A fire at the Arlington Cemetery Metro station caused major delays on the Blue Line Saturday as thousands visited the Washington, D.C. area for Memorial Day weekend.

The Arlington County Fire Department said just before 5 p.m. a train's brakes were on fire at the Arlington Cemetery station.

A spokesperson for Metro said the "small" fire was extinguished and it was caused by extremely hot brakes.

There were not passengers on the train at the time, Metro said. The train off-loaded at the Capitol South station.

Blue Line service was restored about 7:10 p.m. and Metro said riders should expect residual delays.

Trains were single-tracking between Pentagon City and Arlington Cemetery for about an hour after service was suspended for a time between the Rosslyn and Pentagon City stations.

The Silver Line also experienced delays in both directions because of the issue.

Arlington County fire officals said one injury was reported, but later said that injury was not related to the fire.
