{"product_id":"ath28673","title":"HO RTR RS-3 Locomotive New Haven Railroad #539 (ATH28673)","description":"\u003cdiv class=\"product_description\"\u003e\n\t\u003cp\u003eHO-scale RS-3 Locomotive in New Haven livery, No. 539, is a ready-to-run model that brings the diesel era to life on an HO layout. The model features a finely detailed injection-molded body, metal grab irons, and fine-scale handrails, along with see-through etched radiator fan and cab windows. It rides on RP25-contoured wheels with all-wheel drive and electrical pickup for smooth, quiet operation, and it uses McHenry scale knuckle couplers for reliable coupling with freight and passenger cars. LED lighting provides long-life illumination, and the Quick Plug 21-pin interface makes DCC installation straightforward. The NH artwork is painted and printed to a faithful standard, and the model is fully assembled and ready to run, designed to fit typical HO track radii, including an 18-inch minimum radius.\u003c\/p\u003e\n\t\u003cp\u003ePrototype background and evolution: ALCO's RS-3 followed the RS-2, delivering about 1,600 horsepower from a 12-cylinder 244 prime mover, becoming a versatile mainstay on many roads. New Haven ordered RS-3s in multiple lots during the 1940s and 1950s, and the fleet eventually passed to Penn Central, Conrail, Amtrak and others; only one NH RS-3 remains today, No. 529, undergoing restoration. This model incorporates modern refinements: a redesigned, more powerful can motor for stronger, quieter operation; DCC-ready 21-pin plug, and, in sound-equipped versions, Tsunami2 sound with a cube speaker. LED lighting remains standard, and the DCC implementation is NMRA-compatible, with some DC functions limited. In addition to the performance upgrades, the model preserves the RS-3’s distinctive look—forward and reverse Blatt horns, a steam generator stack, nose vent and water tank, a single headlight, and NH decoration—so it sits convincingly on any layout depicting mid-century railroading.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Athearn (ATH)","offers":[{"title":"Default Title","offer_id":47906406400052,"sku":"ATH28673","price":159.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0597\/6653\/8292\/files\/ATH28673.jpg?v=1781651708","url":"https:\/\/nankinhobby.com\/products\/ath28673","provider":"Nankin Hobby","version":"1.0","type":"link"}
