Freight Traffic Density 1930-31
Scope and Contents
The Transportation Library's collection of H. H. Copeland and Son's maps consist of 74 maps and tables on U. S. railways dating from the early 1930s to the mid 1950s. H. H. Copeland and Sons were an investment house, in existence from the late 19th century to at least the mid 1950s.
H. H. Copeland and Sons ordered the compilations for the maps and tables to support their own business interests and would not allow the items to be copied. This is probably why there are only a handful of Copeland maps scattered around the country. The Transportation Library's holdings are significant enough to draw researchers from all over the country.
The Copeland maps consist of traffic density maps and tables on ton miles, freight density and traffic distribution and other railway related tables and calculations.
