You know, that i make many stuffs about create mod trains. And here is how i make them when not showing on a YouTube video.

Creation of Trains

1) Train Tracks & Stations: Place down train tracks, they are 3 blocks wide like in Immersive Railroading or RTM. After placement of tracks place a train station block from the create mod by right-clicking any straight train track. Then place it nearby, it will after say "Successfully bound to train track". Then in the Station's GUI press the button with a + icon and a steam locomotive. Place bogeys by pressing blue train tracks with a train casing.

2) Train Bogeys: Bogeys of the train are the main part of a train. In real life they are called Bogies.

3) Train Body/Hull: The hull is a structure of a train placed on top of Bogeys. Make a train hull by building a train construction on top of the bogeys, with the bottom-most layer of your train being placed on the level of bogeys. I recommend building the train hull being a Steam locomotive.

4) Assembly: Now you should super glue your train build, if your locomotive exceeds the 2 bogey limit, then glue the parts with 2 bogeys. So for example i have a 4 bogey locomotive and just i have to glue the front part without the cab with 2 bogeys and the other part with 2 bogeys with the cab as a second carriage. So if it also has a tender then the train will be as 3 carriages. Now press the button "Assemble Train" in the train station's GUI, then it should turn your train into a contraption. Done!

Conversion of Railway maps for other train mods/vanilla to Create

1) I replace the train tracks of other train mods with create mod train tracks. But if vanilla i remove the side sleepers and then replace the train tracks with gravel. Then i place the train tracks.

Note: i also sometimes might upload IR maps
