Jan 1, 2011 · This paper analyzes several critical parameters for predicting train derailment risk by using derailment statistics from the FRA accident database and related literature. A general method was developed to assess derailment risk by accident cause and FRA track class.

This study developed an accident cause–specific derailment risk model that simultaneously accounts for the interactions among dif-ferent accident causes that may be differently affected by track class upgrade. The paper is structured as follows: a general framework for derailment risk analysis is introduced, followed by analyses and mod-

This research develops a log-linear statistical model that can estimate the number of freight-train derailments ac-counting for railroad, accident cause, season, and traffic volume. The analysis shows that broken rails and track geometry defects are the two leading freight-train derailment causes on four major U.S. freight railroads.
Dec 1, 2011 · The research also shows that freight train derailment severity has been affected mainly by (1) train speed, (2) cause of the accident, and (3) train weight-to-train length ratio.
Derailments accounted for 72% of freight-train accidents in the United States from 2001 to 2010 (Liu et al., 2012). Corre-spondingly, the analysis and prevention of train derailments is a high priority in the rail industry and government.
