3 Barrels on Deck for Switch Machine --- N Scale

thingiverse

This is a deck with 3 attached 55-gallon barrels that can be placed directly on top of the switch machine's slide. You can print this deck with or without a hole in the front, providing flexibility to suit your needs. The front hole serves as an alternative to the peg for the control wire going to the turnout, offering a more discreet solution than the peg on the slide. If you choose to use it, be sure to cut off the peg from the slide and either fill the hole or download the file to print a top slide without a high peg. For reference, visit: https://www.thingiverse.com/thing:4279017 If the small hole in the front of the deck doesn't print with your printer, simply drill a hole of the right size for your control wire - .070 inches from the end and centered. The deck with barrels is designed to be pushed back and forth, activating the DPST slide switch beneath it and also triggering the turnout via the control wire connected to it. Additionally, the DPST switch can reverse the polarity of the frog. For a deeper understanding of how the switch machine operates, visit: http://1fatgmc.com/RailRoad/3D-Printer/3D-Printer-Index.html
