These switches have a remote control switch machine attached so
you can wire the switch to be thrown (changing the direction of
the rail), from your control panel, rather than from the switch
itself. Comes with a 1/3 18 inch radius track section, making the
curved leg equal to an 18 inch radius section. To add a passing
track and siding, simply replace a 9 inch straight section. When
replacing an 18 inch radius curved section with an Atlas
Snap-Switch, add a 1 inch straight section to the opposite side.
All Atlas Code 100 has black ties and nickel silver rail.
