I think you're a bit hasty in flipping the bozo bit, Glatt. I didn't see anything in that article that says that they've been able to reproduce the conditions that caused the accident. And I can tell you from experience that debugging can be hard. Especially so when you've got hardware and software involved. Not to mention that part of the circuit is train tracks that live outdoors.

Before pointing and laughing at these folks I'd want to know if they have access to all the circuitry and microcode involved. If they don't, they're trying to debug this thing blind. I'd also like to know if they've been allowed to try to reproduce this under working conditions. They may not. Metro may not want to risk squishing one or two of their trains to find the answer to this issue.
