HO SD45T-2 Locomotive DCC & Sound SP Speed Letter #9402 (ATH86974)

HO Scale SD45T-2 Locomotive with DCC and Sound in SP Speed Letter 9402. This six-axle diesel-electric tunnel-motor captures SP power from the 1970s in the Speed Letter scheme and is built for authentic HO-scale operation with DCC compatibility. It features a nose headlight, a modified L-window cab, roof A/C and bell, a Nathan P-3 horn on the long hood, walkways with ditch lights, a large front plow, and a large front anticlimber for an accurate silhouette.

Fine-scale details surround the shell, including handrails, photo-etched windshield wipers, separate air tanks, LED lighting, and fixed see-through cab windows, along with HTC truck sideframes and nickel-plated, blackened machined wheels with RP25 contours for reliable tracking. The drive uses all-wheel power with a 5-pole motor, flywheels, and a multi-link drivetrain for smooth, quiet operation. The model is DCC-ready via a 21-pin NEM Quick Plug, and sound-equipped versions include an onboard DCC decoder and SoundTraxx Economi sound, with engine, horn, and bell sounds operable in DC and full function control in DCC. Prototypical notes: the SD45T-2 is a six-axle tunnel-motor built in the early 1970s, powered by a 20-cylinder 645-series engine (3600 hp) and nicknamed Tunnel Motors for their cooling in tunnels. Minimum radius 18 inches, recommended 22 inches.
