The E8/9 was built by EMD (Electro-Motive Division of General Motors). The Pennsylvania Railroad acquired these locomotives from 1950 through 1952. They were equipped with 2250HP engines, and classified by the PRR as EP22 (EMD, passenger, 2200 horsepower). The Fallen Flags web site is the source of the prototype photo of #5891 on the right here. There are some resources in books, namely "Pennsylvania Railroad", 1997, MBI Publishing Company, ISBN 0-7603-0379-7, pp 2, 25, 78, and "The History of the Pennsylvania Railroad", 1995, SmithMark Publishers, ISBN 0-8317-3787-5, pg 110.

These Kato models shown below are great locomotives. Their engines are relatively quiet. They are long, though, so watch them in curves with tight radii. The first run was released in 1993 and the second run was released in June of 2000. The first photo below of #5802 with all the modifications applied. The other two photos are of the original models as released in 1993 and 2000, respectively.
