Donn’s blog about light rail is pretty good, but the most interesting part of the story is on the right hand side of the page of the link she posted, look at the multi-media section and click on the “metro train accidents” .
There is a running tally of how many they’ve had in the past year, plus a detail on each one. For the curious but lazy (no comments John), there have been 665 accidents since Oct. 2003 involving a collision that caused an injury or at least $1000 in damages.
