Metro expects to submit a required testing plan Thursday to its oversight agency that would be the first formal step toward getting more than half of its trains back into service.

The plan will propose a testing or detection process that would routinely check for a wheel defect that has afflicted several of Metro’s 7000-series rail cars over the past four years. General Manager Paul J. Wiedefeld said the transit agency will submit the plan to the Washington Metrorail Safety Commission, a move aimed at ending a train shortage that has severely reduced rail service for nearly three weeks.

Unfortunately those tracks were not tied in just yet, so they couldn't have.


Phase II of the Silver line is in fact tied in, its been that way for at least two an half years. it's only the signal and train control system that is not fully operational. Nothing physically preventing WMATA from dead heading any rolling stock along the unopened part of the Silver line.
And let me guess... crews are all up and down the line tying and testing that equipment... and isn't it still Metro Washington Airport Authority track until it's officially handed over, tested, and deemed ready? I think the track is technically off limits.

Wrong gauge by a 1/4 inch.


That 1/4 of an inch is a minor detail when compared to the load gauge that's wrong by 1 foot 1 1/2 inches.

Today, Nov. 16, Adam Tuss did a series of tweets from a Metro repair facility about the status of the 7000 series, including lots of photos. I'll post a link to his first tweet and folks should be able to find the rest (unfortunately he did not create a thread of posts, just one off's). https://twitter.com/AdamTuss/status/146 ... 55974?s=20

First tweet to last including the link to the tweet in your post. I am posting the links to all of them so folks don't have to search for them in the future.

This is a “wheel set assembly” from one of the 7000 series. This is how they measure @nbcwashington

This is a 7000 series “truck” which holds 2 wheel sets. There are almost 3000 wheel sets in the 7000 series fleet. It takes about 6 hours to inspect one train. #wmata @nbcwashington

Metro staff says it is very obvious from measurements when a wheel set is not right. It then gets a red tag and gets sidelined until it is fixed. That whole process can stay within the maintenance department and not be raised to a higher level #wmata @nbcwashington

Underneath the 7000 series. This is pretty cool for a transit nerd #wmata @nbcwashington

They can measure these right here without actually taking the trains apart #wmata @nbcwashington

Metro’s GM says he is “not going to set a date” to get the 7000 series back on the tracks. Says he doesn’t want to rush anything back. The data will drive the date #wmata @nbcwashington

Metro maintenance teams told us today they do have a process for “frequent failures” that can get escalated to a higher level. But they would not say if the 7000 series wheel issues fell into that category #wmata @nbcwashington

Metro has been running two test trains of the 7000 series railcars on the tracks for a couple of weeks - I asked Metro’s GM today if there have been any issues reported and if he’s concerned those trains might not ever make it back. @nbcwashington #wmata

I know this will be a shock to many but the 7Ks will be out at least through the end of the year. We're now in day 15 of the 12 day test period of the new 7K inspection regime with nary a word of progress. No timeline is given for service restoration because of safety (not because they want to avoid any sort of accountability whatsoever).
