Despite the age of these trucks, they saw more than seventy years of service in some applications. The arch bar was allowed in interchange service until about 1941. On railroads that were not common carriers such as logging or other industrial lines, this restriction of the trucks did not apply since the trucks did not operate on rails other than the owner's. The Northern Pacific, for example, used truss rod frame maintenance of way cars fitted with arch bar trucks well into the early 1970's. Many logging railroads also used them at least until then.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eScrews not included\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe term Code 110 and Code 88 relates to the width of the wheels and has no relationship to track code. Code 110 wheels are .110\" wide and Code 88 are .088\" wide. Code 110 wheels are the common (or \"Standard\") width wheels and Code 88 are what is called \"Semi-Scale\" and are used when the modeler wants a more prototypical looking wheel width. Actual HO-Scale prototypical wheel width would be around .067\" wide and although they will run OK on the average track they will not go through common turnouts and crossings. Code 88 (.088\") is just about the minimum width of wheel that will run on most standard or common track if gauged correctly. It really is a matter of appearances because there's very little operational differences between running Code 110 or Code 88 wheels. Code 88 wheels look really good and are most noticeable on open frame cars like hoppers and tank cars. However, they also look great on boxcars, gondolas, and reefers but not quite as noticeable. As mentioned above track code and wheel code have no relationship meaning Code 110 and Code 88 will run on most any code of track. Track code is simply the measured height of the rail, code 100 is .100\" tall, code 83 is .083\" tall, code 70 is .070\" tall, and so on.\u003c\/p\u003e","brand":"Kadee","offers":[{"title":"Default Title","offer_id":50060806193398,"sku":"KAD-501","price":10.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/0560\/files\/00501.jpg?v=1772391288","url":"https:\/\/mrmuffinstrains.com\/products\/kad-501","provider":"MrMuffin'sTrains","version":"1.0","type":"link"}
