This HO scale model features an all-new Paragon4 sound and control system, delivering synchronized puffing smoke that matches the chuff sound for an incredibly realistic experience. You can adjust the smoke intensity and timing to your preference, while the integral DCC decoder with Back EMF ensures industry-leading slow-speed performance in both DC and DCC modes. Built for power and precision, the locomotive boasts a rugged five-pole can motor with a skew-wound armature, paired with a heavy die-cast boiler, tender body, and chassis for maximum tractive effort. Every detail has been carefully crafted, from the premium paint scheme that matches the prototype to the prototypical lighting with independently controllable headlight, reverse light, cab light, and front marker lights. The model comes with factory-installed engineer and fireman figures, along with numerous separately applied details like handrails, grab irons, ladders, piping, cab glass, whistle, brass bell, and markers. Rubber traction tires enhance pulling power, and the locomotive operates smoothly on curves as tight as 18 inches. Authentic PRR B6sb sounds, including multiple whistle options, complete this highly detailed and powerful model.
