General Notes:

a. All units are equipped with larger radiators in a flared carbody to accommodate separate radiator cores for diesel engine jacket water and for aftercoolers.
b. All units are painted with UP's"Building America" slogan and U.S. flag decal, in memory of 11 September 2001.
c. The original unit that was to enter service as UP 3971 was instead, delivered as UP 4841 (2nd) to replace UP 4841 (1st) following that unit's return in late November 2002 to GMLG-London to repair a freeze-damaged engine block.
d. Order numbers (frame numbers) for these units are different from the builder numbers in that they include the build location, such as L for London and M for Mexico; UP 3779-3822 are order (frame) number L-20036559; UP 3823-3873 are order (frame) number M-20036559.

Notes:

1. UP 3833 was wrecked on 23 April 2009 at Oakwood, Texas; also wrecked and retired were UP 4479 and UP 9556.
2. UP 3971 is actually a renumbered and frame-restamped UP 4841 which was returned to EMD after freeze damage occurred to the engine block during delivery. To replace the UP 4841 as quickly as possible EMD selected another SD70M that had just been completed. This replacement SD70M was intended to be UP 3971, serial 20006271A-20, but when EMD numbered it as UP 4841 they restamped its frame as 20006271A-5. The original UP 4841 (1st) was repaired by EMD, renumbered to 3971 and restamped as 20006271A-20. Upon repair, UP 4841 (1st) was renumbered to UP 3971 and delivered to UP in late March 2003.
