A standout traffic marker that alerts people on foot or behind the wheel about a coming rail intersection and possible train movement. Built tough using rust-proof aluminum, these markers come coated with reflective material - either solid-grade or super-bright - to stay clear when it's dark or stormy. Common icons like the yellow circular RXR notice ahead or the white X-shaped crossbuck follow standard rules set by transport authorities, helping folks react fast no matter where they are.
They serve a key protective purpose by telling drivers to slow down, get ready to halt, keep eyes open for incoming locomotives, making passage safer at both signal-equipped and unmarked rail spots.
