Tom Storey, whose father was a fireman for the Northern Pacific railroad, grew up fascinated by steam locomotives and spent many hours as a child making drawings of steam engines. This interest continued into adulthood and when he retired from Pacific Northwest Bell Telephone Company in the 1970s, he set out to construct a working model of the Timken locomotive 1111 (also known as "Four Aces")he had seen as a boy. He began to gather and trace the drawings in this collection in 1975. He met fellow Timken model enthusiast Roy Johnston and based many of his mylar tracings on his prints. Tom died in 1984, and his family completed the few unfinished tracings so they could be used by modellers to build "Four Aces".
The Timken "Four Aces" steam locomotive was created and assembled by the American Locomotive Company in 1930 as a demonstration unit for Timken Roller Bearing's new kind of roller bearing. Several railroads, including the New York Central, the Chesapeake & Ohio,the New Haven, and the Pennsylvania Railroad used "Four Aces" to power trains on freight and passenger runs. Its sealed roller bearings performed very well compared to locomotives assembled with plain roller bearings. In August 1931, the locomotive went to Northern Pacific, which purchased it in Febrary 1933. It was retired in August 1957.
