Rail TNT

Six charges, and every one of them stops itself

Corridor TNT cuts up to 256 blocks and decides when the run is done � out of a tunnel into open air, or at the first real hillside rather than boring through it.

The two ramps climb and dive at 1:1 for up to 64 blocks, every rail powered. Up stops once it breaks through; down stops at sea level or when the way ahead changes.

Long Corridor TNT is the one with no stop rule. It runs the full 1024 blocks, so pick your spot.

Wall torches survive the blast

A torch on a wall is lighting: charges drive straight past it and leave it burning. Blast down a mine you have already lit and the tunnel is still lit afterwards.

A torch stood on the ground in the track line stops a charge. Plant your mark where you want the line to end, come back, light the fuse � and the torch is still standing after.

Bedrock stops them too, and both work on the ramps, where the mark is looked for at the height the ramp is climbing or diving to.

Minecarts survive it too

The blast leaves minecarts alone � every kind, chest and hopper carts included, contents and all. Park a loaded cart at the railhead and extend the line straight past it.

They are not shoved off the rails either. Players and mobs still take the blast, so stand back.

Crafting

Everything is built from Corridor TNT � a ring of eight rails around a stick of TNT. Long is four of those in a square; the ramps are three powered rails above or below the charge.

Cleanup is a corridor charge on a sticky piston, Booster is one on a powered rail. Both are inert unless lit on the walkway between two rails.

Also

The two ramps read as up and down in the hotbar � a lit powered rail for the climb, an unlit one for the dive.

The Booster charge powers every rail on track you already have, up to 64 blocks. It digs nothing and lays no new rail, and stops at curves, junctions and detector or activator rails.
