Of the more than 200,000 railroad crossings in the U.S., 15 have been the site of ten or more incidents during the last decade, according to a list released by the U.S. Department of Transportation’s Federal Railroad Administration (FRA). (See list below). While fatalities have not occurred at all 15 crossings, repeated incidents increase the potential for injuries and loss of life. Surprisingly, the top three crossings are in one state: Arizona.

The identification of the high-danger crossings is part of the FRA’s effort to improve railroad crossing safety across the nation, and comes on the heels of FRA Administrator Sarah E. Feinberg’s recent letter to state DOT secretaries in which she provided a detailed round up of federal financial resources and FRA expertise available to help states reduce accidents at the crossings.
