Harrison said he plans to implement the tightly scheduled operating model he used at CP and Canadian National railroads to reduce costs and boost profits. Hilal, whose hedge fund owns 4.9 percent of CSX's stock, praised the board for agreeing to the changes. "The board is united behind a shared goal — creating value for shareholders and all stakeholders by implementing the precision scheduled railroading model at CSX," said Hilal, who is slated to become CSX's vice chairman. But the changes won't be assured to happen until after the railroad holds its annual meeting.
