"The Federal Railroad Administration (FRA) of the United States Department of Transportation is the Federal agency responsible for promoting the safety of the nation's passenger and freight railroads. FRA fulfills this responsibility by developing programs that identify, monitor, and address railroad safety issues, and by promulgating and enforcing regulations that prescribe minimum rail safety standards. On May 4, 1998, FRA published rail safety regulations for the preparation, adoption, and implementation of emergency preparedness plans by railroads connected with the operation of passenger trains, including railroads hosting the operations of rail passenger service. 63 Federal Register (FR) 24676. These regulations became effective on July 6, 1998, and are codified in Part 239 of Title 49 of the Code of Federal Regulations (CFR). This basic guide outlines what is required in an emergency preparedness plan ('plan') to assist railroads in developing their plans. However, this guide is not an all-encompassing document, and nothing in this guide changes the requirements in the regulations. Railroads have the responsibility for developing and implementing individual emergency preparedness plans that comply with the regulations based on the specific circumstances of each railroad's operations."
