brio straight rail for electric trains to go under bridges

thingiverse

I don't know exactly what happened in the minds of Brio engineers, but somewhere during the electric train development process, they completely forgot about their bridges' heights. Let's just say those bridges are not even remotely high. Edit: A version has been added with holders that prevent rail sliding under the bridge. Years pass and products evolve - I get it. But Brio tracks remain the same standard. When buying an electric train in its box, the packaging makes no mention of a new engine being too big to fit under existing bridges or navigate through tunnels. That's not okay. Thanks to strepmud for making the necessary modifications possible. Within minutes, we created a rail that puts everything right back where it belongs. Although imperfect, this modification allows you to use all sorts of bridges without needing any modifications at all. Keep in mind that the modified rail is delicate, so make sure to adjust its placement so the engine doesn't touch the bridge - it's a pretty tight fit. Because of this issue, we've also created a 3/4-sized version (you'll need two for double-decker bridges) and even an extension piece you can insert between them, making navigating through quadruple, quintuple, or more bridges possible. If anyone wants to send wood-filled filament my way... Print Settings Rafts: No Supports: No Resolution: Print as high as you possibly can - .2 mm should be just fine. Notes: The center of the rail where the wheels meet is basically unsupported. To get the best results, make sure your bed is perfectly level, print without a raft or supports, and remove the part very carefully - use caution when handling it. If using glass, allow it to cool first for easier removal.
