This video is how to make the straight rail and the curved rail of my LEGO Monorail.
We can make both rails without special bricks.
I think there are various ways to make a straight rail.
And we can make a both rails in various lengths.
However, when we make long rail, we need to consider about strength.
It is important we can design the layout freely.
Note:
I've changed the color of the parts to make it easier to understand.
