commercial flexibility.

Unclassifiable? Maybe.

Indispensable? More and more.
