Building Curve with Train Tracks

Let’s expend upon the previous post. Curved train tracks are not only good for making circles. They make great curves too, duh. We first start with a curved train track. Then we expend it out on both sides of the track. It’s best to do it on both sides equally for reasons below. When the gap is too large,  we can use the half-plate offset technique that we talked about in the last post to minimize the gap. You can adjust the width of the curve to your need. I picked 6 studs in this example. This is our “curve unit”.

By connecting our “curve unit” in different directions we can create different curvy shapes. We can even throw in a few straight train tracks. If you expended the track on both side equally it’ll flow smoothly when you alter the direction.

For example in this moc, there are 4 layers of train tracks. One for the base, one for the ceiling, and two extra layers in the middle. This moc is as sturdy as a single brick, after reinforcing it with tons of bricks. 😉

You can also connect two curves back to back to create a curved beam. I have not used this structure myself, but I can imagine using it as a curved gate or some animal’s neck. As with all things lego, the only limit is your creativity.

The train curve is a very interesting piece. I really wish to see it been used more often. The techniques that I’ve shared are not the only uses for them. I don’t intend this blog to be a place for step by step instructions. I hope this blog could be an inspiration for my readers to come up with more interesting techniques yourselves.
