This is a set of PCB ties for turnout construction. They are fully compatible with the Fast Tracks N Scale product. These ties are made from high quality fiberglass and are gaped, drilled and tinned. Cut the ties to length with an old pair of diagonal cutters or similar and insert them into the Fast Track jig. Be sure to check the length as you cut since the exact length varies depending on the point size. Also use an old pair of diagonal cutters as fiberglass will dull cutters. Since they are already tinned they solder easier then bare copper ties.
