DETECTOR RAIL

A rail that outputs a redstone signal when a minecart passes over it. Comparator can read the contents of container minecarts. Signal lasts while minecart is on the rail.

Crafting Recipe

6 Iron Ingots + 1 Stone Pressure Plate + 1 Redstone Dust → 6 Detector Rails

Signal Behavior

Input

Minecart presence on rail

Output

Signal strength 15 (or container fullness via comparator)

Max Signal Strength

15

Delay

Active while minecart is on rail

Modes

  • Binary detection
  • Analog container reading via comparator

Common Uses

  • Minecart arrival detection
  • Station systems
  • Item transport monitoring
  • Automatic rail switching

Common Mistakes

  • !Signal only while minecart is on the specific rail block
  • !Comparator reads container fullness, not just presence
