The study provided the Washington Metropolitan Area Transit Authority with recommendations for trackwork design standards and criteria for use as a basis for the final design of trackwork for the entire METRO rail rapid transit system. The recommendations were based on analytical studies and the experiences reported by operating properties. Trackwork components were analyzed considering different combinations of components and varying physical parameters such as size, spacing, and estimated life of elements of the track structure. The report includes recommendations on rail weight, rail type, rail welding, fastener types and spacing, cross tie types and spacing, roadbed and ballast section, special trackwork, track appurtenances, track gauge and in-service test installations.
