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.
