- W752685145 abstract "Railroads are pushing ahead with implementation of positive train control (PTC), in response to a number of influences. The Federal Railroad Administration (FRA) has issued a mandate that all shared-use lines, as well as those handling hazardous materials, must be equipped with PTC by 2015. Additionally, the industry now sees PTC as a tool for helping to fill the capacity gap with minimal capital investment. Thirdly, with President Obama's endorsement of high-speed rail, the prospect of conventional trains traveling at speeds on the order of 100-110 mph is more likely and will require some kind of PTC. The major railroads are using different systems, with a rulemaking due out soon in 2009 to set the requirements for core PTC. A key component is the 220-MHz licensed radio frequency over which all PTC train/wayside communications will take place, devised as part of an interoperability agreement, which is allowing the industry to come together with interoperable systems. For the affected track to meet the FRA mandate, some 75,000 wayside devices will have to be upgraded, at a rate of seven to 10 per day. Locomotives will have to be upgraded at a rate of two to three per day. Another aspect of PTC is the potential uses to which the wireless network can be put for other operational objectives, including tracking cargo, timing trips, and the like." @default.
