Metro consultants confirm resident fears regarding noise and vibrations

  • Published in Local

metro logoA consulting firm hired by Metro has confirmed local residents’ concerns about Metro’s new 7000 series trains – they are louder than the old ones and may have a tendency to vibrate more, shaking nearby homes.

Consultants from Wilson Ihrig, the firm Metro hired for the study, said in the report posted online March 24 that in all but one residential site tested, vibration from the trains was higher for the 7000 series, than the older ones. The study concluded this by measuring ground-borne vibration in houses a few hundred feet from the track centerline when a train passed by.

The report’s authors said some Metro trains violated the organization’s design criteria by go over the recommend vibrations for nearby homes.

New Metro cars blamed for continuing problems

  • Published in Local

metro logoWASHINGTON — A Washington Metropolitan Area Transit Administration rail technician says the increased power needs of Metro’s 7000-series cars – the system’s newest rail stock – is damaging the system that transmits electric power to trains, resulting in problems – including fires – that can cause delays.

“The fires are caused by these current draws by the 7000s,” Metro Automatic Train Operation technician Jack

Bounthong said in October. “We never had a fire incident before we got the 7000s.”

Bounthong explained how trains made up of 7000-series cars are causing track fires and other damage to the propulsion system that powers the trains. The 7000-series’ increased power needs are also responsible for delays because the increased power use can generate so much heat that sensors located near crossover tracks (where a train can switch from one track to the other) can erroneously sense a non-existent train on the opposite side of the tracks and send incorrect signals to other trains, as well as the Rail Operations Control Center.

“Now you got trains backing up – that’s why you get those delays,” he said, “because signals go in and out – the train will sit at the signal for no apparent reason.”

Metro discovers new shocking problem with 7000 series cars

metro logoA component in Metro’s newest rail car series is breaking prematurely and its manufacturer has designed a modification to fix it, Metro spokesperson Dan Stessel said.

David Stephen, spokesperson for Amalgamated Transit Union Local 689, said a mechanic reported he was shocked while inspecting part of the underside of the 7000 series rail car Sept. 17. He called on Metro officials to pause inspection of 7000 series rail cars until after briefing railcar mechanics on potential hazards of inspecting and repairing the newest series of railcar.

“As a result of this incident, ATU Local 689 is demanding Metro not bring any 7000-series trains into the shop until all employees that come in contact with them are properly informed on the potential for hazards, and training is given on bringing trains to manufacturer specification (to date, railcar mechanics have yet to be trained on maintaining 7000-series cars),” Stephen said in a statement.

Stessel confirmed the mechanic was shocked while inspecting a railcar, adding the incident occurred at West Falls Church Rail Yard. He said the mechanic was not injured.

Manufacturer modifying Metro 7K rail cars after electric shock incident

Rail car part deteriorating prematurely, Metro official says

metro logoA component in Metro’s newest rail car series is breaking prematurely, and their manufacturer has designed a modification to fix it, Metro spokesperson Dan Stessel said Thursday.

A mechanic reported he suffered electrical shock while he was inspecting part of the underside of the 7000 series rail car at West Falls Church Rail Yard on Sunday, Stessel confirmed. This was related to the deteriorating rail car part, the ground brush. However, he suffered no serious injury. The mechanic said he did not want medical attention. However, Metro staff took him to a local hospital.

Stessel confirmed a problem is developing with the 7000 series trains, the newest in the Metrorail fleet.

“Yes, there were defective wires, there was a problem within the ground brush assembly itself and that problem is mitigated by the safety bulletin we put out,” Stessel said.

NTSB first warned subway system about danger following 2004 incident

metro logoWASHINGTON – The National Transportation Safety Board says Metro’s 1000 series cars have to go and a Metro spokesman claims they will be gone in a few weeks.

But the problem goes back more than a decade, to 2006 when the NTSB first told Metro managers they might need to replace the aging cars following an investigation into a 2004 acciddent.

Meanwhile Metro continues to operate 34 of its original rail cars to transport passengers, despite the National Transportation Safety Board’s 2010 recommendation to remove them.

Pop ups popping up at Grosvenor Metro stop

PHOTO BY MARK POETKER Commuters at the Grosvenor-Strathmore Metro stop aren’t rushing to their cars at the end of the day quite as quickly as they normally do. Between now and the end of June, the area between the parking lot and the entrance to the Red Line train is home to pop-up stores selling food, clothing and flowers on Wednesdays, Thursdays and Fridays between 3:30 p.m. and 7:30 p.m.

What started as an idea to demonstrate to commuters how they plan to redevelop the station area in a few years, Fivesquares Development in Washington, D.C., took a retired 4,000-series Metro car and cut it up into numerous pieces, which currently serve as home to the popup stores, which opened May 17.

“We wanted to bring life to the plaza,” said Ron Kaplan, principal at Fivesquares.

Metro Examines Fasteners

Vibrations on the Green Line and possible ties to derailments explored in subway

WASHINGTON – Metro’s chief safety officer, Pat Lavin, said Tuesday Metro is investigating a possible connection between Metro rail fasteners and shaking houses located above the Green Line.

Inspectors say some of the fasteners may have been less than a day old when discovered broken.

“I wouldn’t say the rail clips are defective,” Lavin said. “If there’s an issue with a certain clip or a certain batch, those would be explored.”

Residents of D.C. neighborhood Petworth, located above the Green Line, complained to Metro executives last year they believe trains are causing their houses to shake and to vibrate, Metro said.

WASHINGTON – Metro is investigating residents’ complaints that trains are causing damage to D.C. homes, according to a spokesperson.

Meanwhile, the organization has been looking for rail fasteners that can hold more weight.

Spokesperson Richard Jordan said in a statement Metro is investigating the claims as well as whether Metro even has a role in the vibrations that those D.C. residents reported.

“Metro has retained an independent third-party expert (Wilson Ihrig) to conduct field measurements following complaints of vibration from residents along a specific section of the Green Line,” Jordan said Wednesday. “While Metro has not confirmed the cause or severity of these vibrations – or even confirmed that the complaints are Metro-related, we have committed to conducting independent testing to determine next steps.”
