Material Classification: Recommended by the Railway Storekeepers' Association

"Material Classification" is a technical publication written in the early 20th century. The document serves as a guide for the classification and management of materials across railroads under federal control, specifically produced for the United States Railroad Administration. It is likely aimed at railroad professionals, particularly those involved in finance, purchasing, and inventory management, outlining categories and specifications for various railway materials and supplies. The opening of the publication presents an introductory section from the Director General of Railroads, emphasizing the need for a systematic classification of materials for maintenance, equipment, and transportation. It provides a framework for categorizing items into distinct classes and subclasses necessary for the efficient management of railroad resources. Specifically, it details the comprehensive classification system starting with broad categories, such as maintenance materials and equipment, and includes a variety of items ranging from track fastenings to locomotives, thereby establishing a structured inventory system for operational efficiency.
