HO SD40T-2 Locomotive with DCC and Sound SP Speed Letter #8237 (ATH73152)

This HO-scale SD40T-2 locomotive with DCC and sound reproduces Southern Pacific’s Speed Lettering era in a ready-to-run model. Based on the six-axle tunnel-motor design, it includes an onboard DCC decoder with Tsunami2 sound and can operate on both DC and DCC layouts, delivering authentic engine, horn, and bell sounds as you run it. The SP Speed Lettering details are captured with updates such as a revised nose, front ditch lights, and a relocated horn, giving the model a distinctive look on any layout.

Inside is a highly detailed injection-molded body with fine-scale handrails, photo-etched windshield wipers, separately applied air tanks, and see-through dynamic brake fans. It rides on nickel-plated, blackened machined wheels with RP25 contours and a smooth 5-pole motor with flywheels for quiet, reliable operation. Fully assembled and ready-to-run, it’s designed for HO layouts and is best run on a 22-inch minimum radius, with LED lighting and full function control to deliver lifelike operation and sound.
