During construction of the Central Pacific and Southern Pacific Railroads and their early subsidiaries, the federal government
appointed commissioners to inspect the work prior to the awarding of subsidies. Operating under the auspices of the Secretary
of the Interior, the commissioners reported on the progress of construction, condition and valuation of the line and appurtenances,
facilities, and equipment in use, and made recommendations for improvements, route changes, etc. The investigations of the
Central and Southern Pacific and their subsidiaries were carried out in sections generally of forty mile increments.
