Just wanted some city blocks that required slightly less foundation on the 3 planets related, so I threw together a raised 1x1 block, a siding, and a 4 Station 4-Car Loop
The siding and block have the specific advantage on Aquilo of allowing you to run heating pipes more easily between things. That specific advantage is missing from the loop, but I might build some later.
Next up will be segments to move between the grounded and raised systems.
