Residents in some Washington, D.C., neighborhoods said Metro trains are rumbling through their neighborhoods so loudly that their homes are shaking. While they are blaming the newer and heavier 7000 series railcars, Metro said those cars are not the only ones creating a vibrational issue.
The new railcars are built with heavy steel and weigh about 2,000 pounds more than their older counterparts
Metro is still putting together a final report, but a recent letter from Metro general manager Paul Wiedefeld said some newer model trains are increasing vibration levels above Metro standards. However, Wiedefeld said higher vibration levels are coming in above standards with older model trains as well, and none of the vibrations are enough to cause any structural damage.
