Champaign, IL -- Broken rails or damaged wheels can cause train accidents with potential loss of life, injury or property damage. Researchers at the University of Illinois are fabricating fiber-optic sensors that can improve train safety by detecting flaws in rails and wheels. “Our sensors are based upon optical signal transmission through sensitive optical fibers that are firmly attached to the rails with epoxy and tape,” said Shun-Lien Chuang, a UI professor of electrical and computer engineering. “We use fiber optics to sense an environmental change – such as the weight of a passing train or the strain created by a cracked, broken or buckled rail.”
