 DATE: When he arrives in Brighton Beach on a December night in 1991,  Neil is seen noting where the closest subway stop is. The Brighton  Beach station sign shows a Q in a yellow circle and a Q in a yellow  diamond. But the "Q diamond" train was operating on that line for  only a few years starting in the early 2000s. Prior to that, the  Brighton Beach stop serviced the "Q circle" and the D trains.
