Petrol and Oil sands

Overview
The diesels locomotives need diesel to run, diesel is created by distilling oil sands or crude oil in a  distillation tower.

Theses ores can be found: - between layers: 64 +/- 6 for Oil sands, spawns only under top layers of sand - between layers: 44 +/- 8 for Petroleum

The ores are set to spawn with the default setting, but if one wants to prevent them from spawning, the option ENABLE_ORE_SPAWN in the "Traincraft.cfg" file in the "config" has to be set to false. You don't need to generate a new world, just go somewhere you have NEVER been. As the generation works will newly discovered chunks. Below is a picture of both ores. Oil sands(right) also acts as a falling block e.g. sand or gravel.
