This two-unit A-B set pairs an F7A with an F3B, delivering authentic silhouette and ready-to-run power for freight or mixed-traffic operations on model railroads.\u003c\/p\u003e\n    \u003cp\u003eInside, the models pack advanced features for realistic running and sound. They include onboard DCC decoders with SoundTraxx Tsunami2 sound and dual cube speakers, with operation in both DC and DCC modes, and separate sound boards for each unit. Lighting and beacons illuminate prototypical operation, while a Genesis-style drivetrain with a 5-pole motor and heavy die-cast frame provide smooth, pulling power. Body-mounted scale knuckle couplers (Kadee-compatible), RP25 wheels, see-through cabs with full interiors, and etched metal detail parts enhance realism. A DCC-ready Quick Plug with a 21-pin NEM connector simplifies upgrades, and road-number-specific detailing includes 365 with cut skirts and 370 and 336-B with full skirts. Minimum operating radius is 18 inches, with 22 inches recommended for best performance.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Athearn (ATH)","offers":[{"title":"Default Title","offer_id":47924932673588,"sku":"ATHG19686","price":619.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0597\/6653\/8292\/files\/ATHG19686.jpg?v=1782145546","url":"https:\/\/nankinhobby.com\/products\/athg19686","provider":"Nankin Hobby","version":"1.0","type":"link"}
