Detailed Information



Purchased in 1997, BNSF's only order of SD75Is was numbered 8276-8301, and they bore a close resemblance to the SD75Ms, which came before. Perhaps the biggest difference was the use of the isolated cab, seen as rubber gasket running down the side of the nose. This was thought to increase crew comfort by isolating them from the noise and vibration of the engine compartment. All of the locomotives were delivered in the Santa Fe Warbonnet scheme, but with large "BNSF" letters on the side-creating a mix of old and new that was particularly suited to these locomotives. Their primary assignment was coal traffic, although it was not uncommon for them to stray westward on other types of BNSF trains.

These SD70Ms previously wore the EMD demonstrator scheme of burgundy with a black underframe. When they were acquired by CSX, they ran for several years before being repainted in the then-current YN2 "Bright Future" scheme, which they are depicted with here. In addition, several of the units received special names adorning the sides of the nose-all were significant places in Florida, where the SD70Ms worked frequently.

    Painted in an easily recognizable scheme, these EMD lease units wandered all over the western railroads in the mid 1990s to the 2000s. Both Southern Pacific and Union Pacific leased them in the '90s, and it was not uncommon to find them on nearly any type of train, so they are appropriate power for most western modelers of that era. Later on, the units went to CSX, but received only a patch and continued to run for several years in their leasing colors.

    Representing the only SD70Is built, Canadian National ordered 26 of these locomotives in 1996. They were all delivered painted in the single stripe scheme, featuring bold orange ends and a large "CN" adorning the side of the hood. Typical of many Canadian locomotives, they have several distinctive spotting features, such as early-style Pyle headlights mounted in the nose, ribbed front and rear anticlimbers, and the CN specified fuel tank with auxiliary waste oil retention tank. Now approaching their 20th birthday, these engines are still mainline power on the CN, and can often be found working in multiple with most other types of power, including GE Dash 8 & 9s, and EMD SD40, SD60 and SD70 series.

    Representing their as-delivered appearance, these SD70s were built for the NS by GMDD in London, Ontario, in 1993/94. With most railroads opting for the wide-nosed safety cab for their new locomotives at this time, these NS units are unique with their standard EMD Spartan Cab-making them look much like the SD60s before. However, they have several features that set them apart, such as the Integrated Cab Electronics (ICE) bulge on the fireman's side of the nose, and HTCR radial trucks. Additionally, NS fitted them spare knuckle baskets on the walkway and dual fuel sight glasses. They were a common sight pulling intermodal and unit trains, in multiple with other NS and/or Conrail power.

    Note: As delivered, these NS SD70s were not equipped with a toilet access hatch on top of the nose; however most were retrofitted after a few years. We have included this part, prepainted in the box, for modelers to install at their discretion.


    Union Pacific was the largest purchaser of the SD70M model, with over 1400 eventually on the roster. With such a large group of locomotives, there are many variations between orders.

    The 5127-5231 number group-some of the last that were produced for the UP-are depicted here. These late production units feature several key characteristics including 4-panel flared radiators (which have never before been offered before), phase II cabs, & late profile fuel tanks.

    UP #4014 FEATURES:

    Union Pacific #4014 was, until recently, just another SD70M. Part of a group of 75 built in 2000, the unit is an example of the earlier production body without flared radiators. On April 28, 2014, Union pacific's other 4014, the Big Boy, was sent on a trip up Cajon pass on its way to restoration in Cheyenne, Wyoming. Selected as the locomotives to pull this special train were SD70M's #4014 (to match the Big Boy's number) and #4884 (the Big Boy's Whyte notation wheel arrangement.) With the 4014 leading, the trip was made to much fanfare, and the unit became an instant celebrity.

    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.
