LAKE OSWEGO, Oregon—Rail car manufacturer Greenbrier is going to design a new- -generation “Tank Car of the Future” for rail transport of hazardous freight, including flammable crude oil and ethanol, that can better withstand the additional demands associated with operating unit trains.
The new design will respond to safety criticisms of the existing legacy fleet of older DOT-111 tank cars, in the wake of the Lac-Megantic and other recent tank car incidents. The new car design is intended to meet anticipated new industry and government standards for tank cars transporting certain hazardous material. Greenbrier is also introducing retrofits for tank cars already in service or now being produced, significantly enhancing the safety of existing cars.
“Statistics from the Association of American Railroads (AAR) show that 99.9977 percent of all rail-carried hazardous material arrives at its destination without incident. However, recent high-profile derailments have clearly demonstrated the need for updating the North American tank car fleet to the highest practical safety standards,” said Greenbrier chairman and CEO William Furman. “Greenbrier is addressing the tank car 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 tank cars, as may be appropriate. This allows the industry to take immediate steps to improve public safety. It also preserves the massive investment in tank cars 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.”
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 tank cars in service in North America of which 255,000 were of the older legacy design. Among those tank cars, 170,000 were in hazardous transport, with 68,000 tank cars in crude oil and ethanol service.
Greenbrier will also provide retrofit offerings for newer tank cars 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 U.S. 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.
In North America, Greenbrier can build tank cars at a rate of 4,000 cars per year, and is increasing its capacity in light of higher demand for tank cars related to the energy renaissance in America. As of November 30, 2013, 47 percent% of Greenbrier’s backlog consisted of tank cars 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.
