Z scale is one of the smallest commercially available model railway scales (1:220), with a track gauge of 6.5 mm / 0.256 in . Introduced by Märklin in 1972, Z scale trains operate on 0-10 volts DC and offer the same operating characteristics as all other two-rail, direct-current, analog model railways.
