MECHANICAL ENGINEERING & DESIGN SERVICES

FMW SOLUTIONS PROVIDES

Mechanical Engineering for Railroad Equipment, Machinery & Infrastructure

Railroads depend upon machines operating under some of the harshest conditions found in transportation. Locomotives, passenger cars, boilers, machinery, and specialized railroad equipment are subjected to enormous mechanical loads, thermal stresses, vibration, fatigue, and environmental exposure. Designing, repairing, and improving these systems requires engineering solutions that are both technically sound and practical to implement.

FMW Solutions provides mechanical engineering services rooted in real-world railroad experience. Our engineers work closely with shop personnel, operators, fabricators, and management teams to develop solutions that can be built, maintained, and successfully operated in the field. Our designers seek to find an appropriate balance between performance and cost to suit the goals of each client. The resulting solutions may employ fabrication techniques ranging from welding to conventional machining to CNC machining and even 3D metal printing.

Our commitment to safety is reflected in our participation in various standards development committees with organizations such as AAR, ASME, ASTM, CSA, and NBIC. Design efforts also include industry-standard tools like Failure Modes & Effects Analysis (FMEA) as appropriate to minimize safety issues before metal is even cut.

Engineering Services Questions

Answers to common questions about railroad mechanical engineering, CAD design, finite element analysis, boiler engineering, failure analysis, and technical consulting services.


What types of engineering services does FMW Solutions provide?


FMW Solutions provides mechanical engineering, CAD design, finite element analysis (FEA), boiler and pressure vessel engineering, fluid dynamics, failure analysis, reverse engineering, regulatory documentation, and technical consulting services for railroad and industrial clients.

What industries does FMW Solutions serve?


Our engineering services support freight railroads, passenger operators, industrial railroads, museums, tourist railroads, government agencies, contractors, manufacturers, and private owners throughout North America.

Can FMW Solutions help engineer repairs for obsolete or damaged components?


Yes. Many railroad components are no longer manufactured or lack modern engineering documentation. FMW regularly reverse engineers, analyzes, redesigns, and develops repair solutions for obsolete, damaged, or difficult-to-source equipment.

Does FMW Solutions provide 3D CAD modeling and design services?


Yes. FMW utilizes SolidWorks® and other modern engineering tools to develop 3D models, fabrication drawings, assemblies, repair documentation, and manufacturing packages for railroad and industrial applications.

Can FMW Solutions perform finite element analysis (FEA)?


Yes. FMW provides structural and mechanical analysis services to evaluate stresses, loads, fatigue, repair concepts, and design modifications. FEA can help validate designs, improve reliability, and reduce project risk before fabrication begins.

Can FMW Solutions assist with steam locomotive engineering projects?


Yes. FMW is widely recognized for its expertise in steam locomotive engineering, including boiler calculations, FRA Form 4 development, pressure vessel analysis, combustion systems, drafting systems, fuel conversions, and mechanical design.

Can FMW Solutions help determine why a component failed?


Yes. We regularly perform failure investigations and root cause analyses to help clients understand equipment failures, develop corrective actions, and improve long-term reliability and safety.

Does FMW Solutions only work on historic railroad equipment?


No. While FMW is well known for its heritage railroad work, our engineering experience extends to modern freight locomotives, passenger equipment, industrial rail operations, railroad machinery, infrastructure projects, and emerging technologies.

Can FMW Solutions assist with alternative fuel and energy projects?


Yes. Our personnel have experience supporting alternative fuel research, locomotive fuel conversions, combustion analysis, fuel system development, and emerging railroad energy technologies.

When should I involve an engineer in a railroad project?


The earlier, the better. Engineering involvement during project planning can help identify risks, evaluate alternatives, develop accurate budgets, improve constructability, and avoid costly redesigns or unforeseen problems later in the project.

Can FMW Solutions work alongside our existing staff, contractors, or engineering consultants?


Yes. FMW frequently works as part of larger project teams, providing specialized railroad expertise, technical review, independent analysis, and practical engineering support alongside client personnel and outside consultants.

How do I know if a component should be repaired, redesigned, or replaced?


The answer depends on condition, availability, safety considerations, lead times, operating requirements, and cost. FMW can evaluate the options and provide practical recommendations based on engineering analysis and real-world operating experience.
