Engineering and consulting

I’m working with CIM/MASTERIS, as part of the AKIEM BB79000 project, on the development and installation of locomotive safety equipment. The technical and sales teams listen well, are available, are responsive and adapt to the needs of the project. The solutions found are relevant and well-structured and we are guaranteed quality of service for the project’s future activities.
