Metro investigators spent Wednesday trying to figure out why a train went partially off the tracks inside the Rosslyn station Tuesday.
Two Metro employees were placed on paid administrative leave following Tuesday’s train derailment on the Blue Line.
Metro chief spokesman Dan Stessel told The Washington Post the two employees placed on leave will be tested for drug and alcohol use. Stessel said this is the standard procedure for workers involved in particular situations.
Metro is still investigating what caused one set of wheels on the first car of a Franconia-Springfield-bound Blue Train to derail at a Rosslyn station on Tuesday evening.
None of the 1,000 passengers aboard the train at the time were hurt.
Crews worked through the night and had Metro service restored in time for Wednesday’s mornings commute.
