MTH Electric Trains O Scale 3-Rail Scale Trax makes setting up a realistic layout fun! This three-rail track features nickel silver rail and a smaller, blackened third rail for realism and reliable performance.

Durable ABS molded plastic ties give the track a realistic appearance. Available Scale Trax flex track allows you to add more realistic track arrangements to your track plans. Scale Trax is compatible with all O Scale 3-rail trains, but make sure to note how sharp your curves are since many larger O Scale trains need wider O-31 and larger curves.
