ABSTRACT: The overall objective of the TDOP Phase II project is to characterize the behavior of existing trucks (defined as Type I trucks) and to generate performance and test specifications for new truck designs (referred to as Type II trucks). The purpose of this document is to report on the progress to date of TDOP Phase II. The report summarizes the methodology employed to develop performance and test specifications and the rationale used for selecting seven Type II trucks for field testing. The Interim Report also discusses preliminary conclusions reached in several economic areas, including car and truck maintenance costs, fuel consumption, and rail wear in curves. Further, the report describes on-going field test programs (the truck performance testing and wear measurement programs) and the completed Friction Snubber Force Measurement System test program. In the analysis area, an assessment and validation of 17 computer simulation models of freight cars is discussed in detail. The Interim Report concludes with a description of the work-in-progress for a Type I truck performance characterization.
