Abstract:

In this initial phase, conducted from March 2015 through December 2016, Vista Clara and its subcontractor Zetica Rail successfully developed and tested a man-portable, non-invasive spot-check nuclear magnetic resonance (NMR) moisture sensor that directly measured moisture on water content in railway ballast materials. All technical objectives were successfully completed, including a successful April 7, 2016, demonstration of the prototype sensor on an active railway line in Southeastern Virginia.
