In this photo taken June 28, 2011, a worker stops traffic as state transportation officials join investigators for the National Transportation Safety Board near Fallon, Nev., to conduct tests and examine new crossing guard equipment where a truck slammed into an Amtrak train on June 24. The crash killed the truck driver, a conductor and four others on the train. Investigators closed the highway in 30-minute intervals most of the day to check the equipment and measure distances for the safety investigation at the crossing. One of the Amtrak passenger cars that burned in the fiery crash is in the background. (AP Photo/Scott Sonner) less
