Computer Interlocking with ComputerCraft and Railcraft

Hello!

I developed a computer interlocking system for CompterCraft, which incorporates Railcraft to control signals and switches, and to connect them together using Signal (Relay|Controller) Boxes. The whole code was written in ComputerCraft and is usable without Railcraft.

The system consists of multiple small programs, which have a few jobs:

• The Controller controls all signals, switches and running lines. It also includes a router using Dijkstra's algorithm.
• The Interface displays the running lines, signal aspects and switch states, and is the main interface for the user
• Switches, signals and detectors have their own small programs, which can hold a lock and set/receive their states

Configuration is a little bit tricky, because you have to define a Graph of your railway system, and then you have to create a screen for your Interface. You can see a sample controller/interface configuration there: http://paste42.de/7302/

The configuration files for the other components are rather simple and generic due to many abstractions.

Important missing features are Velocity measurements and automatic block signaling.

could you make a video describing the system and how to set it up?
