EMD SD70MAC





Protype Information

The General Motors Locomotive Group (GMLG) Electro-Motive Division (EMD) SD70MAC is one of the most common locomotives plying the rails today. Originally introduced in late 1993 with an order for the Burlington Northern, the production now totals over 900 units, exceeding the combined production of the SD80MAC and SD90MAC locomotives by over 300 units.

Designed to be a solid locomotive to upgrade the Burlington Northern fleet, the SD70MAC has its origins in the SD60MAC design demonstrated on the BN.

At this time, the SD70MAC, in all of its versions, has been operated by six different railroads in a total of eight different paint schemes. The railroads that operate this locomotive span from East to West and from Mexico to Alaska! The locomotives are used to haul all kinds of freight, and even passenger trains (Alaska Railroad). For comparison, the SD80MAC has been operated in three paint schemes and the SD90MAC has been operated by three railroads in four paint schemes.

Model Information

All of these models will feature Kato's popular White LED Headlight, magnetic knuckle couplers, printed and lighted number boards, MU hose detail, a powerful five-pole motor with dual brass flywheels, and a DCC-friendly mechanism. Additionally, the models will feature walkway-mounted, lighted ditch lights! Handrails will be made of a paintable material so modelers can easily add white end railings.
These models will be equipped with all-wheel electrical pick-up and blackened metal wheels in trucks that replicate the HTCR Phase II trucks. (On the prototype, this truck evolved from the HT-C trucks found on the SD40-2 through SD60 and features radial steering capability).

Roadname Information
  • BNSF Executive Scheme
    As noted above in the Prototype History, the SD70MAC grew out of the EMD/BN SD60MAC demonstrators. The first SD70MAC was delivered to the BN in 1993 and established a standard locomotive type that remains a favorite on BNSF today. Even after the BN+ATSF=BNSF merger, the SD70MAC continued to be painted in the classy "Executive" scheme. BNSF #9837, manufactured in March, 1997, was the final new locomotive to be painted in the BN Executive scheme.
  • BNSF Heritage II Scheme
    The attractive BNSF Heritage II Scheme, also known as the "Premium Heritage Scheme," evolved from a special paint job applied to SD60M #9297. This locomotive was painted in a slightly different scheme on both sides, and based on employee input, the Heritage II Scheme was developed! The original Heritage I scheme is still applied to standard cab locomotives, however all wide cab locomotives now receive the Heritage II Scheme when repainted. Both the Heritage I and Heritage II Schemes are based on colors and logos from BNSF predecessor railroads.
  • Conrail
    An astute modeler will note that the road numbers Conrail assigned to their SD70MAC locomotives (4130-4144) fall neatly in line behind the road numbers assigned to their previously delivered SD80MACs (4100-4129). Conrail had placed an order with EMD for additional SD80MAC locomotives. But, then the NS & CSX merger/split with Conrail occured and the two new owners divided all locomotives right down the middle. Because this was a pending order, and CSX and NS were now in control, they were able to make order modifications. According to the Conrail Cyclopedia, Norfolk Southern converted their allotment of the second SD80MAC order into standard cab SD70 locomotives, while CSX converted their order into wide cab SD70MAC locomotives. Delivered in Conrail paint, these locomotives were built to the specifications of their future owners (note no red warning lights on CR SD70MACs). These were Conrail's final locomotives.
  • CSX
    On the CSX, the hard-working SD70MAC (known by the CSX as the SD70AC) is assigned to the Cumberland Coal Division. Delivered in 1997, CSX's original 75 locomotives were supplemented with an additional 15 from the Conrail merger. Prototype photos of CSX SD70MAC locomotives are available from the CSX Photo Archives.
  • Alaska Railroad
    When the Alaska Railroad ordered their SD70MAC locomotives for use on passenger and freight service, they were essentially an "add-on" to a pending BNSF order. In fact, the new Alaska Railroad paint scheme, which debuted on the SD70MAC, is based on the BN/BNSF Executive scheme! John Combs has put together an excellent website on Alaska Railroad history. Specific SD70MAC pages are here and here. The ARR SD70MACs were shipped by rail from Altoona, PA, through UP's Proviso Yard in Chicago, and all the way out to Seattle, WA for transfer to ship so they could be delivered to Alaska. During their trip across the lower 48 states, railfans flocked to the rails to catch a glimpse of ARR's newest power.
  • TFM (Kansas City Southern Affiliate)
    Officially known as Grupo Transportacion Ferroviaria Mexicana, TFM assumed control of Mexico's Northeast Railway in June of 1997. It was the first railway to be privatized under Mexico's National Development Plan. TFM operates the primary rail route in northern Mexico linking Mexico City with Laredo, Texas, where over 50 percent of US-Mexico trade crosses the border. Union Pacific and BNSF both interchange with TFM in Laredo, Texas (BNSF by way of trackage right over another NAFTA railroad, the Texas-Mexican Railway). A joint venture of Transportacion Maritima Mexicana (TMM) and KCS with the Mexican government, TFM is providing a critical link in Kansas City Southern's NAFTA Railway. The locomotives wear the same paint scheme as other KCS family railroads and are capable of operating on any NAFTA Railway line. Additional information about TFM can be found on the TFM corporate website.
  • Burlington Northern
    As noted above in the Prototype History, the SD70MAC grew out of the EMD/BN SD60MAC demonstrators. The first SD70MAC was delivered to the BN in 1993 and established a standard locomotive type that remains a favorite on BNSF today. As the last new locomotives purchased by Burlington Northern, the SD70MAC has a special place in US Railroad History.
  • BNSF Merger Scheme
    When the Burlington Northern and Santa Fe railroads announced that they would be merging, a special one-of-a-kind locomotive was released from the paint shop. This very special locomotive commemorated the merger in a unique way: the famous Santa Fe "Warbonnet" styling was painted using the attractive Burlington Northern "Executive" colors. The locomotive was a rolling "paint scheme merger!" As the only SD70MAC to ever wear a "Warbonnet" paint scheme, Kato is pleased to offer the locomotive in model form.
