For designing the actual train track, let me first design the path. So I'm going to say create sketch and choosing this plane. I'm going to display an option and first drawing the path of the track. Now I'm going to stop sketch, I need a plane, which is perpendicular to this path. So I'm going to construct plane along path. So I'm selecting this plane.

Now you can see I can move this plane I wanted at the end point. On this plane, I'm going to create my profile. So here I can draw the eye section. In the same way, I had drawn in the previous section. I'm like no not using the mirror tool. I'm going to use some constraints.

Now I'm ready to sweep. So here I can go to create and sweep option. This is my profile. And this is my path. So it is now going to sweep along this profile that is this cross section is going to be swept along this curve. So I'm clicking OK. Now I can make my changes to this path.

I can either right click and say Edit sketch or do it dynamically over here. I'm just making it visible because I want to do it dynamically. So you can see here, how my path changes. So this is not possible. So it is showing the one I can even add Some points on them. And then I'll turn it so you can see I have created the train track using this option.
