In recent years, remote non-contact NDE techniques have been sought in an effort to improve railroad related inspection operations. More specifically, efforts have been aimed at increasing the inspection coverage and performing dynamic inspections for railroad tracks and wheels. Throughout most of the 20th century, dynamic inspections of railroad tracks have been developed and performed, howeve...

Indian railway is one of the largest networks in country. Its motto “the life line country”, and main transport completed by railways Railroad cheapest safest means transport, but there are also certain accidents on railroad. 60% caused road failures or formation cracks road. Today’s rail systems involve manual track inspection, which cumbersome not entirely effective. However, detection correc...

Railroad equipment manufacturers are surveying a railroad clearance and the environment along rail line to ensure that vehicles can travel safely. Currently, there is need for system accurately measure distance from center of track structures within railroad. Therefore, we have developed 2D-LiDAR create 2D drawings geometry in In this study, propose method detect errors data occur during measur...

As a next generation of Global System for Mobile Communications – Railway (GSM-R), 3rd Generation Partnership Program (3GPP) Long Term Evolution (LTE)/ LTE-Advanced (LTE-A) is considered for railroad wireless communication, i.e., LTE-Railway (LTE-R). Railroad wireless communication has its own requirements and functions since railroad wireless communication is very closely related to safety. In...

Safety is a high priority for any rail system, and there are several safety concerns associated with operating passenger and freight trains on shared-use rail corridors. Adjacent track accident (ATA) is one of the most important concerns. ATA refers to train accident scenarios where a derailed equipment intrudes adjacent tracks, causing operation disturbance and potential subsequent train colli...

Ballast degradation can cause poor drainage, settlement and reduced lateral stability, which adversely affect railroad track safety and performance. Two indices are commonly used in the North American railroad industry to quantify the level of ballast degradation. These are (i) Fouling Index (FI) and (ii) Percentage Fouling (PF). Identifying these two traditional indices involve ballast samplin...
