Some nice signs and railroad signals in the beginning of this 1950's Union Pacific Railroad safety video called "Look Listen Live."

"Last Clear Chance." MST3K made fun of this, but there still some unorthodox signs here.

BTW, I thought somebody covered this one already.

Reminds me of all those safety films that I endured during high school! Some of that looked like the 1930's and 40's.
