Atlas HO scale - Brown ties, nickel silver rail.
Custom-Line Turnouts are prototypically accurate, featuring blackened metal frogs and rivetless switch points that provide superior electrical conductivity. These turnouts can be powered using an under-table switch machine or standard remote and manual code 83 switch machines. All Custom-Line Turnouts have the same geometry as the current Atlas code 100 versions, for drop-in installation in Atlas' and other layout plans.
Please note that you cannot substitute a Custom-Line for a Snap-Switch as their geometries are different."
