Union Pacific Railroad

General Notes:

1. UP 222 was equipped with refrigerator enclosure, behind cab on fireman's side, in December 1982.
2. Not equipped with dynamic braking.
3. Built on EMD order number 5320.

General Notes:

1. UP 245-249 were leased to Camas Prairie Railroad at Lewiston, Idaho, throughout their operating career. Camas Prairie Railroad was a joint operation between Union Pacific and Northern Pacific (later Burlington Northern), with each road furnishing 50 percent of the required equipment for Camas Prairie operation.
2. UP 245 was built as an EMD GP9 demonstrator. Prior to being built, EMD planned on using the unit in demonstration service, then sell it at a reduced price. The locomotive was purchased by UP in May 1954 for, and leased to, the Camas Prairie Railroad.
3. UP 245 was built on EMD order number 6531; a check of the actual frame number in 1975 revealed an unusual five-digit number, 65311, which may have been the original EMD project number as a demonstrator locomotive. (View an image of the note from that frame check in June 1975)
4. After UP 245 was wrecked in mid-1977, it was replaced in dedicated Camas Prairie service by UP 293.
5. UP 246-248 were ordered for and leased to Camas Prairie Railroad. The units were ordered after the purchase of UP 245; all four units were delivered at the same time.
6. UP 249 was built as UP 204; renumbered from UP 204 to UP 249 in August 1955 for lease to the Camas Prairie Railroad. Originally, UP had selected number 244 as an additional unit for lease to the Camas Prairie, joining UP 245-248, but the Camas Prairie rejected UP 244 because it lacked dynamic braking. UP then selected 204, renumbering it to 249 in order to keep the units leased to Camas Prairie consecutively numbered. During 1978 the unit was positively identified as being the former 204; remnants of the original number could still be seen under the later number.
7. UP 246-248 were built on EMD order number 5347.
8. UP 249 was built on EMD order number 5321.

General Notes:

1. UP 256 was the last operating GP9 on Union Pacific. Its last day of service was in Omaha yard, on 8 August 1985; removed from service on 13 August 1985.
2. UP 261 was equipped with AiResearch turbochargers in May 1956 and was the third unit (UP 281 and UP 185B were the first and second units respectively) to be turbocharged in UP's turbocharging program of 1955-56. The turbochargers were removed in 1962 or 1963, with the unit being rebuilt back to a standard GP9. (Read more about UP's GP9 turbocharging program)
3. UP 281 was equipped with AiResearch turbochargers in December 1955 and was the first unit (UP 185B and UP 261 were the second and third units respectively) to be turbocharged in UP's turbocharging program of 1955-56. The turbochargers were removed in 1962 or 1963, at which time the unit was rebuilt back to a standard GP9. (Read more about UP's GP9 turbocharging program)
4. UP 283 participated in the GP9 turbocharging program by having extra openings cut in its car body as a test to investigate engine operating temperatures on a Roots blower-equipped, normal GP9, compared to turbocharger-equipped GP9B 185B. The temperature difference was not significant, but the openings remained throughout the 283's life. UP 283 was not turbocharged.
5. UP 250-262 were built on EMD order number 5361.
6. UP 263-294 were built on EMD order number 5362.
