Abstract

A system and method for inspecting a railway track using sensors oriented at an oblique angle relative to a rail vehicle on which the system is traveling. The orientation of the sensors allows for different data to be gathered regarding a particular rail including rail design specifications (gathered based on manufacturer markings detected and analyzed by the system), rail seat abrasion values based on direct measurement of rails from the oblique angle, and other analysis of rail features including joint bars, rail welds, bond wires, rail holes, and broken rails. The use of an air blower, ducts, and one or more air distribution lids over the sensors helps remove debris from blocking the sensors and structured light generators.

Abstract

An autonornous system for generating and interpreting point clouds of a rail corridor along a survey path while moving on a railroad corridor assessment platform. The system includes two rear-facing LiDAR sensors configured to scan along scan planes that intersect but not at all points and wherein neither scan plane intersects a main body of any rail car adjoined to a rear end of the railroad corridor assessment platform. The system also includes a plurality of high- resolution cameras for gathering image data from a rail corridor. The LiDAR sensors and the high- resolution cameras are housed in autonomously controlled and temperature controlled protective enclosures.

Abstract

A system and method for inspecting a railway track using sensors oriented at an oblique angle relative to a rail vehicle on which the system is traveling. The orientation of the sensors allows for different data to be gathered regarding a particular rail including rail design specifications (gathered based on manufacturer markings detected and analyzed by the system), rail seat abrasion values based on direct measurement of rails from the oblique angle, and other analysis of rail features including joint bars, rail welds, bond wires, rail holes, and broken rails. The use of an air blower, ducts, and one or more air distribution lids over the sensors helps remove debris from blocking the sensors and structured light generators.

Abstract

A method and a system for inspecting a railway track are provided. The method comprises the determination of an elevation of a surface of a rail head based on a distance to the rail head from the at least one sensor. An elevation of a surface of a crosstie of the railway track is determined based on a distance to a top surface of the crosstie from the at least one sensor. A total rail height of the rail and underlying rail support height of an underlying rail support are estimated. Crosstie wear value is calculated based on the determined rail head surface elevation, crosstie surface elevation, and estimated total rail height and underlying rail support height. Advantageously, the crosstie wear value can be calculated without requiring the sensor(s) to capture data from which a surface elevation of the underlying rail support can be directly measured.

Abstract

A method for remediating hazardous materials susceptible to nucleophillic attack is disclosed wherein sodium hydroxide is applied to a treatment zone in situ for raising the pH of the treatment zone to at least about 12.5 so that alkaline hydrolysis effectively breaks down the hazardous substance by replacing a leaving group with a nucleophile. The method is well suited for in situ use in the vadose zone to treat contaminated soil and groundwater.
