• Abstract:
  The Federal Railroad Administration (FRA) sponsored an all-inclusive parametric study using NUCARS® to assess vehicle performance of five vehicle types over analytically-defined track perturbations. The research team performed the vehicle performance assessment using criteria from both the Association of American Railroads' Chapter 11 and FRA Title 49 Transportation Code of Federal Regulations Part 213 Track Safety Standards. In the simulation work, a matrix of the maximum allowable limits for track alignment, surface and cross-level deviations over Track Classes 1 through 5 was used. The simulation matrix included single track deviations as well as synchronized combined track deviations.
