The purpose of the Pennsylvania in obtaining this ascendency over the Baltimore and Ohio was to regulate the soft coal traffic. Already it had acquired dominating interests in the Chesapeake and Ohio, the Norfolk and Western, and other soft coal properties. These purchases were merely manifestations of that "community of interest" policy which at this time led several large systems to acquire interests in competing lines. Several of the railroad leaders of that time, notably James J. Hill and Edward H. Harriman, believed that if these great systems actually owned large blocks of stock in each other's properties, this common association would ipso facto end the competition that, if continued, would ultimately ruin them all. The Supreme Court had decided that the "pooling" arrangements which had so long prevailed among great competing roads violated the Sherman Anti-Trust Act; and the American public, which now was cultivating a new interest in railroad problems, believed that the "community of interest" plan was merely a scheme to defeat the Interstate Commerce Act and the Sherman Act and to maintain secretly all the old railroad abuses. These inter-railroad purchases therefore became so unpopular that the Pennsylvania sold its Baltimore and Ohio stock. At this time Edward H. Harriman of the Union Pacific, who had at his disposal vast funds of the latter property which he had obtained by the settlement of the Great Northern and Northern Pacific deal, decided to acquire control of a system of roads in the East in order to establish a complete transcontinental line in the interest of the Union Pacific. It was the theory that such a purchase by the Union Pacific would not defy the law or outrage the popular conscience because the Union Pacific, unlike the Pennsylvania, did not compete with the Baltimore and Ohio, but was only a western extension of that system. Harriman in August, 1906, therefore purchased nearly all the Pennsylvania holdings in the old Garrett property and thus obtained virtual control. At this same time the Baltimore and Ohio had been developing a "community of interest" plan on its own account. In the year 1903, it acquired a substantial stock interest in the newly reorganized Reading Company, which controlled the Philadelphia and Reading Railroad and the Philadelphia and Reading Coal and Iron Company. It did not obtain a majority interest but, with the Lake Shore and Michigan Southern Railroad of the New York Central system, it now controlled the Reading system. The Reading Company meanwhile had secured control of the Central Railroad of New Jersey, over the lines of which the Baltimore and Ohio reached New York City.
