The Oxnard rail crossing that was the scene of Tuesday's Metrolink derailment is the 23rd most hazardous in California, according to data from the Federal Railroad Administration.
In 2014, two people were killed when their vehicle was struck by an Amtrak train at the Rice Avenue crossing.
According to data from the U.S. agency, the crossing had two collisions in 2010 and one in 2009.
The data indicate the Rice Avenue crossing had more collisions than any other Ventura County crossing in the 2009-2013 period.
The issue of rail crossing safety has been raised before.
In 2009, The Times performed a data analysis showing so-called grade-level street crossings used by Metrolink trains such as the Rice Avenue junction had a particularly high number of accidents or near-collisions.
Twelve locations accounted for about one in five crossing accidents, and of all accidents, nearly one in four were along a 17-mile corridor in the San Fernando Valley. The most dangerous intersection was Sunland Boulevard at San Fernando Road in Los Angeles, at which there were 13 incidents. Buena Vista Street in Burbank, with nine, had the second-worst record.
Officials have talked about making some of these crossings safer, in some cases with extra barriers. But building more grade separations has been a slow process because such projects are expensive.
