Cheap radar-based obstacle detectors could cut the worldwide death toll at railway crossings, safety experts say. Their claim follows an accident in the UK on Saturday in which an express train ploughed into a stationary car on a level crossing (grade crossing) near Aldermaston in Berkshire, killing the car’s occupant and six people on the train. Network Rail, which is responsible for the British rail infrastructure, was already considering the use of obstacle detectors before the crash. A radar system that detects vehicles on the track could be used to apply the brakes and halt trains automatically, says John Davies,
