UP Omaha GP20 335
Title:  UP Omaha GP20 335
Description:  UP Omaha GP20 335 at Council Bluffs, Iowa on an unknown day in October 1963, Kodachrome by Dick Rumbolz, Chuck Zeiler collection. Number 335 was built as UP GP9 335 in September 1957 (c/n 23691), retired June 15, 1981 and sold to Precision National Corporation. In October 1965 it was sent to EMD for application of EMD's own turbocharger, becoming one of 27 UP cab GP9's so upgraded to 2000 horsepower by EMD. Please see: http://utahrails.net/articles/up-gp9-turbo.php

Threre appears to be a conflict between the photo date and the upgrade date, and I will research that, but I stand by the photo date based on the Kodak date stamp and the pencil notations on the slide frame.

UP GP9m 340
Title:  UP GP9m 340
Description:  Union Pacific Railroad GP30 724 and GP9m 340 at Kansas City, Missouri on an unknown day in April 1980, Kodachrome by Chuck Zeiler. Number 724 was built in March 1963 (c/n 28204), retired in April 1982 and sold for scrap. Number 340 was built in September 1957 (c/n 23696) and was retired April 2, 1981. It began as a normal 1750 hp GP9, but between 1962-65 the UP installed EMD turbochargers on 55 of its 300-series GP9's, creating 2000 hp GP9's, or, as they became known, Omaha GP20's. The Omaha GP20's also received large 2400 gallon fuel tanks and some were further modified with heaters in the tanks to allow them to use Bunker C fuel oil. Those locomotives were converted back to diesel fuel in the 1970's. However, as the conversion back to diesel was taking place, the UP was adding 2400 gallon tanks to some of the un-converted Omaha GP20's as well as to some of the un-turbocharged GP9's. So, while number 340 shows a larger fuel tank, it is unknown if it was ever converted to burn Bunker C fuel.

UP GP9m 340
Title:  UP GP9m 340
Description:  Union Pacific Railroad GP9m 340 at Kansas City, Missouri on an unknown day in April 1980, Kodachrome by Chuck Zeiler. Number 340 was built in September 1957 (c/n 23696) on EMD Order 5552 and was retired April 2, 1981. During June 1964 this locomotive was equipped with an EMD turbocharger at UP's Omaha Shops, giving this unit and at least 54 other GP9's the moniker "Omaha GP20", and creating a 2000 hp GP9. The program began in early 1955 with the application of AiResearch Model T-30 turbochargers to four GP9's at UP's East Los Angeles Shops (four turbochargers per unit). The four units were sent out for road testing, and after modifications, the program was moved to Salt Lake City in September 1956. By 1959 the program was moved again to Omaha, and nine more GP9's were turbocharged (bring the total to 13). At the same time, ten nearly new GP9's of the 300-series were turbocharged using Elliott Company products, and three GP9's were sent to La Grange for application of EMD's new turbocharger. Later, the UP sent six more GP9's to EMD for the same modification. Between 1962 and 1965, 55 more GP9's in the 300-series were turbocharged with the EMD product by the UP at Omaha, and the AiResearch and Elliott modified units were de-turbocharged and converted back to normally-aspired GP9's. Number 340 was modified in June 1964, and at the same time a 2400 gallon fuel tank was installed, forcing one of the twin air reservoirs to be re-located to the front of the locomotive. Some of the turbocharged GP9's were also modified to burn low grade Bunker C fuel oil, and heaters were installed in the fuel tanks to permit efficient fuel flow. It is unknown exactly which Omaha GP20's were modified to burn Bunker C fuel, but the telltale sign is open metal grating on the walkways along the long hood to dissapate heat, and 340 shows signs of that. During the 1970's, Bunker C fueled locomotives were converted back to diesel due to rising costs of that fuel. The full turbo story is at this link: http://www.utahrails.net/articles/up-gp9-turbo.php

Number 972 was built in May 1956 as GP9 254 (c/n 21206), rebuilt ijn October 1972 as GP20 972. The GP20 designation is a bit mis-leading; an EMD GP20 was powered by a 16-567D2 turbocharged prime mover, whereas a MILW GP20 was powered with a non-turbocharged 16-645E prime mover, same as EMD's GP38. All produced 2000 horsepower.
