Using NTD data and coordinating the SSO for Rail Fixed Guideways annual reporting to provide more causal data, FTA formulated the Rail Transit Safety Action Plan by:

• Examining 10-year trends, using the Non-Major Summary Reporting Module (S&S 50) and the Major Safety and Security Incident Reporting Form (S&S 40) from 2002 to 2005 and SAMIS trend data from 1995 to 2001.
  
• Conducting an in-depth review of Form S&S 40 for the time period between January 1, 2003, and June 30, 2005; this includes 1,147 incidents, 137 fatalities, 903 injuries, and $8 million in property damage for the LR and HR modes.
