Kato Code 80 Flexible Track is perfect for expanding a new or existing layout. Its flexibility allows you the freedom to make freeform track layouts that may not quite fit the Unitrack system of roadbed track. The appearance of the Code 80 rail and ties matches that used on Unitrack sections. Flexible Track features nickel-silver rail and either wood or concrete ties. Flexible Track sections are each 31-13/16" 808mm long and can be joined to Unitrack or other makers' Code 80 flex track using conventional rail joiners.
