The Greenbrier Companies announced February 5 that it will design a new generation of tankcars for rail transport of hazardous freight, including flammable crude oil and ethanol, that can better withstand the additional demands associated with operating unit trains. Greenbrier also is introducing retrofits for tankcars already in service or now being produced, significantly enhancing the safety of existing cars
The new "Tank Car of the Future" design will respond to safety criticisms of the existing legacy fleet of older DOT-111 tankcars, according to Greenbrier officials. The new car design is intended to meet anticipated new industry and government standards for tankcars transporting certain hazardous materials.
"Statistics from the Association of American Railroads (AAR) show that 99.9977% of all rail-carried hazardous material arrives at its destination without incident,” said Greenbrier Chairman and CEO William Furman. “However, recent high-profile derailments have clearly demonstrated the need for updating the North American tankcar fleet to the highest practical safety standards. Greenbrier is addressing the tankcar safety issue on two fronts--by supporting a 'Tank Car of the Future' and through offering retrofit alternatives for the legacy fleet, including our most recently built CPC-1232 tankcars, as may be appropriate. This allows the industry to take immediate steps to improve public safety. It also preserves the massive investment in tankcars now in service, by extending the time these cars could be used in hazardous material transportation as they ultimately transition over time to less hazardous service. The Department of Transportation (DOT) has yet to rule on industry recommendations to adopt the newer and safer CPC-1232 standards submitted to them in March 2011. These were subsequently mandated by the AAR on tankcars ordered after October 2011. When Greenbrier builds railcars, our top priorities are to ensure our workers' and the public's safety while protecting the natural environment."
In order to respond to immediate safety concerns, and in anticipation of future action by the DOT, Greenbrier is also introducing retrofits for legacy DOT-111 cars and newer cars that meet the current CPC-1232 standard mandated by AAR. As of November 2013, there were 272,100 DOT-111 tankcars in service in North America of which 255,000 were of the older legacy design. Among those tankcars, 170,000 were in hazardous transport, with 68,000 tankcars in crude oil and ethanol service.
Retrofit options for the legacy DOT-111 tankcars will include high-flow pressure relief valves, head shields, top fittings protection, and thermal protection. It is expected that appropriate retrofit choices could allow extended service for DOT-111 tank cars as these cars are placed in lower risk service over time. Industry research has shown that bottom and top appurtenances on the legacy DOT-111 tankcars are impacted in high speed derailments. Greenbrier's proposed retrofit is targeted to improve these tank car features, and adds head shields, to achieve better performance in a derailment event.
Greenbrier will provide retrofit offerings for newer tankcars built under the AAR's CPC-1232 standards, which applies to all tank cars ordered after October 2011. Greenbrier's retrofit package for newer CPC-1232 cars includes high-flow pressure relief valves and improved bottom outlet valve handles for any CPC-1232 cars in crude and ethanol service which were not originally equipped with these features.
Combined, these retrofits can meaningfully improve the safety performance of both car types in continued service. Greenbrier expects its "Tank Car of the Future" and retrofit offerings will comply with anticipated Class I rail carrier requirements as well as pending regulatory actions by the US and Canadian governments. The company's retrofitting work, as part of its Wheels, Refurbishment & Parts segment, will not materially impact production rates for new builds as part of its manufacturing segment.
Furman continued, "Greenbrier has a rich history of designing and building the world's most durable tankcars for delivering sensitive materials. For over 30 years, our Wagony Swidnica facility in Poland has built all types of pressure tank and specialty cars for the Western European rail system. European tankcar service is highly regulated, and typically consists of shorter, faster trains than in the United States and North America, with many advanced safety features and an excellent safety record for hazardous materials service.
"We are prepared to respond in part as the result of an order to build 500 pressure cars in North America. Currently, pressure cars are used to transport hazardous freight other than crude oil and ethanol. These cars exceed current tankcar standards for cars transporting crude oil and ethanol, as well as all new tankcar standards recently considered by AAR. Our pressure car experience will aid our design effort on the Tank Car of the Future for non-pressurized hazardous service, including the transportation of crude oil and ethanol.”
In North America, Greenbrier can build tankcars at a rate of 4,000 per year, and is increasing its capacity in light of higher demand for tankcars related to the energy renaissance in America. As of November 30, 2013, 47% of Greenbrier's backlog consisted of tankcars which are almost entirely the more advanced and safer CPC-1232 tank cars and pressure cars. Greenbrier no longer produces the legacy DOT-111 tank car for use in flammable service.
Greenbrier will collaborate with industry leaders to achieve a shared goal of providing the safest means of transportation of crude oil and ethanol by rail. Railroads already have addressed operating practices to improve safety, while energy and chemical shippers are evaluating the content of their commodities to verify proper packaging to protect the public and the environment, according to Greenbrier officials.
