A railway-specific foundation tile that can be placed on Fulgora's oil oceans. You can build non-elevated rails but need to bring the tungsten over.

Date: 2026-07-16
Balancing:

Version: 1.1.3
Date: 2025-05-06
Changes:
- Oil ocean now longer has a default cover tile. Removed the cover tile workaround setting. (This results in oil ocean having same effect as Aquilo ice platforms, where Factorio will use the tile you last placed as the cover tile.)

Changes:
- Stack size increased from 50 to 100.
Version: 1.1.1
Date: 2025-05-05

Date: 2025-05-05
Features:
- New icon for rail foundation.
- Added a startup setting to choose which foundation tile is used to cover the oil ocean.
