Failure Analysis & Diagnostics

Rail Surface Imaging System (RSIS)

Rail surface condition assessment is fundamental to assuring optimum rail safety. Rolling Contact Fatigue (RCF), also known as head checking, can cause broken rails that can potentially cause a derailment. Additionally, RCF and other types of surface damage can interfere with ultrasonic rail flaw testing, leaving the rail at risk of having unknown internal rail flaws. ENSCO’s innovative Rail Surface Imaging System (RSIS) uses high-speed cameras to capture detailed images of the rail surface without contacting the rail surface. At the same time, ENSCO’s patented algorithms assess the rail surface to determine the level of severity of RCF and surface damage which can be seen in strip charts synchronized with the images and other inspection data. Rail Surface Imaging Advantages: * Non-contact * High vehicle speed * Images processed to strip chart measurements * Synchronized with other inspection system data * Used to prioritize rail grinding/rail milling * Used to proactively identify surface condition locations that interfere with ultrasonic rail flaw testing The RSIS can be an add-on to the Joint Bar Imaging System (JBIS) or Track Component Imaging System (TCIS). Or alternatively it can operate stand-alone.

Track View Imaging System (TVIS)

ENSCO’s Track View Imaging System (TVIS) operates similarly to the Track Component Imaging System (TCIS), but it utilizes an area scan camera. This allows it to provide overview imagery of the ties and fasteners in a cost effectively manner. The TVIS is synchronized with all other systems, and it is very useful to provide context to defective conditions detected by other systems.

Track Component Imaging System (TCIS)

The machine vision capability of the Track Component Imaging System (TCIS) allows for a visual inspection of train control components installed on the track such as balises and transponders. This allows railways to identify problems of broken, missing, or incorrectly located wayside transponders which can result in incorrect train control operations.
