New roller coaster parts

[Jaco van der Molen]

Finally, here are the draft parts of the looping and the raising curve.

Not, I do not have these parts, I built the model digitally and tried to fit the parts accordingly.

So adivce and comments are appreciated, so that I will finish them

Thanks. I have done some adjustments to the model so I can fit the missing tracks.
I look forward to seeing them complete.
