Rail Post
The Rail Post is a railway item in Astroneer. It allows for the creation of rail lines and can be used to recall Rail Engines to it. It can also be used to channel power and oxygen between bases.

Uses
Placing a Rail Post within range of another will connect a rail line between them, deforming any terrain that might be in the way.
Rail Posts may be placed on any terrain, allowing for placement on walls and ceilings of caves.
The maximum placement distance for the post is shown as a colored dial on the base of the post when placing.
- White indicates valid placement, below the maximum rail length.
- Blue indicates valid placement at optimal rail length.
- Pink indicates invalid placement -- whether from being placed too far, too close, or from creating too sharp of a turn.
In addition to allowing railroad transit, rail lines also function as extension cords to carry power and oxygen over long distances. While somewhat clumsy for this purpose, they are quite inexpensive and densely bundled for the amount of distance that they cover, can split off power and oxygen without needing a special splitter, and can be made with locally available minerals on every planet.
Notes
- Rail Posts are unable to be placed directly into a Shredder. They may only be shredded when bundled.
