This is a moving command block train.

It moves, and you move with it when in it or on it.

HOW TO USE:

Firstly, you need to spawn the train. To use spawn it you need a book named "Train Controls". It should be already in your inventory as soon you will enter the world. Then press the text saying "Spawn Train". Now a train should appear on the tracks. Now you can pilot it using the same book. Press the green texts in the book and the train will move. The one says "forward, west" will make the train move in the side with the glow item frames on the locomotive and one saying "backward, east" will make the train move in the side with the normal item frames on the locomotive. To stop it just press the red text saying "Stop Train". And to remove the train just press the text saying "Destroy Train" and this will remove the train and you can now spawn a train again.
