On May 31, WMSC staff attended a full-scale emergency response exercise at West Falls Church Yard, where first responders and Metrorail personnel practiced responding to a simulated rail emergency.

That concludes today’s meeting. Our next meeting is scheduled for Tuesday, June 9, 2026.

The WMSC continues its oversight of WMATA's 8000-series railcar safety certification program.

[Washington Metrorail Safety Commission @MetrorailSafety]

This safety-critical use was a leading driver of the WMSC's oversight interest in this project when it was selected for in-depth review in 2022. Metrorail has indicated it will continue to rely on the improved manual back-to-back process.

[Washington Metrorail Safety Commission @MetrorailSafety]

In the past week, WMATA has indicated that it no longer intends to use AWIS for back-to-back wheel measurements.

[Washington Metrorail Safety Commission @MetrorailSafety]

Metrorail planned to use the Automated Wayside Inspection System as a means of real-time automated back-to-back measurements of the 7000 series rail cars through measurement stations that were to be installed at strategic locations throughout the Metrorail rail right of way.

[Washington Metrorail Safety Commission @MetrorailSafety]

The WMSC selected AWIS for in-depth review in August 2022 based on a number of safety considerations surrounding the project.

[Washington Metrorail Safety Commission @MetrorailSafety]

Station overruns continue to be elevated at certain stations, and the WMSC remains vigilant in its oversight. WMATA has undertaken a range of operational, training, and infrastructure mitigation measures to address overruns, and these efforts are ongoing.

The WMSC Systems Engineering work supports the WMSC's oversight work across train control, communication systems and signals state of repair and practice, and safety certification oversight.

This is a significant improvement from the issues noted in the 2025 Audit which led to the creation of this CAP. The WMSC commends Metrorail on this significant improvement on this important safety issue.
