EMD SD80/90

Prototype Information

The 80/90MAC is one of today's most powerful locomotives, seen throughout North America on Class I mainline railroads.
Weighing in at more than 400,000 pounds and with a length in excess of 80 feet, the 80/90 is one of the heaviest and longest single diesel locomotive in the world.
The 80/90MAC series was introduced by EMD in late 1995.
Conrail was the first railroad to receive the 80MAC in early 1996. As it would turn out, Conrail would be the only original buyer of this locomotive, even purchasing both of the demonstrator units. CSX and Norfolk Southern have since acquired these units.
The behemoth SD80 can generate up to 5,000 horsepower.
The maximum speed of the 80/90 is 75 mph.
To date, there have been three production "versions" of the SD90. The production version Kato has chosen to recreate is the 4,300 horsepower 9043.
Union Pacific, by far, operates the largest fleet of SD90 units. They have even applied different paint schemes to these units.
The 80/90 is equipped with the revolutionary radial truck, capable of reducing the angle of wear between wheels and rail. While keeping the wheels parallel to the direction of the track, this truck literally steers the locomotive through curves. This new technology improves locomotive adhesion and performance, eliminates several conventional truck components, extends locomotive component and track life and improves the ride quality.

  • While these models should be capable of operating on a 9-3/4" radius curve, it is recommended they be run on curves no smaller than an 11" radius to prevent the appearance of unrealistic overhang.
  • Modeling era: 1995 to present.
  • Included with model are number boards and front hand rails (to be installed by consumer). Also longer shank Kato knuckle couplers to be used if model is run on layouts with sharp radius curves.

Front end details include windshield wipers, ditch lights (working), plow, numberboards.

Side features include highly detailed trucks and EMD Builders Plates

A first for Kato: underframe detailing. A special piece is installed underneath the sill plate with details such the plumbing shown here.
