Clark Testing has a long history of mechanical testing, equipment qualification and product validation for the heavy and light rail industry. We have provided testing services for locomotive and freight car equipment manufacturers along with component testing services for passenger rail cars and people movers.
Our fully accredited ISO 17025-2017 labs have provided comprehensive testing services for the rail industry such as structural, vibration, thermal, load & fatigue, life cycle aging and EMC/EMI testing. Clark’s testing and validations services to railcar manufacturers are in accordance with AAR, APTA, EN, MIL-STD, ISO and IEC Standards.
Clark’s engineers collaborate with our customers to develop test programs to simulate the operating environment and functional operation of their specific components. These programs are designed to meet the industry testing standards and customer specifications.
Typical test objectives include:
Design verification and certification according to a specific standards or client specifications.
Component performance characterization and validation to comply with contract requirements.
Finite element analysis and root cause analysis

Clark Testing has the infrastructure and engineering experience to meet the mechanical testing requirements of the rail industry. In addition to our structural & fatigue testing capabilities, we also provide vibration, shock EMC/EMI and thermal testing services. Having quality data from actual field conditions that components and equipment are subjected to in the field is critical in solving reliability issues.
Clark Dynamics has the environmental chambers to accelerate aging and validate functional performance for longer product life expectancy. Clark can accommodate large component aging for extended periods simulating containment internal conditions as high as 170C.
Common to automated systems and electronics in the industry is the requirement to ensure electromagnetic compatibility of components and mitigate vulnerability to outside sources. Emissions and Immunity analysis provides insight as to the potentially undesirable propagation and reception of electromagnetic energy and radiofrequency interference.
Unique to each test specimen are its functional and design-basis lifetime requirements. Clark’s facilities have the equipment and technical expertise to test a variety of components for mechanical fatigue and failure, life cycle, aging, accelerated aging, and simulation.
Clark Testing’s Vibration laboratory has multiple hydraulic and electrodynamic shakers making Clark Testing the ideal fit for all your testing needs. Our Vibration laboratorys' investment in new equipment has led to Clark Testing being an industry leader in Vibration Testing.
Clark Testing has been in the powertrain & gearbox testing business for over 20 years. Over that time we have tested products ranging from small components such as starters and air motors to transmissions and axles in excess of 2000 horsepower. ciency for anything from heavy off-road industrial equipment to high performance motorized competition vehicles.
The Fuels and Lubricants lab specializes in wear testing of products based on test rigs such as Four-Ball wear, Hydraulic Pump Wear, and FZG Gear. Clark Testing Fuels & Lubricants Laboratory is fully equipped to perform tests ranging from routine analyses to quality control.
Clark Testing continuously operates under stringent quality assurance guidelines ensure all policies, practices and procedures meet or exceed industry standards. Clark’s QA/QC programs follow the accreditation guidelines of ISO 17025-2017, 10CFR50 Appendix B, NQA-1 and AIHA.
