This digest provides a brief description of the products developed from Transit Cooperative Research Program (TCRP) Project C-3, "Wheel/Rail Noise Mitigation," which was conducted by Wilson, Ihrig & Associates, Inc. The research included a comprehensive literature review of wheel/rail noise control practices; a survey of all North American and selected foreign heavy and light rail transit agencies to ascertain their current wheel/rail noise-mitigation techniques and their related experiences (both good and bad); a compilation of wheel/rail noise-mitigation field test reports from transit agencies and product manufacturers and suppliers; and field tests of several noise-mitigation measures at several transit agencies. From these activities, a "Wheel/Rail Noise Control Manual" and an accompanying software tool were developed. |
