The Faller Car System roadway offers complete design flexibility, so you can build wide or narrow streets, curves, moderate grades, straights, one-way streets, freeways or virtually any other modern road. Each set includes self-adhesive road surface in realistic colors, diecut cardboard base sections and guide wire. Base pieces interlock like a jigsaw puzzle, so installation is fast and easy. For custom applications, you can cut the various pieces to fit, or just install the guide wire in new or existing streets.
