An incident at Copiague’s Long Island Rail Road station Wednesday afternoon caused a cascade of delays and three cancellations on the Babylon line.

“We had a train crew report a person running across the tracks and possibly struck by the train,” LIRR spokesman Aaron Donovan wrote in an email. “We inspected the train itself and realized that no person had been struck.”
