| 摘要： | The Federal Railroad Administration (FRA) contracted with the Association of American Railroads (AAR), Transportation Test Center (TTC)-now known as the Transportation Technology Center-Pueblo, Colorado, to study in-revenue service loads on stub sill constructed tank cars. Over 162,000 of these cars have been placed into service 1950. The FRA has been investigating incidents of fatigue cracking at the attachment of the stub sill to the tank shell of these cars. As a result, the FRA has undertaken a program to work with industry representatives to further investigate the causes of the fatigue cracking and recommended preventive measures. |
