General Notes:

UP uses the "45" in its C45ACCTE designation to distinguish its Tier II units from its AC4400s (C44ACCTE vs C45ACCTE). The 45 in UP's model designation does not signify horsepower.
UP 5353 has UP's "Building America" slogan and U. S. flag in a different position; the flag is centered on the long hood, with the slogan and UP logo medallion (shield) located immediately behind the cab on both sides. (information from Ken Larson, via email to LocoNotes discussion group, August 16, 2005)

Notes:

UP 5353 was a single-unit order.
UP 5453 was the last new GE delivered with red frame stripe.
UP 5454 was the first new GE delivered with yellow frame stripe.

General Notes:

UP's model designation is C44ACCTE; GE's designation is AC4400CW.
The delivery of 15 units (UP 5711, 5714, 5715, 5716, 5721, 5722, 5726, 5730, 5731, 5735, 5736, 5739, 5742, 5747, and 5748) was delayed from the March and April 2001 time frame to allow former SP/SSW GP60s in the 5700 series to be renumbered to their new 1900 series numbers; these remaining 15 units were originally to be delivered in the last quarter of 2001, but an economic slowdown forced a delay until February 2002, making the 2001 delivery quantity only 55 units, instead of the planned full quantity of 70 units.
The builder's numbers are not in sequence for all units due to the actual delivery sequence being in random order to allow for existing GP60s to be renumbered. Interested observers are invited to compare builder's dates and delivery dates for the new GEs, along with renumber dates on the GP60s for a better understanding of what happened.
All units delivered during 2002 (UP 5770-5864), plus the 15 delayed-delivery units from 2001, are painted with UP's "Building America" slogan and U.S. flag decal, in memory of 11 September 2001.
In February 2002, GE changed the style of the panel covering the inverters on the fireman's (left) side of these new units; up to and including UP 5813, the panel was flat; with UP 5814 and all later units, the panel has X-pattern bends for strengthening. (information from Don Zimmerman)

Notes:

UP 5836 was wrecked on 19 June 2002 at Keith, Nebraska; retired due to wreck damage. (Extra 2200 South, Issue 124, page 24)

General Notes:

UP's model designation is C45ACCTE; GEs designation is ES44AC.
UP uses the "45" in its C45ACCTE designation to distinguish its Tier II units from its AC4400s (C44ACCTE vs C45ACCTE). The 45 in UP's model designation does not signify horsepower.
UP 7901-7905 are equipped with Electronically Controlled Pneumatic (ECP) brakes.

Notes:

Jeff Thoreson reports that when he first saw UP 7800 and 7801 just before the two locomotives were to be tested on Norfolk Southern adjacent to GE's Erie factory on March 1, 2008, the locomotives' builder plates both showed a build date of February 2008. When he saw the locomotives again on March 17 and 19 about to be delivered, the build dates had been changed to March 2008.
