Modular Track Switch System for LEGO® Trains - KICKSTARTER Project

LowaLowa FloridaMember Posts: 114
We created a modular system to build track switches for LEGO® Trains.  There are 9 different parts that allow you to create up to 16 different types of switches.  You can find all the details on our Kickstarter page which we just launched.  Make a pledge if you want to support this project and everything we do!

https://www.kickstarter.com/projects/4dbrix/modular-switch-track-system-for-lego-trains


Here are some pictures of our switches:

Continuous curve switch: fits in a perfect circle.

Parallel track switch: you have the option to put the ground throw on the outside so it doesn't block over-sized cars.

Single crossover: create smooth single crossovers with a 8 stud space in between the parallel tracks.

Double crossover: with 4 independent switches allowing you to run the train parallel.

    Looks interesting. The only thing I'm a little concerned about is that the tracks are 3D printed. My understanding is that 3D printing is still not up to the standard of injection moulding, but I may be behind in the latest developments.

    The tracks you see in the pictures are 3D printed.  

    From a functional point of view there is no difference between 3D printed and injection molded train track.  From a visual point of view there is a slight difference.  The 3D printed tracks have small groves between the layers, you can see those from nearby.  But from a few feet way you cannot tell the difference.  

    Well, that's me talking.  If you want to hear what our customers have to say about our 3D printed track for LEGO monorail:

    I was thinking last week I could do with a continuous curve switch... alas I have a 9V system... :)

    Making switches for the 9V system is something else... We looked into conductive 3D printing filaments but none are conductive enough to power a LEGO train.  But it's a domain that is evolving fast so how knows...

    As a thought, would it be possible to add some conductive tape to the crossover section (with possibly some spot soldering for a feeder wire) make a 'straight' track 9V compatible?

    I'm not sure how easy it is to tape curved sections but I have seen people do it with the LEGO 7996. I also don't have any idea how durable that approach is, i.e. does the tape stay in place or does it come lose at some point.  Do you have experience with conductive tape on LEGO track ?

    We just added new segments to our Kickstarter project to build rail yards.  For more info:
