SP 5289
This loco was built in 1/1953 with EMD construction number 17158. It was built as a freight engine. It was painted in standard for the "tiger stripe" colors. This unit and sister SP 5288 did not receive a large ash can headlight, and they received an extra fifteen tons of ballast for some reason. Also, note that the construction numbers and unit numbers are out of sequence.
She was assigned number SP 2710 in the 1965 system renumbering.
All of the SD7's were renumbered as a group in 1973 to make room for new MP15 switch engines. This unit was renumbered SP 1410.
She entered the GRIP program and emerged as SP 1525 in 3/7/1980.
