• Abstract:
  In support of the Office of Rail and Construction Technology of the Urban Mass Transportation Administration, the Transportation Systems Center (TSC) is conducting analytical and experimental studies to relate transit truck design characteristics, wheel/rail forces, and wheel/rail wear rates, in order to provide options for reducing the wear rates of wheels and rails experienced by transit properties and minimizing system life cycle costs of vehicle and track components, while maintaining or improving equipment performance. As part of this work, TSC planned and implemented an expanded Phase II measurements program in order to obtain onboard wheel/rail force measurements over a representative range of the Washington Metropolitan Area Transit Authority's (WMATA's) operation conditions; obtain data to quantify the load environment of direct fixation fasteners and evaluate the influence of changes in fastener characteristics on performance; evaluate the influence of taper and suspension modification on high speed stability; and assess the feasibility of a retrofit to the WMATA truck to improve curving performance. These tests were conducted in the Fall of 1981.
