“Reconstruction of the Metrorail system will continue over the weekend of August 28-30 with service adjustments on five rail lines beginning at 10 p.m. Friday and continuing through system closing on Sunday.
This weekend, Green Line trains will operate at regular weekend intervals. Red Line trains will operate every 20 minutes. Orange, Silver, Blue and Yellow line trains will operate every 18 minutes with Yellow Line trains operating to Mt. Vernon Sq only.”
“As part of the Authority’s investigation into the cause of an August 6th derailment, WMATA’s technical incident report to the Interim General Manager was released to the public today. To view report click here. The report will be the subject of a special Board of Directors Safety Committee Meeting on September 3.
“While the safety investigation is continuing and subject to review by the Tri-State Oversight Committee (TOC), the operations report reveals that the physical root cause of the derailment was the failure of fasteners to properly hold the rail securely. This was compounded by a lack of systematic, immediate review of data generated during the inspection vehicle runs,” said Safety Committee Chairman Michael Goldman speaking on behalf of the Board. “The investigation is ongoing to determine what caused those fasteners to fail. Further, the wide gauge track condition that went unrepaired was a contributory factor leading to the derailment that should never have occurred.”
According to the Incident Report, a Metro employee operating the Track Geometry Vehicle (TGV) that identified a “Level Black’ rail defect on July 9th mistakenly deleted the information about the defect from the exception report. That report was given to maintenance crews for scheduling immediate repairs to the rail system. Under the then-established protocols, the employee’s report with erroneously-deleted information was not subject to review by any Metro supervisor. The underlying data was not analyzed by other Metro departments for errors until after the derailment occurred on August 6.
“In reviewing the TGV inspection process, we have learned that the derailment was caused by a combination of human error and flawed Metro processes,” Goldman said. “While the employee believed he was deleting a routinely detected anomaly and not an actual rail defect, that such a serious error went undetected with no checks and balances in place reveals gaps in Metro’s safety policies and procedures.”
Still under investigation by Metro’s Safety Department is why the wide gauge condition and the broken fasteners went undetected by Metro track walkers who inspected this area of track on multiple occasions between the TGV run on July 9 and the August 6 derailment.
The Report also documents the immediate actions Metro has taken since August 6 to assure the safety of its passengers. Those include comprehensive inspections and immediate repairs of defects, the thorough review of the track inspection vehicle’s test results with an area manager prior to the generation of the final report for the maintenance crews, making track walker inspections more robust, and engineering reviews by outside experts.
In order to prevent such track safety failures from occurring in the future, the Board’s Safety Committee will review management’s actions and additional process and policy changes, as well as consider the need for “beefed up” safety reporting and consideration of protocols in other safety-critical areas to ensure maintenance crews have the most reliable information possible in order to schedule critical repairs. Further, the Committee will review how effectively the Authority’s System Safety Plan is meeting the safety culture needs of the organization and will examine if sufficient resources are available to meet the priority infrastructure inspection and maintenance requirements.
Wondering if you or anyone can shed some light on this: for the past week or two at least, the yellow line trains have been going quite slow over the bridge to and from Virginia. One morning, the conductor announced that the train was “required to go at a restricted speed between L’Enfant Plaza and Pentagon,” but other than that I haven’t seen any announcement or explanation. Does anyone know what’s going on?”
another reader writes:
“Metro has imposed speed restrictions on various portions of its track in response to the recent derailment. The red line train has gotten SUPER SLOW on certain stretches of track during my commute lately, resulting in noticeable delays. It seems reasonable to infer that the same defect that caused the derailment may be rampant throughout the system. Given that metro is subject to zero accountability, I worry that it may just be a matter of time before more people die.”
“Metro has implemented speed restrictions on curves throughout the system. That means trains are slowing to 35 mph to 40 mph as they approach a curve. The restrictions are in place as part of what Metro calls an “aggressive campaign” to inspect curved sections of track following the Aug. 6 derailment between the Federal Triangle and Smithsonian Metro stations.”

WMATA: Safety Hazards and Security Risks
Last Sunday, the Washington Metropolitan Area Transportation Authority hosted a safety exercise at the Stadium Armory metro stop. For three hours, firefighters and WMATA officials tested their communication and evacuation protocols. Shocking gaps were exposed and I left the event with little confidence in WMATA’s ability to fix them.
I’m the Advisory Neighborhood Commissioner for residents living next to the Stadium Armory stop and I was invited to participate in the exercise because of my ANC position. My participation that day was limited to standing around and taking pictures. I had asked WMATA to include neighbors in the exercise but my request was denied.
After WMATA denied my request, I reminded them of the sarin attack in Tokyo 20 years ago and the more recent attacks in London and Madrid. In a real world attack happens at Stadium Armory, how is WMATA going to communicate with neighbors? No response.
Instead, WMATA hosted a controlled safety exercise and this exercise demonstrated how WMATA staff fail even in a controlled environment. One of the participants in the Sunday exercise was in a wheel chair. Her wheel chair was too large to fit through the doors that are located between each car. WMATA’s solution was to put her in a smaller wheel chair. Slight problem. The lady couldn’t fit in the smaller wheel chair. WMATA’s solution was to put the lady and her large wheelchair in the front car. That made it easier for the firefighters to reach her and carry her out. (more…)
A couple readers report it happened around 7:20pm.
Another reader tweets us at 8pm:
“it is seriously awful. Four cars still in their crash locations, one in a pole.”
Update from AlertDC:
“MPD reports 14th St, NW from P St to R St, NW both directions are closed due to a 4-car vehicle accident / w non-life threatening injuries reported at this time, buses on this route are being diverted around the crash.”
“Metro’s fourth new 7000-series trainset will enter service Monday, August 17, on the Green Line.
Departing Greenbelt Station at 5:30 a.m. and Branch Avenue Station at 6:25 a.m., the new train will continue in service throughout morning rush hour and will be assigned to the Green Line.”
“Reconstruction of the Metrorail system will continue over the weekend of August 21-23 with service adjustments on five rail lines beginning at 10 p.m. Friday and continuing through system closing on Sunday.
This weekend, Yellow Line trains will operate at regular weekend intervals. Green Line trains will operate every 15 minutes and Red Line trains will operate every 20 minutes.
From 12:01 a.m. Saturday through closing Sunday, buses replace Orange Line trains between Eastern Market & Cheverly and Silver & Blue line trains between Eastern Market & Benning Road. Potomac Ave, Stadium-Armory, Minnesota Ave and Deanwood stations will be closed. Trains outside the work area will operate every 15-16 minutes.”

The Pain is Real: Your Metro Commute is Getting Worse
Last Thursday Metro sent a subtle signal that maybe I should take a day off. Unfortunately my boss felt otherwise. What started as a ‘minor’ derailment became two days of Metro competing with walking for the slowest way to get anywhere. It was bad and feels like part of a larger decline in Metro service. I was curious if that actually bore out in the data. Not only did it, but the decline is even more dramatic than I would’ve guessed.
The first half of 2015 had nearly twice as many delays compared to the same period in the past two years. Year to date Metro delays total over eighteen days. This is two and a half weeks. You could spend all your vacation days waiting for the Metro and still be waiting. This increase is partly due to a spike in delays this winter, but the spring and summer saw worse service as well.
It’d be nice if all these delays happened in the early hours of Sunday morning, since so many have long given up on taking the Metro anywhere on weekends. But the Metro is most likely to be delayed when you need it most. The heatmap below shows that delays are heavily concentrated just before and during commuting hours. Of course WMATA *tries* to run twice as many trains during rush hour. But there are more delays per train during that hour as well. Afterall, the benefit of more trains is debatable when you wait ten minutes for three trains to arrive at once.

*Data for July 2015 only goes to July 24th. So the numbers are likely even worse!
