WMSC reviews multiple safety investigations, including a string of improper door operations; commission adopts reports
Summary
The commission reviewed eight investigation reports including four improper door operations; staff described causes and corrective actions and commissioners unanimously adopted the reports as presented.
The Washington Metrorail Safety Commission heard presentations on multiple safety investigations and, after the presentations, voted unanimously to adopt the eight reports presented at the Sept. 16 meeting.
Improper door operations
WMSC investigators summarized a set of improper door operation events reported since ADO (automatic door operation) activation. Causes cited across the cases included human error, loss of situational awareness, noncompliance with written procedures, and fatigue. Investigations reviewed closed‑circuit‑television (CCTV) footage, event data and interviews.
Examples presented by WMSC staff included:
- A Bethesda incident (11/01/2024) where a train that had stopped short of the platform had its lead car door manually opened by the operator and a rail supervisor; the simultaneous uncoordinated actions contributed to an improper door opening while the train was not fully berthed.
- A Rockville event (12/13/2024) in which an operator activated the non‑platform side door open button after an alarm appeared on the train control display; the operator reported they were unaware how isolation affected alarms.
- A Franconia‑Springfield event (12/21/2024) where a train stopped 56 feet short of the A‑car marker and two railcars remained off the platform; the operator later reported the issue and a supervisor was dispatched.
- A Pentagon event (12/29/2024) in which an operator said they inadvertently activated the right‑side door open button while gesturing; the operator reported 3.5 hours of sleep in the prior 24 hours, and fatigue was cited as a contributing factor.
Investigative findings and corrective actions
Investigators recommended that MetroRail preserve all communications (including Microsoft Teams chats) for future reviews and incorporate instant messaging in event investigations. MetroRail implemented corrective measures that staff described: targeted refresher training for personnel involved in the events, broader reminders to operators to use the point‑and‑call method, hourly announcements by controller staff during some periods, and a vehicle operator outreach program to increase compliance on door operations.
Other investigations
The commission also reviewed other safety investigations including (1) a fall behind a parapet wall at McPherson Square where address confusion delayed emergency responders; (2) a trip‑machine derailment while negotiating a 4% incline and curve that resulted from switching from travel to work mode; and (3) two collisions at Minnesota Avenue Station in March 2024 in which roadway maintenance machines struck an emergency trip station then a temporary handrail that had been installed after the first collision. The Minnesota Avenue reviews led MetroRail to require engineer drawings and post‑installation verifications for any changes affecting the dynamic envelope.
Vote
After the presentations, the commission voted to adopt investigation reports Whiskey391 through Whiskey398 (numbering as corrected in the meeting) by voice vote; the chair announced the vote was unanimous, 5‑0.
Ending
The chair thanked staff for the investigative work and said adopted reports will be posted. Commissioners reiterated the importance of reporting, preserving communications and ensuring supervisory and procedural clarity to reduce recurrence.
