The KATO 20-058 is the concrete-tie (PC sleeper) version of Unitrack's adjustable expansion track. It telescopes from 78 mm to 108 mm (3′′ to 4-1/4′′) to close awkward gaps when modifying or expanding a layout — an essential problem-solver for modern-image track plans. The molded concrete-tie deck features a lower, more prototypical ballast profile and matches the rest of the concrete-tie Unitrack family.
