The Connection Newspapers has this informative article on the current state of Phase 2 of the Silver Line, which will connect with Oak Hill. Principally, Loudoun County has to decide whether to play or not. Excerpt:

AS THE DEADLINE NEARS, there is growing ire on either side of the debate. Right wing groups have attacked the Silver Line project as a tax. According to the Washington Post, a group funded by the Koch brothers, a pair of conservative Kansas billionaires, have conducted robbo calls in the county saying that funding the Silver Line will mean a “bailout for developers.”

Clark and other opponents claim they have faced “strong-arming and veiled threats by some developers and elected officials.”

Stephen S. Fuller, the director of the George Mason University’s Center for Regional Analysis, prepared a report in March which warned, if Loudoun does not go along with the Silver Line, “the county’s economy will grow more slowly, driven by gains in lower value added employment and imported income earned by residents commuting to jobs located outside the county.” He saw a loss of $11.2 billion in foregone economic activity in 2030 and $25.6 billion lower gross county product in 2040 “than had Metrorail been extended to the county as planned.”
