writes with NBC's report that Washington, DC's Metrorail system has been completely shut down for at least 29 hours
, so crews can check 600 underground jumper cables:
A problem with those jumper cables caused a fire at the McPherson Square station early Monday and was also the cause of a fatal smoke incident in January, 2015, that killed one person and injured others. The safety checks could have been delayed until the weekend or conducted at night over about six days, officials said. But if the system were kept open, a public announcement about the risk would have to be made. That would have put passengers, and Metro, in the awkward position of publicly acknowledging that it was operating despite being aware of a potentially deadly safety problem. Metro also would have been liable in the case of any crashes or calamities. The shutdown prompted the Washington Post to publish an editorial titled It's official: Metro is a national embarrassment."
