Given the constant demand for heavier, longer, faster, and more efficient rail freight vehicles,
onboard fault detection systems appear as a good approach for enhanced railway asset …

Abstract Machine condition monitoring (MCM) plays an important role in reducing failure
losses in the industry. Appropriate wireless sensor nodes (WSNs) used in MCM will allow …

Axle-box bearing condition monitoring is important for the prognostics and health
management (PHM) of high-speed trains. Temperature is an important indicator of the health …

Distributed acoustic sensing (DAS) using fiber optic cables over an extensive length of
railroads is a well-suited technique for condition monitoring (CM) of railroads. Regardless of …

Abstract Complex Shifted Morlet Wavelets (CSMW) present a number of advantages, since
the concept of shifting the Morlet wavelet in the frequency domain allow the simultaneous …

Die Überwachung von Maschinen und Anlagen zur Gewährleistung und Verbesserung der

The Railway Technology Research Centre (CITEF) has developed a new data acquisition
system (DAS) based on Odroid that allows the measurement of voltage signals (±10 V) for …

Of the three main rail accident types in the United States, derailments are the most common.
Studies have shown that derailments occurring above 25 mph are caused by equipment …

Described herein is a load sensor for a railcar that includes one or more strain gauges and
one or more temperature sensors. The load sensor has a size and configuration that allows …

Currently, railroad bearing temperatures are monitored using wayside infrared devices
known as hot-box detectors (HBDs). HBDs take a snapshot of the bearing temperature at …
