I remember hearing about that one. I think it happened maybe around 1996-97. I too never heard much about it in review, and would be interested in learning the details of how it happened. I remember the news coverage interviewing trainmen who walked out of the yard office and saw derailed freight cars careening toward them tearing up everything in their path. They demolished a large part of the yard office. I had the impression that they had quite a bit of warning that the runaway was coming.
