>>5254030it's actually only 440 pieces altogether, and doesn't use any jumpers at all. The four track pieces all share the same build and just attach at the two ends while the rest of the curves just sit on tiles.
As for the extra plate height I got a bunch of 4x4 green plates a while ago at a PaB wall and decided I wanted modular track tiles and whatnot. I also decided to make a road system that used those 8x16 dark gray tile pieces that no one can seem to use to go with my modulars, but I don't have pics of that on me right now.
