(text taken from preface...)

The freight rate structures of the United States are largely a product of rate agreements between railways. A rate adjustment always involves a territory of origin and a territory of destination. So many rate adjustments have been made throughout the United States that the freight adjustment territories are numerous. These territories are technically described in territorial directories, information circulars, other territorial circulars, and freight tariffs.

However, this atlas of railway traffic maps is the first attempt to present comprehensive and accurate information concerning the freight rate territories throughout the country on maps prepared for that purpose. The freight adjustment territories are graphically portrayed on colored maps. The cost of producing these maps has been great, not only for engraving, printing, and editing, but also for the cooperation of a number of rate experts and railway traffic men. Moreover, the author has made for a number of years collections of the sources for the grouping.

These maps were prepared primarily to be used in connection with the LaSalle course in Traffic Management, and if applied in connection with the texts of this course the greatest benefit will be received from them. Independent of this course, however, the maps will furnish to traffic men and others a valuable reference work. The information contained on these maps is not to be found else where in any one publication for the sources are of widely varying character. Even where circulars, tariffs, etc., are available for looking up certain information, the maps will be found much more convenient and satisfactory for general purposes. But it is always necessary to consult current traffic publications for actual rating of shipments.

Where rates are shown on the maps, it should be thoroughly understood that they are given to indicate the general line of rates applying, and that there may often be changes in individual rates that are not shown on the map. Those familiar with the use of rates will thoroughly appreciate the impossibility of changing these maps in every case where individual rates are changed.

The grouping of territories for freight rates is subject to frequent minor changes and occasional material ones. For this reason it is impossible to show the exact current grouping of freight territories in a set of traffic maps. However, these maps are drawn with care and with as much accuracy as possible from traffic publications, and the general grouping does not often change materially. Moreover, every effort is made to correct the plates for material changes. For this reason the maps form a basis for the consideration of freight rate adjustments throughout the country. In order that a member may obtain vivid mental pictures that will aid him in understanding the rate structure, the colored maps are a necessity.

In addition to the value of the maps individually, several of them are complementary. For example, Map No. 4 shows percentage groups for rates from groups shown on Map No. 5, and Map No. 6 presents the percentage groups for rates to groups shown on Map No. 7. The complementary nature of certain of the maps is briefly set forth on the maps, and a more complete explanation is made in the treatises on freight classification and rates.
