Custom Arrow Model Coaster

This is my second attempt at creating a custom arrow model coaster. The grey tack ties used for the model are 3d printed, but apart from that, everything is handmade mostly from 1/8" craft board, polyethylene tubing, plexiglass, and many other materials. Attached are various progress photos as I go from creating a functional layout to a more realistic looking coaster with aesthetic supports, trains, etc. Enjoy!
