- W756745974 abstract "The first test using satellite-based global-positioning technology in a positive-train-control (PTC) installation on a stretch of Union Pacific track north of Bloomington, Illinois is a significant step toward deploying more high-speed trains on the U.S. rail network. PTC is one way to comply with rules issued by the Federal Railroad Administration that mandate automatic speed enforcement for trains traveling faster than 79 mph. The old way was expensive to maintain and outmoded. With public support, Lockheed-Martin has developed the system which was installed on the Union Pacific track section. This sits in the federally designated Chicago-St. Louis high-speed rail corridor. The system queries crossings to make sure the gates are operating properly and presents the engineer with a video screen that shows operating authority track warrants and instructions from the dispatcher, block authority, how far ahead the train is permitted to travel at its present speed, and a track diagram showing the train's location in the track network and in relation to other trains. By next fall, all Amtrak and Union Pacific locomotives in the test area should be equipped with the satellite system and the video screens, permitting full speed travel on the track." @default.
