4-car Q sets were formed from March 1997 for use on Kodama shuttle services running between Hakata and /, and also for use on some Hakata-Minami Line duties. These sets had no Green car. The last remaining unit was withdrawn in September 2001. Set Q3 remained as a static training set at Shin-Shimonoseki Station until 2009, when it was replaced by 100 Series set P2.
