More precise information of each train’s whereabouts would permit trains to travel closer together without compromising safety, and therefore allow more services to be run
Save time by listening to our audio articles as you multitaskRationing space this way can, though, lead to inefficiency. . But what might seem the obvious approach to doing this—to employ the satellite-based global positioning system or one of its equivalents—is not actually suitable.is unavailable in tunnels. And where several sets of tracks run in parallel satellite-based systems can have difficulty distinguishing which track a train is on, with potentially catastrophic consequences.
His invention, dubbed the Magnetic Railway Onboard Sensor and unveiled on September 20th at the InnoTrans trade fair in Berlin, uses information encoded in the very rails a train is running on, in the form of something called their magnetic permeability. Employing this, that train’s position on the network can be determined exactly.works by lowering a pair of detector coils over each rail and passing alternating currents through them.
To get the system working on a particular route, a test train rides it a few times to map out the fluctuations in the rails. After that, trains running the route would continually compare the permeability measurements from the detectors with those on the map, and then report their position to the network traffic controller.
Local changes in magnetic permeability caused by wear and tear or lightning strikes would show up during routine usage and, once confirmed, could be added to the map. Moreover, becausedetector-coils come in pairs, the different times that each pass the same pattern in the track can be used to calculate a train’s speed and acceleration more accurately than the alternative of measuring the rotation of its wheels, because metal wheels on metal rails frequently slip.
