Two years ago Ryan Nelson and Gerry Nybo of Detroit Lakes died when a Burlington Northern Santa Fe Train hit their car at a railroad crossing. Nelson and Nybo were just two of the 402 people killed in similar accidents in the US in 1999. For the Nybo and Nelson families the accident has left many unanswered questions: questions they say the BNSF has shown little interest in answering. Now the dead mens' parents have organized Citizens Against Railroad Tragedies, a group working to force changes in the way such accidents are investigated. MainStreet Radios Bob Reha reports.
