Not every map made for this game needs to be realistic. As long as it's fun for you, make what makes you happy. In the video above, I show the process of not only building the track layout in minecraft, but also how to actually do this yourself and make something even better than what I have here.
Have fun with it.
Track requires:
LightingFX
Tools used:
RTB
