After having seen many videos about redstone on youtube (merci Zephirr!), I have decided to create a redstone industrial world with a lot of mechanics.
In this map, you can find:
- a Town with its Station.
- a Steel Factory with an Unloading System for the Ores and the Coal, a Sorting System, Quick  Furnaces to make steel or gold lingots and Shipping System.
- a Harbour with an access to the River and an Unloading and Shipping System.
All these facilities are connected by a sophisticated Railway System, composed of:
- Several Tracks.
- a Station with four platforms.
- two Switches.
- a Level Crossing.
- a Railway Crossing.
- and a Bridge.
You can travel between the different facilities or ship freight (ores, coal,lingots) from the station to the steel factory and then to the Harbour. For this put a transport minecart on the right platform, fill it with ores and coal, put the switch in the good position and launch it.

This map is for beginners in redstone.
