Lightweight Laptop for Students - N SD90/43MAC UP #3750

Boasting a staggering weight of over 400,000 pounds and a length exceeding 80 feet, the SD90/43MAC is one of the world's most formidable and powerful single diesel locomotives, with an impressive 4,300 horsepower tractive effort. This locomotive has undergone three distinct production "versions" over time.

The SD90/43MAC was initially designed to be equipped with a 6,000-horsepower engine. However, it was ultimately fitted with a smaller, yet more reliable 4,300-horsepower engine, which became the standard configuration adopted by most railroads, even though the option to upgrade to the higher horsepower engine was available at a later date.

The SD90/43MAC's power is further enhanced by its Powerful five-pole KATO motor, which is complemented by dual brass flywheels. This combination ensures smooth and efficient operation, delivering exceptional performance.

Regarding the locomotive's features, it comes equipped with a Directional Headlight and preprinted numberboards, adding to its visual appeal and functionality. The Kato magnetic knuckle coupler provides secure and reliable coupling, while the DCC Friendly mechanism is ready for drop-in decoder installation, making it compatible with various DCC (Digital Command Control) systems, such as the Digitrax DN163K2 or Train Control Systems K2D4.

In summary, the SD90/43MAC is a true marvel of engineering, boasting impressive size, power, and technological advancements. Its versatility and compatibility with various DCC systems make it a highly sought-after locomotive among railway enthusiasts and operators alike.
