The following timetable details the progression of these 3600 horsepower behemoths through a succession of eleven (!) different incarnations. The vertical axis is an approximate timeline, with each row in the chart representing a particular incarnation. Each of the right-hand columns represents a particular locomotive as it passed through time. Most of the units skipped one or more incarnations; these are represented by vacancies {"miss"} in the particular row involved. At the end, the ultimate disposition of each of the units is detailed; all of the remaining units have been donated to various museums by the BNSF. As more details become available, I will update the chart If you can help with this effort, please E-MAIL me.
The FP45 units were originally delivered with
ATS shoes (that permitted operation at passenger train speeds) steam generators,
and a "can" antenna centered on the cab roof. The steam generators
were all removed as the units transitioned to primarily freight duties.
When the units were rebuilt to SDFP45 in the early 1980s, they left the
shops with modifications to their headlight arrangements, new rooftoop
air conditioners, rotating beacons and Sinclair antennas on raised ground-plane
platforms. Additional changes occurred as the units were shopped duting
the 1980s; this included addition of the "baby Sinclair" antennas (they
communicate with the "FRED"
units that replaced cabooses at the end of most of Santa Fe's trains),
and movement of the horn toward the rear of the unit. As a result
of these changes taking place gradually during the 1980s, each unit took
on a diferent "personality" during that period, and railroad modelers need
to have photos of each unit they model if they want to make sure that they
capture the locomotive's unique look for the period. For example,
look for the units that received yellow air conditioners as you peruse
the photos. (These shop swaps have been going on for quite some time--there
is a photo from 1968 of an SD45 sporting a silver radiator fan from an
original 100-class FP45 that can be found in Joe McMillan's Route of
the Warbonnets.) If you find a photo with a blue fan on a silver
unit, let me know also.
