A recent report from the Associated Press has revealed some worrisome data regarding one of the nation’s most common types of rail tankers. An increase in the demand for ethanol, which is a highly-flammable fuel, has led to more tankers being put into service and an accompanying increase in the number of accidents. Many of these accidents also result in the release of dangerous chemicals, explosions, and even fires. According to AP, transportation officials were aware of the issues with the tanker’s design for the past two decades but declined to take it out of use.
The rail car, the so-called DOT-111, has been in heavy use on railroads around the U.S. for many years. The National Transportation Safety Board has brought to light several troubling factors in these accidents, which were reported as early as 1991 when the board released a safety study noting the problems. The tankers were found to be especially prone to puncture or tearing due to a thin steel shell, and the couplers at the ends can also tear off and potentially fly up when separated from between the cars. The AP, after analyzing over twenty years’ worth of data outlining federal rail accidents, found that the number of tankers breached increased from two between the years of 1990 and 2000 to 40 in the years since 2000.
