Old thread, but worth revisiting. I pass through this area often.
The bush has gotten a bit more busy over the past few months. Aside from WM's MSW operation (yields anywhere from 5 to 15 cars a day, 5-6 days a week), there's a customer that gets an occasional boxcar at the end of stewart ave (street dead ends right at the track, acts as a loading dock), and someone getting cables and pipes at the front of the old Bushwick yard, btw. Morgan ave and kings lumber. They come in with a truck and rented crane to unload the gons and lumber flats. There seem to be 4-5 cars in there every time I pass. Kings lumber now has a ready mix facility that receives some of the tilcon stone cars.
I believe western beef is also still taking reefers, though their siding is a bit away from the streets.
The large, newish building on Varick ave opposite WM which had a new siding put in maybe a year ago still has not taken a car, so far as I can see. Also haven't seen tankers next to that building east of Morgan ave in a long time. Overall though things seem up, just on the ready mix customer alone.
