"METRO has a severe learning disability"

https://www.washingtonpost.com/local/trafficandcommuting/ntsb-report-on-fatal-2015-metro-smoke-incident-is-said-to-criticize-metro-first-responders-and-others/2016/05/02/a414f3d2-107e-11e6-8967-7ac733c56f12_story.html 

And, WMATA is suing Parsons Brinkerhoff for negligence in failing to oversee design and construction of the Silver Spring Paul S. Sarbanes Transit Center (despite the fact that Montgomery County MD was the construction manager of record for the SSTC)! This is the same METRO that was paid a million dollars to review the plans and the construction; and, didn't discover that there are no expansion joints despite a METRO requirement that expansion joints be located no farther apart than every 100 feet! 

Good luck with your lawsuit, WMATA!
