An activator rail is a type of rail that can "activate" certain minecarts.

Obtaining[edit]

Activator rails can be crafted and previously-placed activator rails can be broken with bare hands or any tool, dropping themselves as items.

Breaking[edit]

An activator rail can be broken with any tool, dropping itself as an item, but a pickaxe is fastest. To break an activator rail, mine it:

Block Activator Rail
Hardness 0.7
Tool
Breaking time[note 1]
Hand 1.05
Wooden 0.55
Stone 0.3
Iron 0.2
Diamond 0.15
Golden 0.1
  1. Times are for unenchanted tools in seconds. For more information, see Haste § Instant mining.

An activator rail also drops as an item when the block beneath it is removed, water or lava flows over it,‌[Java Edition only] or a piston moves it into a space with no floor below it.

Crafting[edit]

Chest loot[edit]

Activator rails can be found in 27.1% of chest minecarts in Mineshafts in stacks of 1–4.

Usage[edit]

Placement[edit]

An activator rail can be used as a rail and as a redstone component.

To place an activator rail, use an activator rail item while pointing at a surface facing the space the activator rail should occupy. An activator rail can be placed on:

An activator rail cannot be attached to the side or bottom of any block, but attempting to make such an attachment may cause the activator rail to attach to the top of a block under the destination space. For example, if a fence is on the ground, attempting to attach an activator rail to the side of the fence causes the activator rail to be attached to the top of the ground next to the fence instead.

When placed, an activator rail configures itself to line up with any adjacent rails (including detector rails, powered rails, and other activator rails), as well as adjacent rails one block up. If there are two adjacent rails on non-opposite sides, or three or more adjacent rails, an activator rail aligns itself in the east-west direction. If there are no adjacent rails, an activator rail aligns itself in the north-south direction (but if a rail is later placed to the east or west, the activator rail re-orients itself in the east-west direction even if it is already connected to another rail to the north or south). If a rail it would align with is one block up, an activator rail slants upward toward it (with multiple options to slant upward to, an activator rail "prefers", in order: west, east, south, and north). Other configurations can be created by placing and removing various rails.

Rail[edit]

Activator rails (and other rails) can be used as "roads" for minecarts. A minecart that enters an activator rail's space from either end of the activator rail continues to move, losing only a little velocity (which can then be increased again with powered rails). A minecart that enters an activator rail's space from the side turns east or south (depending on the activator rail's orientation), or in the downward direction for a slanted activator rail.

Redstone component[edit]

Activator rails can be used to affect minecarts that travel over them.

Activation
An activator rail is a redstone mechanism and can be activated by:
An activated activator rail also activates any adjacent activator rails it is connected to, up to eight away from the original activation source. Thus a single activation source can activate up to 17 rails (one original in the middle and eight on either side). An activated activator rail does not activate adjacent rails not connected to it.
Behavior

An activator rail affects minecarts above it with varying effects that occur as soon as any part of the minecart is on the activator rail.

An active activator rail:

  • ejects mobs (including players) from minecarts as if a player had used the sneak control to exit the minecart (by default, one block to the right of the direction the minecart is moving and up to two blocks up, unless blocked)
  • repeatedly activates command block minecarts — a command block minecart executes its command every four game ticks until the command block minecart is no longer on the activator rail
  • disables hopper minecarts — a disabled hopper minecart cannot pick up items it travels through until it is enabled by an inactive activator rail (or until it is broken and re-placed)
  • primes TNT minecarts — primed TNT minecarts explode after four seconds with an explosive power proportional to their speed over the activator rail.

An inactive activator rail enables hopper minecarts — an enabled hopper minecart picks up items it travels through until it is disabled by an active activator rail.

Data values[edit]

Block data[edit]

In Bedrock Edition, an activator rail's block data stores its orientation and activation status:

Bits Values
0x1
0x2
0x4

A three-bit field storing a value from 0 to 5:

  • 0: flat track going north-south
  • 1: flat track going west-east
  • 2: sloped track ascending to the east
  • 3: sloped track ascending to the west
  • 4: sloped track ascending to the north
  • 5: sloped track ascending to the south
0x8 Set if rail is active.

Block states[edit]

Java Edition:

Name Default value Allowed values Description
poweredfalsefalse

True if rail is activated.
shapenorth_southeast_west

1.915w39aDismounting location is now predictable. Entities dismount from vehicle (boats, minecarts, horses) by the right side relative to the motion of the vehicle. If the right side is unavailable, the other potential locations are tested in this order : Right, Left, Back Right, Back Left, Front Right, Front Left, Back, Front.
