The purpose of the Type II Truck Test Program was to obtain performance data on several Type II (or premium) freight car trucks in order to characterize their operational behavior. Data were acquired in the performance regimes of curve negotiation, lateral stability, trackability, and ride quality. Tests were also conducted to obtain rolling resistance data as part of the fuel consumption study. Data on the Longitudinal coupler forces were used to compare the relative ability of various trucks to reduce rolling resistance and flanging forces, thus improving fuel consumption. The test program was designed to provide direct comparison measurements, wherever possible, with the Type I Truck tested earlier in TDOP Phase II. Seven Type II trucks were tested over the same test zones used during Type I testing. This report documents the changes to the instrumentation and equipment developed for Type I testing which were made for testing Type II trucks. Descriptions of the testing of each truck are presented, as are the procedures for data acquisition and reduction. Additionally, the report contains five appendices: Wheelset Calibration Data, Bearing Adapter Calibration Data, Type II Truck Test Plan and Procedure, Data Reduction Equations, and Transducer Location Measurement Data. The performance data gathered during testing will be used to formulate performance specifications for Type II trucks.
