General Notes:

a.	UP 8000-8002 were built as UP 3240-3242; converted to high speed 8000 class units in 1976; converted back to normal SD40-2s between June 1980 and May 1981.
b.	UP 8003-8034 were built new as UP 3243-3274; converted to high speed 8000 class units in 1976; converted back to normal SD40-2s between June 1980 and March 1982.
c.	The original order for UP 8003-8034 (EMD 73661, UP 3243-3287) included UP 3284, 3285 which were renumbered to UP 8044, 8045 in May and April 1976; both units were renumbered back to their original numbers in August 1976 after UP decided to accept the new deliveries of SD40-2s in the new 8000 class rather than to continue to renumber SD40-2s already in service.
d.	UP 8035-8064 were renumbered to UP 3305-3334 between June 1980 and March 1982.
e.	UP 8065-8074 were renumbered to UP 3400-3409 between June 1980 and March 1982; originally to be delivered as UP 3400-3409, but in late April 1977, UP asked EMD to deliver the units with 8000-series numbers.
f.	UP 8075-8099 were renumbered to UP 3584-3608 between June 1980 and March 1982.
g.	Equipped with high speed 59:18 gear ratio.
