| DENVER CO Oct 20 1977 -- Colorado and Southern-Santa Fe SW12 157 slowly heads for a cut of cars while performing switching duties. The unit is jointly operated by C&S and Santa Fe. EMD built it as SW1200 157 (s/n 25007) for C&S in February 1959. It was renumbered as SW12 252 in August 1979, became Burlington Northern 252 in 1982, became BNSF 3520 in April 1989, then BP Products North America ARPX 458 and then became BP Amoco Chemical Co BPOX 458. A big thank you for LocoNotes contributors Don Ross and Russ Strodtz for pointing me in the right direction to identify this unit.
