N Scale - 12 ft. dia. Fuel or Water tank on a deck for the switch machine.

thingiverse

This is a deck with a 12 foot dia. fuel or water tank that can be placed on top of the switch machine's slide. You can print out either a slide that goes on top of the DPST switch and under this deck with or without a vertical peg to attach the control wire that goes to the turnout. If you use the hole on the front of the deck then print the slide without the peg that you can find here .... https://www.thingiverse.com/thing:4279017 The deck with the fuel/water tank is pushed back and forth to activate the DPST slide switch under it and also throws the turnout via the control wire to it. The DPST switch can also change the polarity of the frog.
