The Timken "Four Aces" was built by the American Locomotive Co. in 1930 under the auspices of the Timken Corporation for the purpose of demonstrating the importance and use of roller bearings on all axle journals of steam loco*motives. Rather than rebuild an existing engine, a new one was built so that it could be impartially tested by any interested railroads. Fifty manu*facturers of locomotive appliances co-operated with Timken in the proj*ect, with a 4-8-4 type being chosen, this to have a top speed of 85 miles an hour.
