detection rail is an object which can transport Mine Trolleys and can be used as a switchable Scarlet Rock power source.


A detection rail can be obtained by crafting, or by breaking a previously-placed detection rail.


To remove a detection rail, mine it. Detection rails can be broken fairly easily by hand, but can be broken quicker by using a Pickaxe.

A detection rail will also be removed and drop itself as an item:

  • if its attachment is moved, removed, or destroyed.
  • if water flows into the detection rail's space.

If lava flows into a detection rail's space, the detection rail will be destroyed without dropping itself as an item.


Crafting a Detection Rail takes six Metallic Ingots, one Scarlet Rock, and one 1500-Megawatt-Scarlet-Rock-Super-Colliding Super Button.
