In 1920, Benjamin Franklin Jones Jr., chairman of the board of directors of Jones and Laughlin Steel, asked Tom M. Girdler (then Jones and Laughlin's General Manager) to take over the operation of the company's shortline railroads, which were inefficient and losing money. But United States antitrust law prevented Jones and Laughlin from directly controlling these railroads. Jones suggested that Girdler find a trusted associate to operate the shortline railroads, while Girdler secretly held the real decision-making power. Girdler turned to Charles M. White. White was promoted to operating manager of the Monongahela Connecting Railroad in 1920. He was soon given operating control of three other shortline railroads owned by Jones and Laughlin Steel, including the Aliquippa and Ohio River Railroad.
