And if you'd like to build your own, I made this handy kit:
Two-way (Fan and ice block) transit system.
Parts link together, there's a gap at end to insert next bp section.
The gap will need filling after building, with 2 bedrock walls and 1 reinforced glass block (not incuded in bp)
...or whichever blocks you use to customise.

The 'Fixed' in the title is because in my first release of this set, the track was made from Ice-Blocks (which melted when built anywhere except an icy biome) and some of the fans needed moving. Big thanks to LightGOC who pointed-out: Ice-Slopes can be used with no fear of melting :)

cool no pun intended and yes I would love to build one, I love the looks of it.
