#WMATA radio transmissions do appear to suggest that damage to Metro power infrastructure may have been intentional, and is what's causing this service suspension. Few details available yet as to power restoration timeline.
#WMATA offloaded Red Line train 114 due to a propulsion issue. The train is now being "Proceeded" - that is, a lookout in the lead car is radioing back to someone further back in the train so the train can move - in order to get it back to a rail yard.
Delays, both directions.
The #WMATA ROCC appears to have found a clever way to route around the disabled train just outside Grosvenor. Inbound trains are traversing via the pocket track; outbound is unaffected.
#WMATA has posted its FY22 Q3 financial report, dated May 13, 2022. It was posted on July 29, 2022. This period covers January-March, 2022.
Among other derailment investigation cascading effects: #WMATA has overhauled fewer of its older 2000/3000-series railcars with new components because they're needed for service.
As of March 2022, 82 of 182 6000-series railcars were potentially available for service.
What're y'all's #WMATA questions? Maybe I have some answers...
In its simplest form: Under some conditions/circumstances - which #WMATA, WMSC, and NTSB are still investigating - the wheels on some 7Ks were moving out from where they should be. Daily inspections are meant to catch that early if it happens again.
Not enough railcars:
* Most of the fleet are the 7000's (~60%). All but 8 of those trainsets are grounded b/c Oct 2021 derailment
* Not all ~180 6Ks (~15%) are back in service after two trains pulled apart in 2020
