N Scale - 8 ft and 10 foot decks in front of wood wall.

thingiverse

This is an 8-foot-long or 10-foot-long deck with a wood wall at its back. You can place whatever you want on this deck, and it sits atop the switch machine's slide. You can print out either a slide that fits over the DPST switch and under the deck, with or without a vertical peg to attach the control wire heading to the turnout. If you use the hole in front of the deck, then print the slide without the peg found here: https://www.thingiverse.com/thing:4279017. The deck is pushed back and forth to activate the DPST slide switch beneath it, as well as to throw the turnout via the control wire attached to it. The DPST switch also changes the polarity of the frog. More information on the switch machine and its operation can be found here: http://1fatgmc.com/RailRoad/3D-Printer/3D-Printer-Index.html. Prints were created using an Ender 3 Pro with Cura set to 'Super Quality' in the 'Profile' settings, along with a stock .4 nozzle.
