Description:

Placeable Rail Trench Block: a diamond-textured block with a powered-rail icon on each face that, when placed, cuts a one-block-deep straight trench 20 blocks long in front of the player, fills the trench floor with redstone blocks, and places a powered rail above each redstone block oriented along the trench. To use it, aim where you want the line to go and place the block—the trench will always extend outward from your facing direction and will dig down one block before laying the redstone base and rails.
