Video is for setting up the cobble generator if it isn't already active. Nugget farm i used: https://createmod.com/schematics/iron-farm-3.

Fully automated train track farm. To start it, disable the clutch near the decorative flowers. Then go through the setup process of the massive generator if it isn't already set up. Now, feed the steam engine with anything flammable and some water buckets. Finally, start the tree farm by opening the glass trapdoor and right-click the bearing. It should start working if everything is set up correctly.
NOT designed for survival. Could be used in survival, sure, but it's pretty pointlessly expensive.

Final note, press the button in the corner next to the train track chest to activate the fake pressure release valve. It whistles after 30 seconds.
