Testing is under way, at least, at the temporary railyard

Photographer Tracy Collins went out to the Vanderbilt Yard today and reports: "It appears that the MTA is at least testing the new 'temporary' rail yard that's being constructed for the proposed Atlantic Yards development."

The railyard is in the eastern third of the Vanderbilt Yard, between Carlton and Vanderbilt avenues (and Pacific Street and Atlantic Avenue). The longstanding railyard, between Fifth and Sixth avenues, would become part of the arena site. (Photo 1, 2)
