GREAT

Welcome to the GREAT Redstone Enabled Automatic Transit (GREAT) system's documentation!

This repository includes information about how our systems work, and how expansions or integration with other systems should be built.

If you're interested in contributing -- either to the docs or to the system itself -- contact WorldWidePixel or Blurry on the CRSS Discord.

Index

Things may get long, so for future-proofing we'll include a chapter index.

  1. The System

1. The System

GREAT is an easily-expansible and resource-efficient railway transit system.

Track tile grid

The track tiles are based on a 9-1-9-1 grid (see the example below).

Cobblestone c
Redstone Torch T

Powered Rail R

Station Stops

Station stops are a little more complicated. We use angled Powered Rails and buttons or redstone signals to make the minecarts stop and accelerate in a convenient way for the passenger.

Turn Tiles

Turn Tiles are a little tricky since they must keep within the grid. They are also a bit more expensive with Powered Rails and Redstone Torches to ensure the minecart doesn't get stuck on them.

The tiles for these are massive, so I separated them each on a code block.

Block Direction Character

Rail West - East -
Curved Rail South - East ¹
Curved Rail South - West ²
Curved Rail North - East ³
Curved Rail North - West ⁴
Powered Rail North - South *
Powered Rail West - East +

¹ = / -     |   ³ =  |
    |       |      - /
