These compact cars are patterned after the prototypes that railroads used to calibrate the track scales where freight was weighed. Sent back to the shop for regular reweighing, a car like ST1 was a familiar sight moving across the system, which makes it an easy and prototypical addition to any operating scheme.\u003cbr\u003e\u003cbr\u003eItem 920-105303 carries a diecast body for plenty of weight and rolls on 33 scale inch RP-25 turned metal wheels fitted with Proto MAX metal knuckle couplers. Road-specific details include the correct side and top access doors, wheel bearings and hand brake, factory-applied wire grab irons, and photo-etched brass placards matched to the prototype. Park it on a yard siding or an industrial spur, carry it on a flatcar as a load, or pair it with the Cornerstone Track Scales kit (933-3199, sold separately) to add another operating chore to your railroad.\u003cbr\u003e\u003cbr\u003eKey Features:\u003cbr\u003e- HO scale (1:87) ready-to-run scale test car\u003cbr\u003e- Item 920-105303 from Walthers Proto\u003cbr\u003e- Road name and number: Chessie System\/Chesapeake \u0026amp; Ohio ST1\u003cbr\u003e- Diecast body for maximum weight\u003cbr\u003e- 33 scale inch RP-25 turned metal wheels\u003cbr\u003e- Proto MAX metal knuckle couplers\u003cbr\u003e- Factory-installed wire grab irons and photo-etched brass placards\u003cbr\u003e- Road-specific: staff hand brake, covered wheel bearings, as-built top cover, round side doors with release latch bar\u003cbr\u003e- Pairs with the Cornerstone Track Scales kit (933-3199, sold separately)","brand":"Walthers","offers":[{"title":"Default Title","offer_id":48169804955898,"sku":"920-105303","price":47.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/9371\/5706\/files\/920-105303.jpg?v=1787643540","url":"https:\/\/blackforesthobby.com\/products\/walthers-proto-920-105303-ho-scale-scale-test-car-chesapeake-ohio-st1","provider":"Black Forest® Hobby Supply Co","version":"1.0","type":"link"}
