WASHINGTON (WUSA9) -- Last week, we told you that the opening date for the first phase of Metro's Silver Line may have been pushed back to January after concerns over a contractor's use of the Automatic Train Control system on the Dulles Corridor Metrorail Project.
In a letter, Metropolitan Washington Airports Authority President and Chief Executive Officer John E. Potter wrote to Department Of Transportation Administrator Peter Rogoff that the testing work done by contractor Dulles Transit Partners and subcontractor Alstom Signaling, Inc. "is not acceptable, and corrective actions have been initiated."
Potter continues by saying MWAA's project staff and the Washington Metropolitan Area Transit Authoritiy were "monitoring all such actions."
Potter ends his letter to Rogoff with "Please be assured we will not accept any Phase 1 product from Alstom, or any other DTP subcontractor, that has not met all safety requirements. Vigilant oversight of all Project activities will be conducted by our staff and fully shared with WMATA, FTA/PMOC and TOC. In no case will safety be compromised."
Work on the second phase, which will run Metrorail into Loudoun County past Dulles Airport, is expected to begin in July.
