The SDP40Fs were reconditioned in the railroad's San Bernardino, California shops to the designation SDF40-2 for use as freight locomotives. Santa Fe replaced the hollow HTC bolsters with conventional HTC bolsters, converted the below-frame combination fuel/water tank to an all-fuel tank, removed the above-frame water tanks (replacing these with concrete ballast) and used the engines for nearly 15 years. They were also given front steps and platforms. Their noses were notched after a second maintenance shop visit in order to improve boarding access. In exchange, Amtrak received 43 smaller locomotives for use in switching service.
