s and secondary main lines. Santa Fe's aging fleet of F7 units were approaching retirement age in 1970. These units were remanufactured into switchers and named CF7. Santa Fe used them for a decade and sold many of them to short lines around the states. Many of those were still being used as of 2003.

Afterlife

Changing philosophies regarding motive power expenditures led the Santa Fe to begin trimming its CF7 roster in 1984. The majority of the locomotives were sold for as little as $20,000 to short-line and regional railroads such as the Rail Link, Inc., the York Railway, and the Maryland & Delaware Railroad (6 were involved in wrecks and 3 others sent directly to the scrap yards), though

were among the major initial purchasers. By 1987, the company had divested itself of all of its CF7s. These locomotives have well withstood the test of time, and have long outlived their projected service lives, two times, both as original F-units and as rebuilds. As of 2017, all CF7s still in service are over 60 years old.

Preservation

Several CF7s are preserved and operational on many tourist and local trains. Among them are: #2546 at the Kentucky Railway Museum, and #2571 at the Oklahoma Railway Museum,
