Unsaturated Characteristics of Fouled Ballast to Support In Situ Identification of Fouling Using Ground Penetrating Radar – Phase I
This research established a protocol for sample preparation and testing between a large suction water characteristic curve (SWCC) device and a large-scale direct shear (LSDS) device using clean ballast and fouling material collected from mainline track. This allowed for comparisons of strength...
Acoustical Warning Device for Locomotive Horns
This report summarizes the research and development of a variable directivity Acoustic Warning Device (AWD) used as a locomotive horn. A Global Positioning System (GPS) was developed to control an arrangement of directional loudspeakers. Loudspeakers are arranged on the locomotive so...
