In 1906 a royal commission was held to investigate allegations raised in parliament by Harry Bolton that Short and George Julius had engaged railway tradesmen to do work for them on government time, and that the Commissioner, William George, had colluded by suppressing the information.
The commission found the allegations baseless.
In 1907 Short succeeded George, first as acting Commissioner, and in July 1908 to the substantive position, and made permanent in 1913. He retired on 30 June 1919.
His tenure of eleven years was notable as a period of great expansion (190 miles of line in 1896 to 1,516 in 1904), but he created considerable resentment in the goldfields area of Kalgoorlie and Coolgardie when some passenger services were cancelled. His successor, Colonel Pope, was more diplomatic, and able to implement changes without arousing unnecessary resistance.
