time, riders from central Queens had a one-seat ride to southern Brooklyn destinations and Coney Island. The QJ was added as a rerouting of the old QT, combined with an extension of the old J Jamaica Express, entering Manhattan via the tunnel and extending via the BMT Jamaica Line to 168th Street.

It operated only during rush hours, running skip-stop with the QJ on the BMT Jamaica Line east of Broadway Junction and then local into Manhattan. In Brooklyn, the KK (rush hours) and QJ (other times) replaced the JJ service, which was discontinued. The KK served "A" stops on the skip-stop portion of the BMT Jamaica
