SP 6007B
This cabless booster loco was built in 7/1948 with ALCO-GE construction number 75609. She was painted in the SP's Daylight orange and red as a passenger engine. She was delivered as part of an ABA set which included matching PA-units numbered SP 6007A & 6007C, but they were never drawbar equipped.
She was renumbered to remove her alpha suffix along with many other SP E-units and F-units in 1949. She became the SP 5912 on 10/19/1949.
At some point in the late 1950's or possibly early 1960's she was repainted into the newly adopted grey and red "bloody nose" scheme for all locomotives regardless of passenger or freight assignment.
She was retired sold to GE on 07/05/1963 for scrap.
