In normal train coaches General Waiting list gets preference over Tatkal WL. In these trains if extra coaches are attached at temporary augmentation during Summer/Winter rush period then again GNWL has preference over Tatkal WL. However, if extra coaches are attached at last minute to clear rush (EX CLUDING summer/winter rush as normal measure) then Tatkal WL will have preference over GNWL. In fact CR and WR have now introduced last category extra coaches in few selected trains duly notified where Tatkal has preference over GNWL and as thus all Tatkal WL are being cleared accordingly.
