There are 3 tutorials that are not categorized, even if they fit any of the other definitions:
About Trains...

Trains are vehicles automatically running on their track. They connect distinct locations, providing convenient access to faraway areas.

Trains show information to players by having an external display of the line number, and texts shown on the HUD upon hovering over the train.

Trains often come with several wagons; each wagon can hold up a few passengers.


Only trains with opened doors allow players to go on board. To board a train, walk inside a wagon with opened doors.

To leave a train, wait for the door to open, then try to walk inside the train. You will be teleported out of the train, and onto the platform, if any.

Alternatively, right-click (tap on mobile) the train to board or exit the train.


Inside the train, texts may be displayed at the bottom showing the next station name. Get ready to leave the train once your destination shows up.

Once the train is at a certain station, its name is displayed similarly.


Under no circumstances should you stay or walk on train tracks. Getting hit by a running train is fatal! Get onto a train, let it bring you to your destination, sit back, and relax.

For the same reasons, you should never attempt to get off the train mid-journey. If you are in an emergency, hold down sneak (shift on computers) when you right-click.
Locking Chests

Storing items in normal chests is dangerous. Other players may take your items from your chest.

To prevent this, use locked chests instead of the normal ones. Craft them by putting the chest and a steel ingot into the crafting grid.
Using the Elevator...

Elevators transport players vertically. To use an elevator, walk inside an elevator and right-click it.


After right-clicking, select a destination from the list of locations. The number left of the name is the Y-axis coordinate of the destination.


To set up elevators, place down elevators so they are vertically aligned. Then, place shafts to fill in any gaps between elevators. Finally, place down a motor on top of the uppermost elevator.
