The Washington Metropolitan Area Transit Authority suspended rail service between Rosslyn and the Pentagon for a second day Thursday after a train derailed on the Blue Line near Arlington Cemetery Tuesday evening.

WMATA officials announced the reductions as a result of the “ongoing investigation,” and free shuttle buses are replacing trains between Rosslyn, Arlington Cemetery and Pentagon stations. Hundreds had evacuated the train after it partially derailed Tuesday just before 5 p.m., WUSA9 reported.

WMATA officials said Tuesday night they would implement single tracking between Clarendon and Foggy Bottom, which will also continue through at least Thursday.

“Customers should expect delays on the Orange and Silver lines due to the single tracking,” WMATA said in a release.
