A national safety board says only twelve states -- including Arkansas -- have made satisfactory progress to improve safety at ungated railroad crossings. The National Transportation Safety Board made recommendations to states after three children were killed by a train in 2000. The states that made progress include Arkansas, Connecticut, Florida, Hawaii, Idaho, Indiana, Kentucky, Montana, Nevada, New Mexico, South Carolina and Texas. And seven of the 10 states with the most collisions between trains and all kinds of vehicles at grade crossings have largely ignored the recommendation. They are Alabama, California, Georgia, Illinois, Louisiana, Mississippi and Ohio.
