In January 2010, the Federal Railroad Administration (FRA) issued a ruling on the implementation of Positive Train Control (PTC), with a timeline for adoption of the technology by the US rail industry. Following this ruling, several cost-benefit analyses were conducted, including one by L.E. Peabody & Associates, on behalf of the Chlorine Institute. These analyses ascribed large-scale commercial benefits to PTC implementation, including improved car velocity for shippers.
The Association of American Railroads (AAR) President and CEO Edward R. Hamberger has stated “This is the single largest regulatory cost ever imposed on our industry by the FRA, and as such, we take the mandate very seriously.” Due to the critical nature of this technology adoption, the AAR asked Oliver Wyman to respond to these analyses, and deliver an independent evaluation of potential commercial benefits to be derived from PTC. Mr. Hamberger has cited “There are many broad and general assertions out there on business benefits from PTC, so it was important to get an independent analysis and clear up any misconceptions that might exist. Oliver Wyman brings considerable expertise on these issues, both in the U.S. and Europe.”
After analyzing currently available information on PTC and current advancements in the use of technology by the rail industry, including public and private research and data, interviews with industry experts and railroad representatives, and case study information from railroads in North America and Europe, Oliver Wyman has outlined results in 4 categories, with the following conclusions:
1. Core Assumptions: Oliver Wyman has found no direct relationship between the use of precision dispatching and the implementation of PTC (precision rail dispatching is computer aided and uses a range of sophisticated techniques to ensure optimum train performance, in terms of network velocity and capacity usage). At the same time, Oliver Wyman has concluded that the adoption of PTC as currently planned by the Class I railroads (independent of precision dispatching) will not materially increase effective line capacity or train speeds, whether on single or multi-track mainlines.
2. Incremental Benefits Analysis: Many of the incremental benefits being claimed for PTC are based on the adoption of technologies that are not tied to PTC (such a precision dispatching) and as such should not be ascribed to PTC. Other benefits from PTC would only be realized from the adoption of an “advanced” PTC system, whereas the Class I railroads only plan to implement an “overlay” PTC system to meet FRA mandates. Additionally, Oliver Wyman has outlined the business risks from PTC implementation.
3. Shipper Benefits Analysis: Oliver Wyman has concluded that the net benefit to shippers from the planned implementation of PTC will be zero. Improvements in railroad on-time performance, and subsequent shipper benefits, would be attributable to precision dispatching, which is currently not in production use, is being developed independently from the PTC initiative, is not part of the FRA mandated PTC implementation, and is likely to be only marginally influenced by the roll-out of PTC.
4. European Experience with ERTMS: ERTMS is designed to overcome interoperability problems between the countries in the EU, due to different control and signaling systems in each country. While the ERTMS system includes safety components similar to those required by US PTC regulations, the primary goal of ERTMS is to make cross-border travel and trade more seamless, rather than to enhance safety or capacity. The key lesson to be learned from the ERTMS experience is that the versions of ERTMS that are most similar to PTC systems being implemented by the US Class I railroads are at best neutral with respect to capacity, and in many cases are showing an adverse impact on capacity. Additionally, the amount of European trackage covered by ERTMS is modest and the system will be implemented much more slowly than in the US, while the costs for implementing ERTMS have been much higher than the costs projected for US PTC system implementation.
