For over 80 years, Sperry has been an innovative force in rail flaw detection. For us, serving our customer embodies more than supplying the most advanced technology in the industry: it is about providing a total solution that offers our customers a more cost-effective, time-efficient way to operate.

Through continuous development and the expertise of the highest trained workforce in the industry, we help railroads around the world maximize productivity and safety. From heavy haul networks to metropolitan systems, Sperry sets the standard for industry inspection techniques.



The latest innovation from Sperry, our exclusive X-Fire technology uncovers difficult to fund defects before they become a liability. The obliquely angled probes call out flaws that are difficult to find with standard ultrasonics alone, such as reverse detail fractures and transverse defects in spite of certain surface conditions such as head checking, shells, and worn rail profile is the most advanced available today.


Sperry’s induction technology accurately uncovers potentially catastrophic defects in the head of the rail such as transverse defects and vertical split heads. Our induction technology is more tolerant of lateral position and surface anomalies such as grease than any other testing method.

Standard Ultrasonics

For full head to base coverage, we apply ultrasonics via our Roller Search Units (RSUs). Sperry RSUs ensure uniform and constant contact with the rail, even when applied to less than perfect rail conditions, ensuring higher defect-detection ratios.


Developed and lead by a Level III certified instructor with over 40 years experience.

Over 90% of our graduates earn Level II certification.

Class sizes limited to 6-8 students to ensure individual attention.

Hands-on training using hand units and other inspection tools.

State-of-the-art facility includes a rail sample library, simulation room, complete inspection vehicle, and test track.

Courses offered include:

Level I Rail Testing, Level II Rail Testing, Hand Testing, Portable Rail Flaw Detectors, Gates & Gains, B-Scan Interpretation, Test System Familiarization, Roller Search Unit (RSU) Maintenance, Induction Testing, Personnel Qualification & Certification, 10-week Chief Operator Class. Customized programs also available.


“The Sperry School did a terrific job education our employees on all facets of rail flaw detection. The hands-on training in the lab and on the test track helped us make better decisions in real lift situations, ultimately reducing inspection time and saving money for our organization.”

Al Mauldin, Engineer – Rail Testing, Norfolk Southern
