We found that Metro's new trains are shaking homes.
It's happening all over our area. A woman who came to us for help just learned she's getting some results.
She told WUSA9's Pete Muntean it could be because we told her story.
It's a peculiar problem in the Petworth area of Northwest, D.C.
Hannah Martin's 80-year-old home rattles. The Metro's Green Line is underground nearby her home.
We first showed you this in February. After each rumble, we checked the Petworth Metro Station and every time it matched up with one of Metro's new trains.
The new trains are called the 7,000 series. The high-tech cars are heavier.
Metro just selected Hannah's house for a contractor to run vibration tests. A six-page packet arrived in the mail.
The contractor is a company called Wilson Ihrig. It has used sensors to test spots near rails before and so far, Hannah likes what she sees. But the proof will be in what she feels.
"I hope I find out my house is not at risk of foundation damage and I hope they figure out a way to stop the rumbling and the rattling," she said.
Hannah thinks it's no coincidence her home was selected. She thinks WUSA9's coverage of the issue played a big part.
This is not a short test. It takes almost a whole day, about seven hours. Hannah will have to take off work.
The test has not been scheduled for Hannah's house yet.
