Federal investigators were trying to determine whether the two-float parade had been given enough warning to clear the tracks.MIDLAND, Texas - Organizers of a parade in West Texas in which U.S. military veterans were killed when a train plowed into a truck had been using the same route for three years.
National Transportation Safety Board spokesman Mark Rosekind made that announcement Sunday.
Four war veterans were killed during the parade in Midland on Thursday.
