Comes with a 1/3 18 radius section, making the curved leg equal to an 18 radius section. To add a passing track and siding, simply replace a 9 straight section. When replacing an 18 radius curved section with an Atlas Snap-Switch, add a 1 1/2 straight section to the opposite side.

These switches have a manual switch machine attached so you can throw (changing the direction of the rail), from the switch itself.


  • 18 Radius Snap-Switches
  • Black Ties, Nickel Silver Rail
  • Designed for above or under-table switch machine
  • Plastic Frog (cannot be powered)
