Norfolk & Western Railway President Robert B. Claytor will become chairman and chief executive officer of the Norfolk Southern Corp. when Norfolk & Western and Southern Railway merge next month.

Harold H. Hall, now president of the Southern Railway, will become president and chief operating officer of the Norfolk Southern, which will have headquarters in Norfolk.

Richard H. Dunlop will succeed Claytor as president of the N&W. Edward B. Burwell will succeed Hall as president of the Southern. Day-today operations of the two railroads will continue to be separate.

Named as executive vice presidents of the merged rail lines were Arnold B. McKinnon, marketing; George S. Paul, administration; John S. Shannon, law, and John R. Turbyfill, finance.

Thirteen vice presidents, each supervising major departments of the Norfolk Southern, will report to the executive vice presidents.

Merger of the N&W and the Southern was approved by the Interstate Commerce Commission on March 25.

The N&W said it is expected that some, but not all, of Norfolk Southern's officers will be transferred to the headquarters of the holding company in Norfolk this fall, when office facilities are ready for occupancy in the Virginia National Bank building.

Until that time, affairs of the two railroads will be conducted from the N&W headquarters in Roanoke and Southern headquarters in Washington.
