Nostalgia & History > a UP 60's view ... in 1983

Got this little group @ Salt lake City on Sept. 2, 1983 ..... the 62 was right there too, only it was nosing around w/the WP.

It's lenghty, but the history of these units is interesting ... the following info is from UtahRails.net

UP 60 UP 3634 UP 34 28 Jul 1980 2 Aug 1980 21 Dec 1983 1
UP 61 UP 3614 UP 14 14 Aug 1981 20 Aug 1981 21 Dec 1983 1
UP 62 UP 3615 UP 15 9 Sep 1981 12 Sep 1981 21 Dec 1983 1
UP 63 UP 3613 UP 13 16 Oct 1981 21 Oct 1981 21 Dec 1983 1
UP 64 UP 3608 UP 8 7 Dec 1981 13 Dec 1981 21 Dec 1983 1
UP 65 UP 3637 UP 37 2 Jun 1982 11 Jun 1982 21 Dec 1983 1

General Notes:
a. UP 60-65 were rebuilt from standard EMD SD45s by Morrison Knudsen at Boise, Idaho, during 1980 to 1982 as a test program using Sulzer diesel engines from Switzerland. Included in the program along with these six UP units were four ATSF SD45s, road numbers 5405-5408. The ATSF units were completed by Morrison Knudsen during mid 1981 and rebuilt back to standard SD45s, road numbers 5496-5499, by ATSF during 1984 and 1985.
b. The rebuild effort required extensive modification of the car body to accommodate the new engine. The most visible changes were an additional two inches of car body width along the hood sides, and a screen intake at the rear of the car body on the left (fireman's) side. Morrison Knudsen did the car body modifications on the first UP unit (UP 60/34). UP did the carbody modifications on the other five units in its own Omaha, Neb., shops prior to the units' moving to Morrison Knudsen at Boise.
c. Equipped with Sulzer 16ASV25R-30 engine and 62:15 gear ratio.
d. Union Pacific called these units SD45Ms; Morrison Knudsen used TE83-6S (Tractive Effort, 83,000 pounds, 6 axle, Sulzer).


1. All six units were retired on 21 December 1983, while stored at Council Bluffs, Iowa; sold to Precision National Corp., Mount Vernon, Ill., 29 October 1987; all six units were still at the Precision facility 10 years later when National Railway Equipment in November 1997 bought the assets of the bankrupt Precision National Corp; all six units were sold by NRE to CIT Group, Inc., rebuilt by NRE to SD40-2s (still in their modified SD45 carbodies) and leased to UP with the following new UP numbers:


Road New Date to UP
Number Number
UP 60 UP 4764 23 Sep 1999
UP 61 UP 4753 5 May 1999
UP 62 UP 4756 8 Jul 1999
UP 63 UP 4758 8 Jul 1999
UP 64 UP 4749 23 Apr 1999

Really good information. Anyone have roof photos of these units showing the exhaust stacks?

Now that's a proper air horn mounting!

Thanks for posting those great photos. I know it is not one of the ones in your photos, but here is a shot of the #17 leaving Eugene Oregon on the EUALY headed toward Portland.
