Deck with a wall and 4 barrels on it for switch machine --- N Scale

thingiverse

This is a deck with a concrete wall and four attached 55-gallon barrels that can be placed directly on top of the switch machine's slide. I also have one with a wooden wall behind the barrels instead of the concrete wall. You can print this deck with or without a hole in the front. The front hole can be used as an alternative to the peg for the control wire going to the turnout, making it less noticeable than the peg on the slide. If you choose to use it, simply cut off the peg from the slide and fill the hole, or download the file to print a top slide without a high peg. If the small hole in the front of the deck doesn't print with your printer, drill a hole of the correct size for your control wire .070 inches in from the end, centered. The deck with the wall and barrels is pushed back and forth to activate the DPST slide switch underneath it and also throws the turnout via the control wire to it. The DPST switch can also change the polarity of the frog. More information on the switch machine and how it operates can be found here: http://1fatgmc.com/RailRoad/3D-Printer/3D-Printer-Index.html
