New York City transit officials say the massive theft of copper cable along subway train tracks has caused major disruptions in service for hundreds of thousands of commuters. The Metropolitan Transportation Authority says the crime disrupted service along the entire length of the A and C lines on Wednesday morning. At least 500 feet of cable was discovered stolen from roughly 12 locations along the A train tracks near Howard Beach, Queens. It halted A train service between the Rockaway Boulevard and Broad Channel stations in Queens.
