It’s been a rough morning for Metrorail. First, a dangling power line prompted major delays on the Red Line, and now a cracked rail is causing minor delays on the Orange Line.
The cracked rail is on the inbound track of the Orange Line between East Falls Church and Ballston. Repairs are underway and are expected to be completed before rush hour.
While repairs continue, trains will be single tracking between East Falls Church and Ballston. According to WMATA spokesman Dan Stessel, at noon there are only delays of about five minutes because trains are currently operating on an off-peak schedule.
The cracked rail is reportedly “almost certainly” the result of the recent temperature drop. Stessel explained that because metal expands and contracts with temperature fluctuations, over time that can cause cracks in the rails.
