This faithful HO model recreates the SDP45 prototype that replaced older E-units for passenger service in the 1960s, and it’s offered in Athearn’s Legendary Liveries as an exclusive, historically inspired paint scheme. The Demonstrator edition provides a distinctive roster piece that’s ready to run on a standard HO layout right out of the box.\u003c\/p\u003e\n\t\u003cp\u003eBuilt for reliable, smooth operation, the model features a Genesis driveline with a 5-pole motor, precision-machined flywheels, a multi-link drivetrain, and a heavy die-cast frame for traction and durability. It’s DCC-ready with Quick Plug and a 21-pin NEM connector for easy digital control, and body-mounted scale knuckle couplers provide realistic coupling. Road-number-specific variants cover a broad range of schemes—SP, BN, GN, UP, SP Daylight, HLCX, NYC, and more—while RP25-contoured wheels ensure smooth operation on standard HO track. The minimum radius is 18 inches (22 inches recommended), and Tsunami2 sound-equipped versions add authentic engine, horn, and bell sounds for a complete model railroad experience.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Athearn Genesis (ATHG)","offers":[{"title":"Default Title","offer_id":47609167609908,"sku":"ATHG-2009","price":208.69,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0597\/6653\/8292\/files\/ATHG-2009.jpg?v=1774293352","url":"https:\/\/nankinhobby.com\/products\/athg-2009","provider":"Nankin Hobby","version":"1.0","type":"link"}
