Abstract:

This report documents the findings and recommendations from an investigation into stop signal violations at several passenger railroads. The study collected data on accidents related to stop signal overruns (SSO) from the National Transportation Safety Board (NTSB) reports and from the Federal Railroad Administration’s (FRA) accident database to identify the common factors and provide a descriptive summary of the frequency and severity with which these events take place. Stop signal overrun data for six passenger railroads was collected and analyzed to identify their frequency over time. Qualitative data in the form of documents describing stop signal overruns and interviews with employees were conducted to identify how the railroad system produces stop signal overruns. The study identified a wide variety of factors that contributed to stop signal overruns and offered recommendations for mitigating these events.
