A New York City subway derailment earlier this month was caused by a flagger losing radio communication with a transit system supervisor, according to a preliminary report from the National Transportation Safety Board.
Two trains collided on Jan. 4 disrupting subway service to Manhattan’s Upper West Side. About 22 passengers and three crew members suffered minor injuries. The subways are operated by the Metropolitan Transportation Authority, the biggest public transportation provider in the US.
