You may already know this, but this is the first steam locomotive to ever come onto this site! I hope this isn't the only train uploaded to this site that isn't a subway and that the community here keeps growing!
[UPDATE] Added a tender to go behind it
Use the editor window above to rotate or move the model as you want, and then click the
Get the command button to get a new command.
If you want to make more changes or completely remake the model, open the full version
of the editor using the Open in BDEngine button.
To use a command in the game, you need a Command Block, as the chat field in Minecraft has a character limit.
Now you can destroy the Command Block and enjoy the installed model. Repeat the procedure several times if there are multiple model commands in the export window.
Be sure to install Axiom [modrinth] if you haven't already.
