Charnley was the manager from 1911 to 1922 when he became secretary and manager for three years until he was succeeded, on his death, by his assistant, William Howard Oates in February 1925. Oates also died in office after only a year and was followed by Alfred Percy Ross, who combined the manager's role with that of Chief Engineer for a few years until July 1929. Sidney Burgoyne followed as manager in that December; he had come from the LNER and he returned there in 1932. The committee's last manager also came from the LNER; Gerald Leedham was designated "Acting Manager" from January 1933 until 1936, when he became "Secretary and Manager" until the committee was nationalised at the end of 1947.
