Rail System Testing

What Rail System Testing does

RST Rail System Testing GmbH (RST LABS) is a privately held, DAkkS-accredited testing laboratory headquartered in Hennigsdorf, Germany, operating since 2003 with 11-50 employees. The company runs three integrated laboratory divisions: an Environmental Laboratory (climate, corrosion, salt mist, harmful gas, vibration, shock, IP protection, solar simulation), a Fire Laboratory (flammability, flame spread, smoke development, toxicity, heat release rate per EN 45545, NFPA 130, IMO FTP Code 2010, ASTM, and UL 94), and a Materials Laboratory (mechanical-technological testing, chemical analysis, NDT, damage analysis per VDI 3822, SEM, metallography, fastener testing). Its primary vertical is rail vehicles, with secondary service to automotive, maritime, construction, aviation, energy, and emerging robotics customers; it holds DIBt designation for construction products and IMO recognition for maritime fire testing.

The company's revenue model is project-based professional services: customers commission accredited test programs on a quote-driven basis, with no public pricing. GTM relies on a dedicated Head of Sales (Christoph B\u00fccken), direct enterprise engagement, and trade fair presence at InnoTrans in Berlin. Recent strategic emphasis has been on capacity expansion (new IMV 74 kN shaker, quadrupled reverse osmosis water capacity, large salt mist chamber), accreditation scope growth (12 ASTM methods, automotive fire standards, condensation testing per VW/BMW/Daimler K15), and standards leadership via the first gas-corrosion interlaboratory comparison (Ringversuch) with 12 participating labs. The company is led by Managing Directors Dr. Andreas Wende (since July 2022) and Thomas Reppe, with no disclosed external funding or M&A activity.
