The Z series Shinkalion models essentially upgrade the play patterns of the originals. The main focus of the line is interchangeable parts with the Zailiners, non-shinkansen train units that separate into alternate limbs. To accomodate this new play pattern, the Z Shinkalions now resort to partsforming to allow interchangeable limbs. Due to this partsforming feature, the Z Shinkalions are far more articulated than the Plarail and Plarail DX Shinkalions, featuring many more joints in places that are omitted in the originals. The Z Shinkalions are still compatible with the plarail track, but lack powered units like it's predecessor. In train mode, the Z Shinkalions have shorter cars and each car now has a realistic number of 8 wheels each.
