S. F.(R) A-3 Ride Control(R) 50-ton freight truck was introduced in the 1940s and is one of the forerunners of modern freight trucks. Features embodied into this design include a longer spring travel, no spring planks and constant friction control using friction castings in the bolster to dampen excessive lateral roll of the car. These design features allowed for a higher train speed with less danger of derailment than previous designs. ASF(R) sold over 140,000 sets by 1949. This truck is excellent for modeling the transition era up to 1994 when friction bearings were no longer allowed in interchange service.\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: times new roman, times; font-size: medium;\"\u003e- Code .110 33\" smooth back wheels\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: times new roman, times; font-size: medium;\"\u003e- Accurate markings\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: times new roman, times; font-size: medium;\"\u003e- Incredible detail, true to prototype\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: times new roman, times; font-size: medium;\"\u003e- Non-magnetic metal wheels\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: times new roman, times; font-size: medium;\"\u003e- Highly flexible sprung trucks\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: times new roman, times; font-size: medium;\"\u003e- Metal sideframes and fully sprung bolster\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: times new roman, times; font-size: medium;\"\u003e- Smooth-tracking, free-rolling, contoured insulated axles\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: times new roman, times; font-size: medium;\"\u003e- RP-25 free-rolling wheels\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"PowerHobby","offers":[{"title":"Default Title","offer_id":50838136226088,"sku":"KAD552","price":8.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/7238\/6856\/files\/kad552.jpg?v=1778802440","url":"https:\/\/islandhobbynut.com\/products\/kadee-552-ho-50-ton-a-s-f-a-3-ride-control-self-centering-trucks-w-wheels","provider":"Island Hobby Nut","version":"1.0","type":"link"}
