{"product_id":"athg-1717","title":"HO F3A\/F3B Locomotive Set with DCC and Sound FEC #503 #552 (ATHG-1717)","description":"\u003cdiv class=\"product_description\"\u003e\n\t\u003cp\u003eHO F3A\/F3B Locomotive Set with DCC and Sound, Freight FEC #503 and #552, is an HO-scale two-unit pairing that recreates GM EMD’s classic F‑unit diesel locomotives used on North American freight trains. The A and B units come with onboard DCC decoders and SoundTraxx Tsunami2 sound, plus dual cube speakers, delivering authentic engine, horn, and bell sounds on both DC and DCC layouts. Built for real-world operation, the models ride on a heavy die-cast frame with all-wheel drive, feature see-through cab windows and a full cab interior, and use directional LEDs to keep the locomotive looking convincing as it moves. Wiring is simplified by Quick Plug plug-and-play technology and a 21-pin NEM connector for easy setup.\u003c\/p\u003e\n\t\u003cp\u003eDetailing mirrors the prototype with etched metal fan grilles, separately applied detail parts, a detailed fuel tank, and body-mounted scale knuckle couplers compatible with Kadee. The A and B units house individual sound boards, so each unit can produce engine, horn, and bell sounds, with sounds active in DC and NMRA-compliant in DCC; some functions are limited in DC. The set is designed for HO layouts with an 18\" minimum radius (22\" recommended) and features RP25 wheels for smooth operation, a robust five-pole drive for traction, and a heavy frame for stability. It’s primed for weathering and grime to create a lived-in appearance, and road-name variations like FEC, ATSF, LN, MKT, SNCT, and CRIP reflect prototypical detail.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Athearn Genesis (ATHG)","offers":[{"title":"Default Title","offer_id":47608415256628,"sku":"ATHG-1717","price":539.13,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0597\/6653\/8292\/files\/ATHG-1717.jpg?v=1774291113","url":"https:\/\/nankinhobby.com\/products\/athg-1717","provider":"Nankin Hobby","version":"1.0","type":"link"}
