  A railroad investigator talks on the phone at the scene of an accident where four veterans were killed and 16 other people were injured when a train slammed into a parade float carrying the returning heroes to a banquet last Thursday in Midland, Texas on Saturday, Nov. 17, 2012. Federal investigators were trying to determine whether the two-float parade had been given enough warning to clear the tracks. (AP Photo/Juan Carlos Llorca)
