Part of the original Santa Fe 1994 order, these SD75M’s are depicted as late in their life. Just before they were sold to PRLX, they soldered on looking beaten and battered, but still earning revenue for their owner. Renumbered to the 8200 class in the 2000’s, they eventually returned back to their original Santa Fe numbers again, but with BNSF patches.

PROTOTYPE SPECIFIC INFORMATION
Continuing upon the successful SD60-series, in 1992 EMD debuted the next step in locomotive evolution with the SD70-series. While outwardly similar at first glance to the SD60M, the D.C.-drive SD70M featured several external design refinements from the predecessor model. Battery boxes were relocated to the left-hand side walkway immediately behind the cab, a large, boxy forward traction motor blower housing replaced the angular version used on SD60s, the raised walkway duct on the left hand walkway was eliminated, and an intake for the rear traction motor blower on the left hand side of the carbody, directly under the rear radiator intake grill, was added.
Internally, the SD70 boasted improvements as well; a 16-710GB prime mover, rated at 4,000hp, was coupled to a new alternator design, the AR20. New D70TR traction motors were standard, and controlling all of this power and locomotive function was EMD’s new EM2000 microprocessor, which boasted more memory, twice the processing speed, and improved locomotive self-diagnostic capabilities compared to the processor suite used in the SD60. Even more revolutionary was the inclusion of EMD’s patented “Radial” truck design, the HTC-R. This design, which made its debut under EMD Demo SD60 #3, replaced the venerable HT-C truck, and is unique in its ability to shift, or “steer”, the wheelsets laterally through curves, resulting in greatly reduced wheelset and track wear, and coupled with the new D70TR traction motors and EM2000 microprocessor, greatly improved adhesion.
Continuing with previous practice, EMD built a set of Demonstrator SD70Ms, EMD 7000-7002, all equipped with the North American safety-cab (hence the “M” in their model designation), and decked out in an attractive gray, silver, and burgundy paint scheme. These units traveled all over North America, showing off the latest technology from EMD. Atchison Topeka and Santa Fe railroad requested a 4300 horsepower version resulting in the SD75M. As production continued, EMD incorporated their new “Whisper Cab” design resulting in the SD75I. The updated cab SD75I was purchased by Santa Fe successor Burlington Northern and Santa Fe, Canadian National, and the Ontario Northland.

Another great 📽️ video. Keep em coming!!
What's the difference between a EMD SD70M and SD75M other than increased in 🐎 horsepower 4,300hp in SD70M versus 4,500hr in SD75M?
Which brand of HO Scale track do you use?

[@Railfan-uf9mw]

I have an old Athearn genesis box from the 90s that the SD75Ms that came with a bulb and no dcc or sound and no ditch lights at all

I take it your work told you, that you can’t record during shifts anymore, is that why you don’t post any videos at work or on the trains?
