  • all three main line tracks to be elevated on cork roadbed.
  • centers for the main lines are 4″, 6″, and 8″ from the front edge of the module.
  • all three main line tracks must end 1″ from either side of the module.
  • PECO large radius “Electrofrog” on all three main lines.
  • PECO medium radius “Electrofrog” permitted on Main 3 (Branchline) if it does not connect to Main 2.
  • any make and size may be used off the mainline tracks.
  • may be powered or handthrown on the main lines and/or industrial tracks.
  • double insulators separating one mainline from another mainline.
  • double insulators separating branch line from industrial spurs, with an on/off double pole – single throw (DPST) kill switch installed beyond the insulators.
Rolling Stock / Locomotive Power:
