? Custom Line switches are made to be used with the Atlas Under-Table Switch Machine (#150-65 or 66) or a ground throw. Switches feature full-length ties and a double-ended throwbar, allowing placement of the under-table switch machine on either side of the switch. ? Atlas popular and traditional Code 80 N Scale track features nickel-silver rail on black plastic ties. Switches feature refined and narrow flangeways at the frog and guard rails, and positive mechanical attachment of points. The difference between Standard and #6 switches is the angle at which the curved piece of track splits from the straight piece. Because the rails of Standard switches split at a sharper angle than #6 switches, they create a sharper curve and work better in smaller spaces. ? ? ?
