Coming Soon: A description of the different major roads, rails and other means of organized transporation that lead between regions.
Before the regen of outer regions in 2014, most official/major roads (particularly north/south/east/west) extended fully between the towns at the center of each region.
There used to be a well designed railway system in use on the Overworld. There were 9 coloured railway lines that connected each region's capital city at their railway stations. A player would visit the station and with the simple press of a button, could summon a minecart train that would automatically stop at each station for a few seconds before moving on again. Using command blocks, if a minecart train reached a certain point without a passenger, it would automatically disappear thus keeping the use of memory and the lag to a minimum.
Some of the old railways can still be found in the wild, but are not currently in use as they once were.
