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. \u003cbr\u003e\u003cbr\u003e 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. \u003cbr\u003e\u003cbr\u003e ATSF FEATURES:\u003cbr\u003e As-delivered appearance\u003cbr\u003e Small EMD plow\u003cbr\u003e Round deck mounted front ditch lights\u003cbr\u003e Large Sinclair antenna\u003cbr\u003e Early EMD trucks with hidden bearings \u003cbr\u003e\u003cbr\u003e Santa Fe's last official EMD order before the Burlington Northern Santa Fe merger, was for 51 SD75M's placed in 1994. The SD75M differs from the SD70M by a slight horsepower increase (4300 vs 4000), and an extra equipment bulge along the engineer's side of the body. They were delivered in Santa Fe's \"Superfleet\" scheme that was re-introduced in the late 1980s\/Early 1990s. \u003cbr\u003e\u003cbr\u003e SD70 SERIES LOCOMOTIVE FEATURES:\u003cbr\u003e Coupler cut levers\u003cbr\u003e Flexible Trainline and MU hoses\u003cbr\u003e MU stands\u003cbr\u003e Windshield wipers\u003cbr\u003e Lift rings\u003cbr\u003e Wire grab irons\u003cbr\u003e Walkway tread\u003cbr\u003e Sanding lines\u003cbr\u003e Lit signal lights and\/or beacons, if equipped\u003cbr\u003e Detailed fuel tank with fuel fillers, fuel gauges, and breather pipes\u003cbr\u003e Speed recorder unless noted\u003cbr\u003e EMD HTCR trucks, early with hidden bearings, or late with exposed bearings per prototype\u003cbr\u003e See-through cab windows and full cab interior\u003cbr\u003e Fine-scale Celcon handrails for scale appearance\u003cbr\u003e Body-mounted McHenry scale knuckle couplers - Kadee compatible\u003cbr\u003e DCC-ready features Quick Plug plug-and-play technology with 21-pin NEM connector\u003cbr\u003e Scaled from prototype resources including drawings, field measurements, photographs, and more\u003cbr\u003e Accurately painted and printed paint schemes\u003cbr\u003e Genesis driveline with 5-pole skew wound motor, precision machined flywheels, and multi-link drivetrain\u003cbr\u003e All-wheel drive with precision gears for smooth \u0026amp; quiet operation\u003cbr\u003e All-wheel electrical pickup provides reliable current flow\u003cbr\u003e Wheels with RP25 contours operate on all popular brands of track\u003cbr\u003e LED lighting for realistic appearance\u003cbr\u003e Heavy die-cast frame for greater traction and more pulling power\u003cbr\u003e Minimum radius: 18\" - Recommended radius: 22\" \u003cbr\u003e\u003cbr\u003e SOUND-EQUIPPED MODELS ALSO FEATURE:\u003cbr\u003e Onboard DCC decoder with SoundTraxx Tsunami2 sound\u003cbr\u003e Sound units operate in both DC and DCC\u003cbr\u003e Full DCC functions available when operated in DCC mode\u003cbr\u003e Engine, horn, and bell sounds work in DC\u003cbr\u003e All functions NMRA compatible in DCC mode\u003cbr\u003e Precision slow speed control\u003cbr\u003e Program a multiple unit (MU) lashup with lead unit only horn, bell, and lights\u003cbr\u003e Many functions can be altered via Configuration Value (CV) changes\u003cbr\u003e CV chart included in the box","brand":"Athearn","offers":[{"title":"Default Title","offer_id":42187370397778,"sku":"ATH-G71228-PRE","price":28.05,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0581\/3410\/2098\/files\/5kYrM7_8507e59d-ab81-4c82-9d37-73877f0f3a64.png?v=1761318269","url":"https:\/\/modeltrainstuff.com\/products\/preorder-athearn-genesis-ho-g71228-sd75m-atchison-topeka-and-santa-fe-220-280-49","provider":"Model Train Stuff","version":"1.0","type":"link"}
