Metrolink officials say the train crossing at Doran Street in Glendale, just south of the 134 Freeway, is particularly dangerous because there's a propane company nearby.
There's also a heavy flow of tanker trucks and other vehicles across the tracks.
/* Metrolink*/ is planning $6 million in safety improvements, including better signals and new crossing gates.
It will also enlarge the intersection so vehicles don't line up on the tracks.
