Ed- <br /> <br />According to my handy dandy GCOR flat spot measuring card (BNSF issues) Rule 101.28 provides that a car with a single flat spot of 2 1/2 inches or greater in length on one or more wheels must be set out at first available point and a car with two flat spots less than 11/2 inches apart that are each 2 inches or greater in length must be set out at the first available point. <br /> <br />LC <br /> <br />[quote]QUOTE: <i>Originally posted by edblysard</i> <br /><br />Ok, here we go. <br />AAR Field manual, 2003. <br />Rule 41, page 269 <br /> <br />Shelled tread: whenever any shell or spall is 1 inch in diameter, the wheel must be removed from service. <br />Islands of original tread surface metal contained in the shell or spall will not be considered as part of the area of the shell or spall. <br />(in other words, it has to be a complete 1 inch spall. ) <br /> <br />page 270 Built up tread. <br /> <br />A wheel is condemnable whenever the tread has built up metal 1/8th inch or higher than the wheel tread. <br /> <br />page 277 deals with impact detectors and out of round wheels. <br />Impact in excess of 90,000 pounds for a single wheel is a defect. <br />(there is about three more paragraphs) <br /> <br />Slid flat, page 279 <br /> <br />Slid flat: <br />A; 2 inches or over in length <br />B: 2 or more adjoining spots each 1 1/2 inch or over in length. <br />C: Mate wheel is automatically condemable regardless of of length of flat spot. <br />D: apply guage as shown...(drawing of how to measure ) <br /> <br />Help any? <br /> <br />Ed <br />[/quote]
