Atlas N Scale Custom Line No. 6 Turnouts feature nickel-silver rail with molded black ties. They are designed to be used with the Atlas Under-Table Switch Machine (150-65) or a ground throw. Unlike Atlas Standard Line turnouts which have shortened ties to allow for switch machine attachment, Custom Line No. 6 Turnouts have full-length ties. A double-ended throwbar allows you to place your under-table switch machine on either side of the switch. This Custom Line No. 6 Turnout is part of the line of Atlas N Scale track.
