Less than a month ago, Amtrak's top executive, Wick Moorman, said the company needed to improve safety on the rails. Along with safety training for supervisors, the rail agency has created a department focused on safety compliance for track workers, and plans to expand its scope, an Amtrak spokeswoman said. It and the Federal Railroad Administration are reviewing rules and procedures that can be improved. Since the crash, Amtrak has introduced a form that foremen must jointly fill out at shift changes to document safety tasks.
