This Atlas HO Scale Code 83 Snap-Switch Manual Turnout features Code 83 nickel-silver rail with brown molded-plastic ties and a plastic frog. The turnout comes equipped with an attached manual, above-benchwork switch machine and includes joiners. The switch machine can be converted to electric remote control by replacing the manual switch machine with a Atlas Remote Switch Machines (sold separately). The 18" radius turnout also includes a 1/3 18" radius curve compensator track so for planning it equals one 18" curved section. For track planning purposes, track geometry matches the Code 100 Snap-Track line in terms of standard curve radii and section lengths.
