 The heat has been messing things up on Metro. Yesterday it led to a kink or a bend in the tracks near the Crystal City Metro stop. This afternoon, Metro says repair crews were there working throughout yesterday throughout the overnight hours and was able to fix that bend, meaning no trains need to single track through that area anymore. But Metro trains are generally moving slower right now because of the heat. The air conditioning is not working on some rail cars between Crystal City and Largo along the Blue Line.
