The Short Line Safety Institute (SLSI) is dedicated to the continuous improvement of safety and safety culture across all short line and regional railroads in the United States. Strengthening a railroad’s safety culture may result in less frequent or severe accidents and create a safer working environment. SLSI defines safety culture as the shared values, actions, and behaviors that demonstrate a commitment to safety over competing goals and demands, based on the U.S. Department of Transportation (DOT) Safety Council’s safety culture definition (Morrow & Coplen, 2017). SLSI is able to provides its services via a partnership with the Federal Railroad Administration’s (FRA) Office of Research, Development and Technology (RD&T).
