bws48, thanks for the link to the preliminary report. It is fascinating. The part about the doors that could not be opened in an emergency is very disturbing. As is the failure of coms. An article in WaPo indicates that emergency coms in the tunnels has been a longstanding issue. t sounds like the fire department responders did indeed switch to simplex mode on their radios, as I surmised up thread.

Hopefully the impending lawsuits will force some significant changes at metro.
