TER2NNG rolling stock overhaul bogie
CFL: Review of TER2NNG rolling stock bogies
Background & Challenges
In 2020, CFL (Société Nationale des Chemins de Fer Luxembourgeois), national railway operator in the Grand Duchy of Luxembourg, requested the expertise of MASTERIS to assist it in overhauling its rolling stock bogies for 4 years.
The Project Focused On 132 bogies equipping the CFL TER2NNG fleet, whose length of service required a thorough review to ensure the safety, reliability and availability of the equipment. This operation was carried out in partnership with the Technicentre Industriel de Nevers, a key player in The renovation and maintenance of rolling stock as well as PRM (Repairable Equipment Parts).
Objectives
- Review all the component parts of CFL TER2NNG bogies, in order to secure their operational performance.
- Bringing bogies back to their potential at 1.8 million kilometers, to extend the life of the equipment and optimize the availability of the fleet.
- Ensure complete traceability recounting all maintenance services performed on bogies.
The Challenge
- Maintain compliance with the schedule despite a highly disrupted global context due to the restrictive measures put in place by the French government, impacting the industrial organization and logistics of the project.
The MASTERIS solution — Services provided
MASTERIS coordinated and supervised a set of technical services for the complete overhaul of bogies, carried out at the Industrial Technicenter in Nevers:
Preparation and cleaning:
- High pressure washing of frames and removed parts.
- Shot-blasting operations on frames and deposited parts for optimal surface preparation.
Technical controls and interventions:
- Magnetoscopy to detect possible cracks or material defects.
- Boilermaking work for the rehabilitation of structures.
- Geometric control of the frames guaranteeing dimensional conformity.
Management and traceability:
- Global coordination of the project with the Technicenter in Nevers.
- Implementation of an exhaustive traceability system documenting all maintenance operations.
Results
- Service delivered in a turnkey service: coordination and execution of bogie overhaul operations.
- Responsive after-sales service provided by MASTERIS for post-intervention follow-up and the rapid handling of requests.
- Extensive traceability of maintenance operations available for each bogie, facilitating technical and regulatory monitoring.
- Bringing bogies back to their potential in accordance with the objectives, contributing to the extension of the lifespan and the optimization of the availability of the fleet.

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.
