    Which engine did the SD50 have 645 or 710?

    Looks like it has a 645F.

      The SD50s stretched the 645 to the limit. I have read much about EMD's failure to keep up with GE and throwing the SD50 into the 'fray' as a stopgap until the 710 was developed fully. It seemed most railroads disliked the 3500hp 645, but some really made it work quite nicely. We still see quite a few GP50s on the BNsf up here-abouts.

        CN still have their SD50Fs, and they seem to work fine. I have heard that the 645 in the 50 series was more maintenance intensive than its predecessors.

        Inside every GE is an Alco trying to get out...apparently, through the exhaust stack!

          The SP-DRGW group of SD50s seemed a bit shy when first delivered. Now I seem to see them most in transfer drags or heavy yard switching at Colton. I never did see them all that commonly on the mainline outside of California. They certainly were a rare sight in the Southwest. Anyone else have anything to add? Were they more common elsewhere in mainline service?

            Tom,

            SP used the SD50's as helper sets over Tehachapi Pass. I remember seeing them in all their blackness. Helper sets over Tehachapi always ended up being black, no matter what color they started out as.
