The N Scale Broadway Limited EMD SD40-2 is based on one of the most popular diesels ever built. Introduced by EMD in January 1972, the SD40-2 is one of the most popular diesel locomotives of all time. Between 1972 and 1989, EMD built nearly 4,000 units. These 3,000 horsepower machines were found to be more reliable than higher horsepower locomotives, and the SD40-2 became the standard of the industry for several decades. The SD40-2 shares a common frame with the SD38-2 and the SD45-2. The frame was lengthened to accommodate the new HT-C trucks, which were 1.5 feet longer than the Flexicoil truck found on the SD40's. With a longer frame, but similar sized long hoods, the SD40-2's have distinctive "porches" on either end. These empty areas are good spotting features for SD38-2 and SD40-2 locomotives. The SD40-2 can be further distinguished from the SD38-2 by its three roof-mounted radiator fans and a single large exhaust stack. This Stealth Series no-sound/DCC-ready model operates on DC out of the box, or a modeler can easily install their DCC decoder of choice. Out of the box, front and rear lights are directional, and other lights are always ON with track power. Additionally some lighting functions may be missing depending on selected aftermarket decoder the modeler installs. This model includes a motherboard with a NEXT18 18-pin decoder socket so you can add your favorite DCC or sound decoder when you're ready. It also features a built-in speaker so you won't have to add one later. Other features include a heavy die cast chassis and select roadname-specific details. Its wheels are profiled to operate on Code 55 and larger rail and curves of 9-3/4" radius but larger curves are recommended. The EMD SD40-2 is one of many Broadway Limited N Scale locomotives.
