    Scope and Content of Collection

    This collection contains files of Southern Pacific technical engineer Jack Davis pertaining to the SP's handling of freight involving oversized material, known as "high and wide loads." It includes Jack Davis' common record book (which contains useful information for completing a restrict movement form), correspondence about the construction of the R 60 line and its impact on SP's Placerville Branch, a Vice President and General Manager's letter about compliance with rules for derails, exhibit files for legal cases (which include reports requesting handling of oversize material and tables, route configuration, restriction notices and railway clearance files with restrictions), SP line clearance circular No. 83 (July 1983), procedures on how to handle high and wide loads between Roseville and Sparks, and a profile of Summit, California. The railway clearance program file contains abbreviations and a glossary to messages employed by the clearance program and a manual for the Atchison, Topeka & Santa Fe computerized clearance system. Files also include safety brochures, an SP technical employees seniority roster for the Salt Lake District (January 1, 1986), telegrams about high and wide loads, and track construction requirements from the California Public Utilities Commission. Arranged alphabetically by file name.
