Abstract
IN RECENT YEARS claims for damage to freight shipments have been steadily increasing, and such claims currently cost the railroads of the United States over 100 million dollars annually. Some of this damage occurs during the various classification processes. There are two main types of classification yards; namely 1. flat switching and 2. gravity. The gravity yard is the type of yard dealt with in this paper.
