Our Modular Switch Track System is waiting for you on Kickstarter!
We have developed a complete system of 9 different track parts which allow you to make 16 track switch types for LEGO® trains. You can operate the switches manually with ground throws or automate them with our track switch motors and nControl. Help making this project a success by pledging on Kickstarter and sharing with your friends and LUGs - we also have early bird rewards at a special price!
