MTH Electric Trains O Scale 3-Rail Real Trax roadbed-style track makes setting up your layout easy! This track features built-in roadbed for easy setup on any surface. The durable plastic roadbed (you can stand on it) comes with three rails attached, a blackened center rail and all rail joiners in place. It's molded in a realistic gray color to simulate real track ballast and has under-track electrical contacts for reliability. RealTrax is compatible with all O Gauge 3-rail trains, but make sure to note how sharp your curves are since many larger O Gauge trains need wider O-31 and larger curves. RealTrax can be connected to traditional tubular track using an adaptor section. Check out the line of MTH Electric Trains RealTrax 3-Rail O Scale track and accessories.
