U.S. Carloads & Weighted Intermodal Units, 1993-YTD
This graph represents measurements of loads in traffic of U.S. railcars (“Carloads”) and statistically adjusted U.S intermodal units (“Weighted Intermodal Units”).  Because, on average, an intermodal unit holds approximately 60% of a railcar’s volume, the measure of intermodal units has been weighted by a factor of (.6), bringing the two into an equitable and comparable standard of units.
