Launched by EMD in January 1972, the SD40-2 has earned its place as one of the most iconic diesel locomotives in history! With nearly 4,000 units produced between 1972 and 1989, this powerhouse delivers an impressive 3,000 horsepower and outshines many higher-horsepower models in reliability. The SD40-2 set the gold standard for the rail industry for decades!

Sharing a robust frame with the SD38-2 and SD45-2, the SD40-2 features an extended design to accommodate the innovative HT-C trucks, which are 1.5 feet longer than the Flexicoil trucks found on the SD40. This extension, along with similarly sized long hoods, gives the SD40-2 its signature "porches" at either end—perfect for spotting enthusiasts! You can easily identify it by its three roof-mounted radiator fans and a distinctive single large exhaust stack.

In 2025, we’re thrilled to model the original standard SD40-2, complete with eight stunning prototypical paint schemes and two exciting military fantasy schemes! Each model is powered by our state-of-the-art Paragon4 DC/DCC Sound & Control System. Plus, we’re offering a unique road number in each paint scheme in our Stealth Series—these models are no-sound and DCC-ready, perfect for those looking to customize their experience. Get ready to celebrate the legacy of the SD40-2!
