Ward Kimball was one of Disney's famed Nine Old Men and shared Walt Disney's passion for trains. Like Disney and Johnston, Kimball also had a backyard railroad. However, Ward's Grizzly Flats Railroad featured two full-scale Baldwin narrow gauge locomotives running on 500 feet of track.
In 2005, Disneyland honored the talented artist by naming their newly acquired locomotive the Ward Kimball (Engine No. 5).
