Detailed Information

BNSF FEATURES:

Starting in the early 2000s, the Burlington Northern Santa Fe railway began repainting their former Santa Fe SD75Ms in the new Heritage II scheme. The locomotives had long, productive lives on the railroad in all types of mainline service, from unit coal trains to intermodal service out west, and have only recently begun to be retired.

CN FEATURES:

The Canadian National SD75Is, with their ribbed anticlimbers, Pyle early headlights, and raised walkways, are distinctive locomotives. The engines entered service in 1997 and continue as front-line power today.

CSX FEATURES:

After their service as EMDX leasers, CSX acquired the distinctive group of burgundy SD70Ms in the early 2000s. Instead of being immediately repainted, the units received a simple patch job on the side of the cab and continued in service for many years looking much as they did when new.

Included, painted, but not installed: Optional digital fuel gauge (added by CSX to most units sometime after acquisition. Placement varies- consult prototype photos).

NS FEATURES:

Norfolk Southern, always in the market for secondhand EMD power, acquired the three former NYS&W SD70Ms in late 2014. The new Thoroughbreds received a fresh coat of black and were renumbered 2797-2799. Since then, NS 2798 has been fitted with rooftop PTC antennas, a distinctive detail captured by our Genesis model.

#2797, 2799:

Sinclair & small can antenna installed with removable glue. Optional PTC antenna set included in box (it is believed that NS will retrofit these units with PTC in the near future).

UP FEATURES:

There is no shortage of variety within Union Pacific’s massive SD70M roster. In addition, the railroad has made many changes to the units over the years. Reflective yellow on the frame has replaced red, PTC antennas are becoming commonplace, and flags now grace the sides of many of the locomotive. This release of UP SD70Ms depicts units from the first order, with early (non flared) SD70M bodies. They have been observed working every conceivable assignment, from MOW & continuous rail trains, to mainline stack trains, to helper service on the former SP coast line.

PROTOTYPE HISTORY:

Continuing upon the successful SD60-series, in 1992 EMD debuted the next step in locomotive evolution with the SD70. While outwardly similar at first glance to the SD60, the D.C.-drive SD70 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 travelled all over North America, showing off the latest technology from EMD. Eastern giant Norfolk Southern liked what it saw, and was the first to order SD70s, but with a twist; instead of having them equipped with the increasingly popular (and soon to be standard) “M” cab, they opted for standard, or “Spartan” cabs on their initial orders. The first production SD70s, NS 2501-2506, built in 1993, were quickly followed by additional units; NS 2507-2531, also built in 1993, and NS 2532-2556, built in 1994. They could be found in a variety of assignments over the NS system, and even saw run-through service on connecting roads, such as Southern Pacific, making appearances on the West Coast.
