Construction of the first phase of Metro’s Dulles rail line is underway in Northern Virginia and there’s buzz about what the addition of the service will mean for the region.

Bisnow, a local promotional business group, is holding an event titled “What’s Next in the Dulles Corridor?” on Monday, Sept. 19 at 7:15 a.m. at the Ritz Carlton in Tysons Corner.

The Dulles rail line will eventually stretch from Tysons Corner to Dulles International Airport and Loudoun County. It will include 11 stations and 23 miles of new track. The first phase is under construction and expected to be completed in late 2013. Construction has not yet started on the second phase.

The Bisnow event will include developers, businessmen and residents looking at a variety of questions that surround the new Dulles line.

A flier says the participants will look at — What’s the status of the second phase of the project? Where do things stand on the six stations and five parking garages in the first phase? Who is paying for the infrastructure and how will it impact commuters? How much will the tolls be on the Dulles roadway? With three stations planned for Reston and Herndon, how will that affect those areas?

The panel includes former Congressman Tom Davis; Patricia Nicoson, president of the Dulles Corridor Rail Association; Arthur Fuccillo, an executive vice president at Lerner Enterprises; Pete Otteni, a vice president at Boston Properties; and John Schlichting, an executive development officer at the JBG Cos.
