This Atlas Code 83 Custom-Line Mark IV Turnout features nickel silver rail and brown plastic ties that match other Atlas Code 83 trackage. This turnout can be set up as a remote or manual switch with your choice of switch machine (sold separately). The turnout comes equipped with a metal frog that can be powered if necessary for your layout, and a throw bar with the extension on both sides. Custom Line turnouts feature Code 83 low-oxidation nickel silver rail with a realistic cross-section and can be used with a variety of switch machines or ground throws (sold separately). Each turnout includes four rail joiners. You can use the frog power contact option to energize the frog and prevent loss of power when a locomotive is passing through. For track planning purposes Code 83 Custom-Line Mark IV Turnouts are not interchangeable with Atlas Snap Switch turnouts in layout plans. See the entire line of Atlas HO Scale Code 83 track.
