It is the world of Minecraft and this is a map of the world. You are free to do whatever you want in this map. You can go to the mountains, the desert, the oceans, the caves, the villages, the cities, etc. You can even go inside the Earth or the moon.

You will be able to drive a train, which will allow you to travel from one place to another. Your train will have different vehicles, which will let you go to different places. The vehicles will have different speeds and functions. You will have to train the vehicles so they can work properly. 

You can even drive the train from the world map. This will be very convenient for you, as you will not have to go through the game map.
