4-48. Administration of safety-appliance laws. Issue of instructions and regulations relative to inspection and tests of railway locomotives and rolling stock. By Executive Order No. 1002, dated January 6, 1909, railways operated and cars used within navy yards, arsenals, etc., were specifically placed within the purview of the safety-appliance laws. This provision, however, was amended by Executive Order No. 1750, dated March 19, 1913, whereby the application of the safety-appliance laws to navy yard equipment was made discretionary with commandants, their action to be subject to the approval of the Chief of the Bureau of Yards and Docks. The instructions of the Interstate Commerce Commission are, therefore, not binding in the premises, but are nevertheless valuable for technical guidance. Publications of particular interest are "Safety appliance laws," with instructions for inspectors, and "Laws, rules, and instructions for inspection and testing of locomotives and tenders and their appurtenances."
