SUPERTRAIN TO DULLES

And only for about the cost of 2 weeks in Iraq.

Federal regulators have approved a long-awaited extension of Metrorail to Tysons Corner and Dulles International Airport, virtually assuring construction of a $5.2 billion project that regional leaders say is crucial to ease congestion and spur economic growth in Northern Virginia.

By signing off on the project, the Federal Transit Administration reversed its position of almost a year ago, when its regulators declared Dulles rail unqualified to receive $900 million in federal funding, citing cost overruns, delays and concerns about management. The project now heads to U.S. Transportation Secretary Mary Peters and the Office of Management and Budget for final approval. But the transit agency's action is widely viewed as a critical achievement that essentially guarantees the federal funding. Without it, the project would have died, state and regional officials said.
