Metro has fired six employees after an investigation into the train derailment that took place at East Falls Church station on July 29, and more employees are in line to face consequences.

The incident involved two Silver Line train cars that derailed with 75 passengers on board, one of whom requested treatment for minor injuries. Metro General Manager Paul Wiedefeld announced in August that WMATA would open up a criminal investigation into the derailment, after information uncovered during an administrative review of the incident raised “potentially serious concerns.”

Wiedefeld said in a statement given to WMATA board members this morning that the internal review discovered some employees in the track department “falsified track inspection records.”

He went on to say that the review “revealed a disturbing level of indifference, lack of accountability, and flagrant misconduct in a portion of Metro’s track department which is completely intolerable.”

He added that it’s “reprehensible that any supervisor or mid-level manager would tolerate or encourage this behavior, or seek to retaliate against those who objected.” In addition, he said, it’s “entirely unacceptable” that any employee would go along with this activity.

In total, Metro has or will discipline 28 employees—nearly half of the track inspection department. The six fired employees include four track inspectors and two supervisors.

Jackie Jeter, the head of Metro’s largest union, says it will “probably” fight the disciplinary action, according to Adam Tuss of NBC Washington. She said she doesn’t believe the derailment findings “are necessarily being presented accurately by Metro.”

While no arrests have been made, prosecutors were briefed on the findings and “are taking the matter under advisement,” Wiedefeld said.
