01Aligning technical and regulatory requirements before manufacturing begins to prevent costly mid-project corrections.
A specialized quality and engineering partner for passenger trains, high-speed rail, metro systems, trams and freight wagons — in steel and lightweight aluminium.
Founded in February 2017 by a team working continuously in the railway business since 1998.
What truly sets us apart is our diverse, international team of experts from different nations, including Slovak, Polish, Serbian, and Croatian professionals. This multicultural background allows us to break language barriers, seamlessly navigate different regional regulations, and provide highly flexible, on-site support directly at manufacturing facilities.
With deep technical expertise in both steel and lightweight aluminium constructions, we help operators mitigate risks, achieve strict compliance, and deliver maximum product reliability.
Aligning technical and regulatory requirements before manufacturing begins to prevent costly mid-project corrections.
Verifying mechanical and structural designs to ensure they meet international rail standards.
Establishing robust quality management workflows that safeguard every phase of the vehicle manufacturing process.
Conducting independent, thorough evaluations of internal factory processes and supply chain compliance.
Specialized oversight and certification compliance, including inspection of critical weld joints on car-bodies, bogies, and complex aluminium structures.
Maintaining a constant on-site technical presence on the factory floor to monitor assembly, material handling, and craftsmanship.
Leading the ultimate witness testing, inspection, and sign-off protocols to secure seamless vehicle handover and commissioning.
We provide independent engineering and quality assurance throughout the entire rolling-stock production lifecycle — from specification and design review to final acceptance.
One partner. One continuous quality perspective.
From early-stage requirements and design verification through manufacturing, testing, and final acceptance.
An objective layer of control that helps identify technical, quality, and compliance risks before they become costly issues.
Specialized knowledge of rolling stock, international railway standards, manufacturing processes, and regulatory requirements.
Our experts work directly on the factory floor, monitoring production, assembly, materials, workmanship, and compliance.
Dedicated expertise in the inspection and compliance of critical welded structures, including car-bodies, bogies, and aluminium structures.
We assess manufacturing processes, quality systems, suppliers, and production controls — not just the finished vehicle.
Identifying potential issues early helps minimize rework, delays, production disruptions, and unexpected costs.
We support witness testing, final inspections, documentation, and sign-off to ensure a controlled and confident vehicle handover.
From the first specification to the final handover, we help ensure every vehicle meets the required standards, quality, and performance expectations.
We have satisfied the needs of well-known European customers, among others: NS (Dutch Railways), DSB (Danish Railways), Deutsche Bahn, Pasažieru vilciens (Latvian Railways), freight wagon operators NACCO, Modalis, GATX, ATIR, Wascosa, tram and metro operators and an electric bus operator.
Our vision is to be the most trusted international partner in rolling stock quality management and engineering excellence.
