General Notes:

a. Total of 133 SP units went to UP at merger, numbered SP 8574-8706.
b. Rebuilt for SP by MK Rail in April 1994 through February 1995 from units in its own lease fleet (MKCX) and from units purchased second-hand by MK Rail from other sources, including National Railway Equipment (NRE, NRL, and NHL), Helm Financial (HLC and NHL), and VMV Enterprises (VMV); all of the former C&NW units (including all former CR, and most of the former BN units) were purchased from either VMV or NRE; in the case of NRE, MK Rail acquired units either directly from NRE, or with NRE acting as broker between C&NW and MK Rail; although owned by C&NW, many former CR units never got C&NW numbers.
c. SP 8574-8583, 8697-8706 (20 units) were rebuilt by MK Rail at Boise (Idaho) Locomotive Shop.
d. SP 8584-8625 (42 units) were rebuilt by MK Rail at Hornell (N. Y.) Car Shop.
e. SP 8626-8696 (71 units) were rebuilt by MK Rail at Mountaintop (Pa.) Locomotive Shop.
f. The rebuilding effort for all 133 units included new EMD Dash 2-style controls and electrical cabinet, a 3000-horsepower 16-cylinder engine, SD40-2-style radiator cores, and SD45-style nine-blade radiator cooling fans.
g. A total of 97 units (UP 2650-2658, 2660-2699, 2724-2733, 2735-2761, 2774-2782) were built as SD45s and retain their original carbody configurations.
h. UP 2650-2658, 2776 (ex SP 8574-8582 and 8700, 10 units) were built as SD45s and were rebuilt by MK Rail using carbodies that were made very similar to standard SD40s by replacing their components with comparable GP40-style components made available from MK Rail's completion of 10 GP40WH-2s for Maryland Area Rail Commuter (MARC), also during 1994, which needed the SD45 components for installation of auxiliary hotel electric power (HEP).
i. The former C&NW SD45s (33 units) were originally built without dynamic braking; the rebuilding by MK Rail included the addition of dynamic braking on these units.
j. The three former N&W SD45 and four former Southern SD45s got lowered short hoods in place of their original high short hoods.
k. UP 2659, 2700-2723, 2734, 2762-2765 (30 units) were originally built as SD40s and retain their original carbody configurations.
l. UP 2767-2772 (ex SP 8691-8696, six units) are former EL units, built as EMD SD45Ms (with carbodies similar to EMD's SDP45), and are 70 feet, 8 inches long, with 4900 gallon fuel tanks.
m. UP 2684, as UP 4634 (ex SP 8608) was the first of this group to be repainted to Union Pacific, completed on 28 August 1997.
n. MK Rail used the SD40M-2 model designation; UP uses SD40-2.
o. Assigned UP 4600-4732 in September 1997, three units renumbered, three units retired; assigned UP 2650-2782 in December 1999.
