Who We Are

OUR HISTORY

Leading Innovator in the North American Rail Industry

For over thirty years, IEM has been the clear industry leader in bringing state-of-the-art metrology to the international rail industry. In 1988, IEM introduced a new standard of excellence and accuracy in wheel wear measurement with the introduction of the Electronic Wheel Gauge. To develop this gauge, IEM conducted an in-depth failure analysis of the existing technology (the Steel Wheel Gauge) and developed an array of new sensor technologies that systematically eliminated the sources of error in railroad wheel wear measurement.

The Electronic Wheel Gauge is still the gold standard in handheld railway wheel metrology. The IEM Electronic Wheel Gauge is the only gauge approved by the AAR Wheels, Axles, Bearings, and Lubrication (WABL) Committee as an alternative to the steel wheel gauge. The IEM gauge is a required measurement standard in locomotive shops throughout North America.

In the 1990’s, IEM, working with CSX and Amtrak, introduced a comprehensive portfolio of automated rail-vehicle inspection technologies, including
  • The in-ground, laser-based Wheel Profile Measurement System.
  • The first Acoustic Defect Identification System.
  • Automated Brake Disc and Brake Pad Measurement.
  • The Hot Wheel / Hot Brake / Hot Bearing Detector.

With the advent of the new millennium, IEM continued with the introduction of
  • The Optical Wheel Flaw Detection System.
  • Strain gauge and Accelerometer-based WILD and WIM.
  • The accelerometer-based Flat Spot Detector.
  • The Transportation Autonomous Device (TAD) – a robot that could automatically identify, grab, and release the air brakes for freight cars in humping operations.
  • On-board Wireless Sensors.

For a complex projects, IEM has a unique railroad metrology eco-system consisting of a large, experienced team. This team has been used by IEM to solve some of the most complex measurement and monitoring problems in railway, aviation, defense, marine, and other sectors.

IEM has designed, patented, and installed the most technically advanced automatic wayside rolling stock measurement and inspection systems as part of our WISE suite of inspection systems at many railroad locations nationally and internationally. IEM has over forty (40) machine-vision and related inspection technology wayside equipment installations worldwide.

IEM’s WISE Systems at various locations have been operating 24 hours/day, 7 days/week, 365 days/year for many years (over hundreds of millions of measurements), measuring tens-of- thousands of wheels per day with a performance rate at +95% and an average false-positive (FP) rate below 1%. This is the benchmark of the railway industry.
