This paper summarizes efforts to (a) obtain commodity- specific traffic volume data for all lines of the U.S. railroad system, (b) display those data on a national scale, and (c) analyze and better understand the absolute and relative distribution of the flow of these commodities. The procedure used to generate these data was a standard traffic assignment of historical traffic data contained in the Federal Railroad Administration (FRA) carload waybill statistics. For the purpose of this study, the 1976 waybill statistics report was expanded to match total annual terminating carloads by railroad and commodity as reported in the 1976 quarterly commodity statistics. Princeton University's Railroad Network Model, an enhanced version of the FRA network model, was used to assign these data to the (most likely) path actually traversed by each carload on the U.S. system. The traffic volume assigned to each link by direction of travel and commodity subgroup was accumulated over all carload records. Graphic displays of some of these accumulated volumes are presented.
