First off, the SD70I is the same as the SD70M, but with an isolated cab (read: more expensive). SD75M/I would also be more expensive, and when UP was placing the order, the unit availability the 75s had shown with CN and ATSF was less than the SD70s. UP also inherited a good number of them from SP. So in the interest of lowest cost per hp/mile and unit standardization they chose the SD70M.

you consider 25 units a "good number"??
thats all they got from SP
The same can be said for the DRGW SD50's... a 17 unit order, 7 of which went to SP and finally to UP, you don't see me making a big deal about them...

you consider 25 units a "good number"??25 may seem small in comparison to UPs later 1000 unit order, but 25 locomotives are not chump change. They represented a sizeable investment, especially for a cash strapped SP at the time. They were purchased right before the merger, so one could logically speculate that these might have been some icing on the cake for the UP folks. I would venture to guess that SP would have bought more SD70s had there been more money available.

On the other hand, they aquired 101 C44-9W's shortly after the 25 SD70M's. Now in comparison that is a good number. The SP SD70M's were aquired in 1993, so they were not the "icing on the cake" for UP.you consider 25 units a "good number"??25 may seem small in comparison to UPs later 1000 unit order, but 25 locomotives are not chump change.

Compared to the quantities of other locomotive models on the SP roster and the total number of locomotives they owned, 25 SD70M's wasn't a "good number". On the other hand, they aquired 101 C44-9W's shortly after the 25 SD70M's. Now in comparison that is a good number. The SP SD70M's were aquired in 1993, so they were not the "icing on the cake" for UP.Not to mention the nearly 300 AC44CW's or 200 GP60's.
