General Notes:

a.	UP 31-53 were built using reconditioned truck and bolster assemblies from UP's retired 4500 GTEL gas turbine locomotives.
b.	UP 52 was delivered rated at 5,600 horsepower as a field test of a Cummins PT improved fuel system. The modification was removed and the unit de-rated to 5000 horsepower in October 1966.
c.	During 1969 a plan was devised to equip UP's U50 units with two GE 2800 horsepower engines (total rating of 5,600 horsepower) and renumber them to the 5600 class. Another proposal, also in 1969, was to strip all mechanical components from the locomotives, except the traction motors, equip them with large fuel tanks above the walkways, and use them as powered fuel tenders. Neither of these proposals went beyond the drawing board stage.

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.

General Notes:

a.	UP 70-83 were built using reconditioned GE 752 traction motors (with 74:18 gear ratio) from trade-in Alco FA and FB cab units. EMD used the designation 752E20A for these reconditioned traction motors. UP 84 was built using the reconditioned EMD D67B1 traction motors from wrecked trade-in UP GP9 159 and was equipped with 62:15 gearing.
b.	UP 71, 73, 74, 80, and 81 were originally equipped with 79:24 high speed gear ratio; later changed to 74:18 gear ratio.
c.	UP 82 was equipped for Radio Control (RC) operation in May 1968, serving as the control unit, matching UP 82B which served as the remote. All radio control equipment was removed from both units during July 1973 at Salt Lake City, Utah.
d.	Five additional DDA35 units were ordered by UP for delivery during 1966. The units were to be numbered UP 85-89. EMD assigned builder's numbers 29999-30003 to these five units. The order was canceled in lieu of SD40s. EMD did not use the builder's numbers for other locomotives.
e.	UP 70 was the first DDA35 to receive UP's "We Can Handle It" slogan, in late April 1972.
f.	During 1977 and 1978, UP began removing the sand boxes from the ends of both the DDA35s and the DD35s, replacing them with side sand boxes that were fabricated by UP's Omaha Shops, similar to factory-built sand boxes applied to the 6900 class DDA40Xs. The end sand boxes were removed to get dust and grit associated with the sand boxes out of the end control cabinets.
g.	UP 70-83 were built on EMD order number 7797.
h.	UP 84 was built on EMD order number 7798.
e.	Terry Kolenc reviewed his slides, and found that the following 9 units were in service during August and September of 1979: UP 71, 72, 75, 77, 78, 79, 80, 82, 83

General Notes:

a.	Built as Chicago and Illinois Midland 70-75. Purchased by UP in January 1995 to allow hump yard-assigned SD40-2s to return to freight service. The C&IM units were in national lease service, most recently on SP, who delivered them to UP at Houston in mid January 1995.
b.	UP 70-75 were initially assigned to freight service at North Little Rock, Ark., until all six units were reconditioned and repainted to UP. During April 1995, the units were formally changed to switch service and assigned to North Platte.
c.	Not equipped with dynamic braking.

General Notes:

a.	During 1977, UP began removing the sand boxes from the ends of the DDA35s and the DD35s, replacing them with side sand boxes that were fabricated by UP's Omaha Shops, similar to the factory-built sand boxes applied to the 6900 class DDA40Xs. The end sand boxes were removed to get dust and grit associated with the sand boxes out of the end control cabinets.
b.	As part of a reliability test program for the DD35 locomotives, three DD35s received modified electrical cabinets on the following dates. The modification forced the sand boxes from the ends, to the sides, similar to the sand box configuration used for the DDA40X Centennial units. April 1975 - UP 91B received GE electrical gear, inside sealed electrical cabinets, completed at UP's Omaha shops. February 1973 - UP 93B received a solid state control electrical cabinet on just its No. 2 end. At the same time, UP 93B was equipped with a Genisco transition programmer. February 1973 - UP 98B received solid state control electrical cabinets on both ends.
c.	UP 82B was equipped for Radio Control (RC) operation in May 1968, serving as the remote unit, matching UP 82 which served as the control unit. All radio control equipment was removed from both units during July 1973 at Salt Lake City, Utah.
d.	UP 97B was set-up at by UP at Omaha, Nebraska, on 22 September 1964.
e.	Terry Kolenc reviewed his slides, and found the following: The following 6 units were in service during August and September of 1979: 73B, 76B, 85B, 90B, 91B, 94B UP 90B still was without the running board sandboxes 85B still had the small numbers.
