Many occupational hazards exist for roadway workers on or about railroad tracks.  The environment can change rapidly on the railroad. Roadway workers must be focused to recognize those changes and adapt on-track protection as necessary.  The Roadway Worker Protection (RWP) regulation was implemented in 1997.  Even though there have been significant reductions in fatalities over the years, accidental deaths still occur, and recent incidents could have been avoided if situational awareness was improved and good communication practices were utilized.
