Special Bibliography Railroad Safety Reserach

This Special Bibliography prepared from the magnetic-tape files of the Railroad Research Information Service, contains selections which were accessioned between 1973 and 1976. Although the literature which is referenced does in a few cases date back three decades, all listings are considered...

Ballast Fouling Measurement Tool: Phase 1

A prototype man-portable ballast inspection instrument was developed by Earth Science Systems, LLC (ESS) at their facility for use by track inspectors based on ground penetrating radar (GPR) called the RAdar Ballast Inspection Tool (RABIT). During this study, it was determined that the RABIT...

Inspection of Concrete Ties Using Sonic/Ultrasonic Impact Velocity and Impact Echo Measurements

This report documents NDT Corporation’s development of a non-destructive system for inspecting the internal condition of concrete crossties using sonic/ultrasonic impact velocity (IV) and impact echo (IE) measurements. The system, developed at NDT’s facility and tested on numerous railroads in the...

Seismic Testing for Track Substructure Assessment

The University of Illinois at Urbana-Champaign (UIUC) presented equipment, test procedure, and interpretation techniques to rapidly, non-invasively, and quantitatively measure the engineering properties of track substructure (ballast and subgrade). In particular, seismic surface wave testing with...

Low Solar Absorption Coating for Reducing Rail Temperature and Preventing Buckling

This report documents Rutgers University’s research in the development and demonstration of an inorganic coating for reducing peak rail temperature to inhibit rail buckling. The zero-volatile organic content (VOC) and 100 percent inorganic coating system is based on an alkali-aluminosilicate...

Field Demonstration of Geocell Track Substructure Support System Under High-Speed Passenger Railroad Operations

Regions of track, which experience high rates of track geometry degradation, tend to require frequent maintenance interventions that are typically surfacing or tamping. Harsco Rail and the University of Delaware conducted a survey regarding this costly process that involved both machine time and...
