For future "Smart Car" capabilities and many of the monitoring capabilities desired for condition-based maintenance, it is important to be able to incorporate wireless technologies across the entirety of the railway infrastructure. Such a design would allow monitoring of car and locomotive...

The key to wireless sensor systems in practical applications is power supply. By its very name, "wireless" implies that even the power for the system must be self-contained within the monitoring sensor nodes. Even if, with low power usage and proper design, small enough batteries could run the...

Security monitoring is one of the major issues facing the nation today. While human observers theoretically offer the greatest security, manpower demands are prohibitively expensive and come with the drawbacks of human inattention and limited senses. Current automated systems offer some relief, but...

For transit or for freight, the railcars are the workhorses of the industry. Whether it's people, raw ore, liquid gases, or finished products, the cars must safely and reliably carry their cargo from point to point. Deceptively simple in appearance, railcars are still often complex interrelated...

The IEM Wheel Diameter Gauge enables operators to generate accurate wheel circumference or diameter readings without the use of a wheel tape. It is now practical to monitor wheel diameter variations during routine scheduled maintenance inspections while the wheel is still mounted on the car or...

IEM's railroad Laser Wheel Profilometer, laser scanning with wireless PDA, can assist you with maintaining overall quality control for wheel profiling and conformance with wheel specifications, or provide "hard" data for evaluation of railroad wheel maintenance strategies. Key Features and...

No moving components to wear and break - only a light contact plate to assure alignmentHigh-speed laser scan continuously profiles rail in motionDetect and classify wear and significant flaws/damageAutomatic logging and data recovery The Laser Rail Profilometer eliminates moving gauge components...

In 1987, IEM changed the way railroads measured wheels with its Electronic Wheel Gauge, the only electronic gauge approved for use by the American Association of Railroads. The Mini-EWG does away with the separate controller and attached cable and now incorporates electronic controls, keypad, and...
