Making the right diagnosis


An optimally functioning drive system stands or falls with the correct diagnosis. This also applies to all associated components. We offer many options in the field of diagnosis. We do this both at your premises and in our workshop, where we perform general diagnoses, damage diagnoses and functional tests. We use a diagnosis to map out the source of any defects. Because every diagnosis is different, our mechanics always visit you first to assess the situation, after which possible causes are reported. Once we have a clear diagnosis, we immediately offer advice, so your drive system or component can be repaired or overhauled. If it is not possible to make an on-site diagnosis, we can remove your engine or component and subject it to an extensive diagnosis on one of our test benches or high-tech test stand. By using calibrated measuring equipment, we will always arrive at a correct diagnosis.

Extensive data history

We inspect your drive system or component in detail before issuing any advice. If required, we can also provide reports, detailing each diagnosis. We store this valuable information, so your data history is always transparent and shows the maintenance progress. This way, we offer you a full-service solution.

Autonomous test stand

We extensively test powerpacks in our workshop. We test-run powerpacks using our fully autonomous test stand and our own hydraulic test bench.


We are ISO/TS 22163 and ISO 9001-certified: as such, we meet international requirements in the field of quality management, supplemented by specific requirements of the railway industry. This way, we continuously maintain our quality level.
