SHARMA & ASSOCIATES INC

Sharma & Associates Inc. specializes in advanced engineering research and development for transportation safety systems, with deep expertise in railcar dynamics, fire testing, and impact simulation. The firm designs and executes physical and computational tests for tank car thermal protection, rollover resilience, and puncture resistance, leveraging proprietary simulation tools like the Train Energy and Dynamics Simulator (TEDS). Their work includes developing repeatable test setups for small-scale railcar components, conducting full-scale fire experiments on DOT-112 tank cars, and performing track/train dynamic simulations to evaluate multi-vehicle consist behavior under extreme conditions. A key differentiator is their ability to bridge empirical testing with high-fidelity modeling, supporting the Federal Railroad Administration’s safety standards through data-driven validation of rail equipment performance under hazardous scenarios. The contractor maintains a strong, consistent relationship with the Department of Transportation, particularly the Federal Railroad Administration, delivering technical services that directly inform regulatory decisions on rail safety. Their portfolio centers on experimental research, test facility development, and performance evaluation of rail infrastructure and rolling stock, with a clear focus on mitigating risks associated with hazardous material transport. While the General Services Administration appears in their history, the overwhelming majority of their work is mission-critical and directly tied to DOT’s safety and innovation priorities. Their primary technical focus lies in NAICS 541330 (Engineering Services) and 541715 (Research and Development in Physical and Engineering Sciences), reflecting a niche positioning at the intersection of applied mechanics, materials testing, and transportation systems engineering. They serve the rail and energy sectors by translating regulatory requirements into actionable engineering solutions, particularly around tank car integrity and operational safety. Sharma & Associates Inc. is a small business structured as a 2L entity based in Hinsdale, Illinois. While they hold no formal government certifications, their sustained engagement with DOT on high-complexity, safety-critical projects establishes them as a trusted technical partner in the federal transportation research ecosystem.
