The exchange with Wheatly/Silvano and subsequent bust by Stabler and his unit at Astor Place subway station tales place on a two track Island platform. This station is actually the now closed platform of the Bowery station. Astor Place is a local stop with two side platforms separated by 4 tracks. At one point the Bowery station mosaic on the wall is clearly visible, and it is impossible for two different groups of people using both subway entrances at Astor Place to meet at the island platform, they would be on two different platforms.
