DETERMINATION OF OPERATING COSTS FOR FOUR RAILROAD FREIGHT CAR COMPONENTS BY SIMULATION MODELLING--VOLUME I

This report describes an investigation, performed under Task VIII of the Track - Train Dynamics Program, concerned with costs to operate (maintain and acquire) freight car components. Four components are considered: wheels, roller bearings, bolsters, and side frames. The technique used is dynamic simulation cost modelling (SCM). Volume I describes the technique and its three elements: the schematic diagram which describes component usage, the capabilities of the computer program which implements the diagram, and the required input data set. A preliminary input data set for each of the components and the corresponding approximate results are given. These results are for the reference (present time) composite national railroad system. This reference case gives the current usage of the components and the costs to operate the components. The cost sensitivity analyses, giving the effect of each parameter on the system cost, are also given.
