What subway train stops near the Queens Center Mall?

The closest station is the Woodhaven Boulevard Station on the M (of the B-D-F-M, the orange line) and the R(of the N-R-Q-W, the yellow line). The E (of the A-C-E, the blue line) also stops at Woodhaven Boulevard at night (11 PM to 5:30 AM), when the M and R aren't running.

The Woodhaven Boulevard Station is on Queens Boulevard, right in front of the mall.

The second closest subway line is the 7 (the purple line) to Junction Boulevard. You'll exit the subway at the intersection of Roosevelt Avenue and Junction Boulevard. Walk about 0.5 miles south on Junction Boulevard (you will know which way is south because the next intersection will be Junction Boulevard and 40th Road. If you walk 1 block and reach 38th Avenue, then you've gone north). When you reach the Long Island Expressway, the mall will be on your right side.
