General Notes:

a. Total of 33 units, numbered UP 4733-4765; leased from CIT Group, Inc.; rebuilt from SD39s, SD40s, SD45s, and SD45Ms to SD40-2s by National Railway Equipment (NRE), Mount Vernon, Illinois, and Dixmoor, Illinois
b. The rebuilding to SD40-2s included qualification and repairs as needed of all components, upgrading of electrical controls to Dash 2 standards, and installation of a 3000-horsepower, 16-cylinder engine.
c. The SD39, SD40, SD45, and SD45M core units were owned by NRE previously; many were purchased by NRE in November 1997 when it purchased the assets of the bankrupt Precision National Corp. (PNC), including its rebuilding facility at Mount Vernon, Illinois; included in these assets were the former UP SD45 41 (retired by UP in January 1987 and sold to PNC in January 1988), and the Sulzer-powered SD45Ms (retired by UP in December 1983 and sold to PNC in October 1987).
d. UP's designation for these units is SD40-2.
e. Assigned UP 2783-2815 in June 2001 to avoid conflict with new SD70Ms in 4700 series.
f. Unit histories for UP 2811, 2812, and 2814 changed based on photographic evidence. (information from reports by Wolfgang Luth and Bill Miller, via email to LocoNotes discussion group on March 13 and March 15, 2003; Bill Miller has a photo of UP 2811 showing that it was a former SD45)
