Track Relayer Cart

The Track Relayer Cart is a special type of Minecart from the Railcraft mod. This cart is used to replace the Tracks that it is riding on, without the need to manually break them. When linked to a Chest Cart using a Crowbar, the tracks it breaks will go into the Chest, and it will use the Chest as it's stock for tracks to place. Without the use of a Chest Cart, the tracks it breaks will fall onto the ground.

Usage
The Track Relayer Cart GUI has 2 sections, Pattern and Stock. Pattern is used to define what to replace and what with. In the first slot place a ghost block of the track you wish to replace, and in the second slot place a ghost block of the track you wish to place down. Stock is where you will store the tracks you are replacing.
