{"product_id":"mth22221482","title":"O Scale Premier RS-3 - Phase 3 Diesel Engine w\/Proto-Sound 3.0 (Scale Wheels)","description":"\u003cdiv\u003e\n\u003cp\u003eThere are diesel locomotives, and then there are legends. The American Locomotive Company (Alco) RS-3 belongs firmly in the latter category. Now, MTH Electric Trains is proud to bring this workhorse of the high iron to your O Scale layout with a level of detail and sound fidelity that must be heard to be believed.\u003c\/p\u003e\n\u003cp\u003eIntroduced in 1950 as an improvement on the RS-2, the RS-3 quickly became the definitive \"Road Switcher\" of its era. While EMD was capturing the market with the GP7, Alco carved out its own loyal following with the RS-3. Powered by the throaty 12-cylinder, 1,600-horsepower Model 244 prime mover, these units were famous for their versatility.\u003c\/p\u003e\n\u003cp\u003eThey looked just as natural hauling coal drags through the Appalachians as they did sprinting with commuter coaches outside of New York City or Chicago. Over 1,400 units were produced, and their signature smoking exhausts and distinctively rhythmic engine sounds endeared them to railfans for decades.\u003c\/p\u003e\n\u003cp\u003eOur latest O Scale recreation captures the soul of this Alco legend. Under the hood lies the Proto-Sound 3.0 onboard electronics system, bringing the RS-3 to life on your layout.\u003c\/p\u003e\n\u003cp\u003eListen to the authentic startup sequence, the labored chug of the Alco 244 prime mover under load, and the squeal of brakes as you spot cars at the industry siding and it wouldn't be an Alco without the smoke! Our fan-driven smoke unit features variable output, puffing in sync with the engine RPMs for the ultimate realism. Whether you run conventional AC or the MTH Digital Command System (DCS), you have precision control over every movement.\u003c\/p\u003e\n\u003cp\u003eWe understand that every modeler has a different standard for their right-of-way. That is why this run of Alco RS-3s is available in two distinct configurations:\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHi-Rail Wheels:\u003c\/strong\u003e Perfect for traditional O Gauge 3-rail operators. These models feature oversized flanges and piloting designed to navigate tighter O-31 curves and tubular track switches with ease. \u003cbr\u003e\u003cstrong\u003eScale Wheels:\u003c\/strong\u003e Designed for the 2-rail scale modeler or the 3-rail enthusiast who demands absolute fidelity. These models feature fixed pilots (no swinging gaps) and proper scale wheel flanges for operation on 2-rail code 148 or code 125 track (convertible to 3-rail fixed pilot operation).\u003c\/p\u003e\n\u003cp\u003eDon’t miss your chance to add this diesel icon to your roster. Whether switching the yard or leading a local passenger run, the Alco RS-3 with Proto-Sound 3.0 is ready for duty.\u003c\/p\u003e\n\u003c\/div\u003e\n      \n          \n        \n        \u003cdiv x-cloak\u003eFeatures\u003cul\u003e\n\u003cli\u003eIntricately Detailed, Durable ABS Body\u003c\/li\u003e\n\u003cli\u003eDie-Cast Truck Sides, Pilots and Fuel Tank\u003c\/li\u003e\n\u003cli\u003eMetal Chassis\u003c\/li\u003e\n\u003cli\u003eMetal Handrails and Horn\u003c\/li\u003e\n\u003cli\u003eMoveable Roof Fans\u003c\/li\u003e\n\u003cli\u003eMetal Body Side Grilles\u003c\/li\u003e\n\u003cli\u003eDetachable Snow Plow\u003c\/li\u003e\n\u003cli\u003e(2) Handpainted Engineer Cab Figures\u003c\/li\u003e\n\u003cli\u003eAuthentic Paint Scheme\u003c\/li\u003e\n\u003cli\u003eMetal Wheels, Axles and Gears\u003c\/li\u003e\n\u003cli\u003eO Scale Kadee-Compatible Coupler Mounting Pads\u003c\/li\u003e\n\u003cli\u003ePrototypical Rule 17 Lighting\u003c\/li\u003e\n\u003cli\u003eDirectionally Controlled Constant Voltage LED Headlights\u003c\/li\u003e\n\u003cli\u003eLighted LED Cab Interior Light\u003c\/li\u003e\n\u003cli\u003eIlluminated LED Number Boards\u003c\/li\u003e\n\u003cli\u003e(2) Precision Flywheel-Equipped Motors\u003c\/li\u003e\n\u003cli\u003eOperating ProtoSmoke Diesel Exhaust\u003c\/li\u003e\n\u003cli\u003eOnboard DCC\/DCS Decoder\u003c\/li\u003e\n\u003cli\u003eLocomotive Speed Control In Scale MPH Increments\u003c\/li\u003e\n\u003cli\u003eProto-Scale 3-2 3-Rail\/2-Rail Conversion Capable\u003c\/li\u003e\n\u003cli\u003e1:48 Scale Proportions\u003c\/li\u003e\n\u003cli\u003eProto-Sound 3.0 With The Digital Command System Featuring Quillable Horn With Freight Yard Proto-Effects\u003c\/li\u003e\n\u003cli\u003eUnit Measures: 18 1\/2” x 2 5\/8” x 4”\u003c\/li\u003e\n\u003cli\u003eOperates On 42\" Radius Curves Diesel DCC Features\u003c\/li\u003e\n\u003cli\u003eF0 Head\/Tail light\u003c\/li\u003e\n\u003cli\u003eF1 Bell\u003c\/li\u003e\n\u003cli\u003eF2 Horn\u003c\/li\u003e\n\u003cli\u003eF3 Start-up\/Shut-down\u003c\/li\u003e\n\u003cli\u003eF4 PFA\u003c\/li\u003e\n\u003cli\u003eF5 Lights (except head\/tail)\u003c\/li\u003e\n\u003cli\u003eF6 Master Volume\u003c\/li\u003e\n\u003cli\u003eF7 Front Coupler\u003c\/li\u003e\n\u003cli\u003eF8 Rear Coupler\u003c\/li\u003e\n\u003cli\u003eF9 Forward Signal\u003c\/li\u003e\n\u003cli\u003eF10 Reverse Signal\u003c\/li\u003e\n\u003cli\u003eF11 Grade Crossing\u003c\/li\u003e\n\u003cli\u003eF12 Smoke On\/Off\u003c\/li\u003e\n\u003cli\u003eF13 Smoke Volume\u003c\/li\u003e\n\u003cli\u003eF14 Idle Sequence 3\u003c\/li\u003e\n\u003cli\u003eF15 Idle Sequence 2\u003c\/li\u003e\n\u003cli\u003eF16 Idle Sequence 1\u003c\/li\u003e\n\u003cli\u003eF17 Extended Start-up\u003c\/li\u003e\n\u003cli\u003eF18 Extended Shut-down\u003c\/li\u003e\n\u003cli\u003eF19 Rev Up\u003c\/li\u003e\n\u003cli\u003eF20 Rev Down\u003c\/li\u003e\n\u003cli\u003eF21 One Shot Doppler\u003c\/li\u003e\n\u003cli\u003eF22 Coupler Slack\u003c\/li\u003e\n\u003cli\u003eF23 Coupler Close\u003c\/li\u003e\n\u003cli\u003eF24 Single Horn Blast\u003c\/li\u003e\n\u003cli\u003eF25 Engine Sounds\u003c\/li\u003e\n\u003cli\u003eF26 Brake Sounds\u003c\/li\u003e\n\u003cli\u003eF27 Cab Chatter\u003c\/li\u003e\n\u003cli\u003eF28 Feature Reset\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eEstimated delivery: DEC 2026\u003c\/p\u003e\n\u003c\/div\u003e","brand":"MTH","offers":[{"title":"Default Title","offer_id":51788261064937,"sku":"22221482","price":699.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/4797\/2329\/files\/22-22148-2.jpg?v=1788358848","url":"https:\/\/blackdiamondexpressmodeltrains.com\/products\/mth22221482","provider":"Black Diamond Express Model Train Station","version":"1.0","type":"link"}
