WASHINGTON (AP) — The Latest on the National Transportation Safety Board's investigation on the causes of train crashes in Brooklyn and Hoboken (all times local): 11:30 a.m. Federal investigators are blaming a lack of required testing for sleep apnea for recent train accidents in New York and New Jersey that killed one person and injured more than 200. The National Transportation Safety Board released a report Tuesday on accidents at Hoboken in September 2016 and in Brooklyn in January 2017. In both crashes the train's engineers were found to have undiagnosed sleep apnea and couldn't remember their trains accelerating before the crashes.
