WASHINGTON — More than a year after people living along the Green Line in parts of Northwest began complaining that Metro trains might be shaking their homes, Metro has yet to provide any conclusions about the vibrations to the D.C. councilmember who represents the area or those affected by the shaking.
Metro’s preliminary findings will be shared “very shortly,” General Manager Paul Wiedefeld said Thursday.
Metro hired a contractor to test some of the homes in the Petworth area for vibrations and any relationship to Metro’s trains.
Councilmember Brandon Todd’s office said Metro has not provided any details about the results of the testing, despite numerous requests for information.
Wiedefeld would not say whether the investigation has led to any suggested changes for Metrorail operations.
“When we get out with the findings, you’ll see all that,” he said.
Federal Transit Administration inspectors suggested earlier this year that broken fasteners and increased forces from braking and acceleration may have contributed to an increase in vibration. The investigation also included a look at whether the new 7000 Series trains created special vibration issues due to weight, resonance or other causes.
