The Federal Railroad Administration (FRA) is the federal agency primarily responsible for safety in the rail industry. FRA's safety programs were last authorised in 1994; their authorisation expired in 1998. Most measures of rail safety have improved significantly since FRA's last authorisation, including the number of grade crossing collisions and fatalities and the number of employee injuries and deaths. However, the improvements in safety measures have levelled off in recent years. Given significant projected continued increases in freight and passenger rail activity in the coming decade, there is concern that without additional efforts, some of the gain of the past decade may be lost. This book explores the issues, regulations and safety of U.S. railroads.
