A bit of history of OL.
We started in 1972 when the average number of collisions at U.S. highway-rail grade crossings had risen above 12,000 incidents yearly. To address this tragic reality, the Idaho governor's office, along with the Idaho Peace Officers and
Union Pacific Railroad launched a six-week public awareness educational campaign called Operation Lifesaver to promote highway-rail grade crossing safety. After Idaho's crossing-related fatalities decreased that year by 43%, the successful program was adopted by Nebraska (1973) and in Kansas and Georgia the following year. Within a decade it had spread across the country. In 1986 a non-profit Operation Lifesaver national office was created to help support the efforts of state OL programs and raise national awareness on highway-rail grade crossing issues.

Although double track crossings are relatively rare in Texas, they do exist in Houston and I crossed one every day for several years to get to work. Here the risk was “one train can hide another”, a literal translation of a sign on many French ungated rural crossings on the Midi Main Line “un train peut en cacher un autre”.
