TechniNat, which is part of the Rolling Stock Division, brings together all the railcar and locomotive maintenance facilities in France to create a single entity with a resolutely innovative approach.

Its vocation is to offer wagon maintenance (initially) and then locomotive maintenance (from 2020) to customers both inside and outside the SNCF group.

Three key components structure TechniNat's DNA

Agility

TechniNat centralizes and manages 10 workshops as close as possible to its customers' operating sites, to be responsive and competitive.

Mobility and proximity

This involves the implementation of new mobile maintenance solutions, offering efficient regional coverage and enabling teams to be at most two hours (or 200 km) from the site of intervention.

Excellence

High-level maintenance services, in line with customer expectations, integrating the technical, industrial and human resources that are the pride of Matériel.

A wide variety of tasks: replacement of torn-off components, troubleshooting, brake testing, repairs following a collision, major general inspection of rolling stock... assignments can range from one hour to fifteen working days.

"TechniNat is a real asset within the SNCF Voyageurs Matériel ecosystem.
Our credo is mobility, responsiveness and 'no limits': just because we don't know how to do something today doesn't mean we won't respond. ETCS, mid-life operations, we're ready to take on many challenges!
