This KATO HO Unitrack R370-22.5 track set adds four curved sections to model railroad layouts that use KATO's HO UNITRACK system. Each piece forms a 22.5-degree curve with a 370mm (14 9/16-inch) radius.
Use these sections to shape smooth, consistent curves while planning or expanding an HO layout. The four-piece count makes it easy to add a complete curve segment to a KATO UNITRACK arrangement.
