I searched around the forums a bit and didn't see this posted elsewhere before- I came across these MOCs by Malte Dorowski and though that both the final product as well as the techniques that went into creating them were great so I thought I'd share them here. In particular I had never seen the flex tube -> clip plates -> cheese slopes technique following the curves of the cars, and it looks mighty nice!
Check them out - awesome work by Malte!

(I've seen other's work highlighted by a 3rd party here before, but if this is inappropriate I apologize.)
