Track signals were modified to let the train engineer know to reduce speeds at five curves and five bridges. The train will automatically stop if the engineer fails to slow down. Work required by the Federal Railroad Administration to update the signals in the wake of December's Bronx derailment finished last week with the completion of the Devon Bridge in Stratford, Conn. The MTA had until September to make the changes. @danrivoli Dan covers transportation, politics and general assignment news for amNewYork. He is a Staten Island native who lives in Brooklyn.
