Total responsibility from start to finish
When we carry out project-based maintenance, we assume full project management responsibility. This includes planning and coordination, regular status updates, procurement of parts, management of subcontractors, transport, and logistics. We ensure that all aspects of the project are interconnected and delivered in accordance with the agreed quality, timeline, and cost. Every project has a dedicated project manager.
Project-based maintenance for all of the Nordics
Mantena offers project-based maintenance to railway companies throughout the Nordics. We have carried out both large and small projects for clients in the region and know that we deliver a competitive service. We have extensive experience operating trains across borders.

Why choose Mantena
We share our clients’ ambitions! A well-maintained train requires more than just daily maintenance. Technical systems must be upgraded, damages must be addressed continuously, and both the interior and exterior need regular overhauls. Well-maintained trains ensure that trainsets are in service as much as possible throughout a long lifecycle. Both train operators and vehicle owners want to take the best possible care of their trains. So do we.
We have what it takes
- Professional organisation prioritising safety and quality
- Solid knowledge and extensive experience in project-based maintenance
- Local operational management closely linked to the project department to ensure strong delivery
- Comprehensive planning and coordination of projects

Norske tog
Mantena is flexible and solution-oriented. They have delivered particularly well on everything related to electrical work, as they have experience in these areas and are highly familiar with the existing documentation for the vehicles, says Rune Andreassen, Project Manager, Norske tog.
SJ Norge
Mantena has developed a forward-looking solution that communicates with an older existing system in the train. With this solution implemented on all 93 sets, improvements will be seen in several areas. For passengers, this will mean better accessibility and punctuality, says Erik Suul Comerford, Head of Rolling Stock Follow-up at SJ Norge.
