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 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 Code .110 33\" smooth back wheels Accurate markings Incredible detail, true to prototype Non-magnetic metal wheels Highly flexible sprung trucks Metal sideframes and fully sprung bolster Smooth-tracking, free-rolling, contoured insulated axles RP-25 free-rolling wheels\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eUse and assemble this product according to the manufacturer instructions and the package contents stated above.\u003c\/p\u003e\u003cp\u003eBrowse \u003ca href=\"\/es\/collections\/model-building-supplies\"\u003emodel-building supplies\u003c\/a\u003e.\u003c\/p\u003e","brand":"Kadee","offers":[{"title":"Default Title","offer_id":53053346152760,"sku":"KAD552","price":13.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0021\/6049\/2625\/files\/kad552.jpg?v=1790758450","url":"https:\/\/munclemikes.com\/es\/products\/kadee-552-asf-50-ton-trucks-with-33-wheels","provider":"Muncle Mikes","version":"1.0","type":"link"}
