Railway Signal with Rotating Sign


Extend your train universe with this little railway signal!

The design: It has a red and green plate mounted on a turnable head, which you can twist by using the knob at the back.

The inside: As you can see in the last image, there are simply two gears shifting the torque by 90 degrees and rotating the head via a connected bar.

Have fun and keep buidling ;-)
