Cresting the summit on UP's (formerly SP's) Palmdale Cutoff, a "traditional, post 1989" lashup of SP diesels, bolstered by three "untouched by SP paint" DRGW SD50s does the work.
DRGW 5508 W has been waiting for the SP 8008 to arrive off the mountain, to give them a shove to Donner Summit. The SD50 and B39-8 are good examples of Hi Tech power from the 1980's.
