The Association of American Railroads obtained samples of 121 lb/yd (UIC 60 Section 60 Kg/m) from three German rail mills as part of its ongoing investigation of domestic and foreign rail. These rails were of particular interest in view of the unconventional practice of bottom pouring ingots topped with insulating side boards. In addition, the rails are not control cooled. This practice is justified by the German steel makers in that they preheat all scrap and ingot molds and use a hot ladle which has been previously used for pouring steel of another heat.
