Creating a train for MTR using BBMODEL
This guide will help individuals without experience of creating trains for MTR mod a basic knowledge of how to create them and what they have to be aware of when creating it.
This guide is intended for MTR3, not MTR4. While the process of crafting the train in Blockbench will remain mostly the same, configuring it will show difference due to the new train rendering system that will be introduced in MTR4.
Before you start
Before you start, make sure that you have the following items are in place.
1. Blockbench
- This is where you will create your model.
2. Photo Editor
- This is required to make the texture for the model.
You may also want to have these in place to assist you on creating the model.
1. Sufficient reference images.
2. Models from the core mod.
Creating the model on Blockbench
First, open Blockbench. In the “New” tab, select “Modded Entity”.
Ensure that you're choosing Modded Entity, not other types of models, else your model won't work.
Then you should come across to this dialogue box. Simply assign a meaningful name in File Name: and press Confirm.
Creating model parts
Now, let's create a group. A group is used to identify a “part” when we move to the resource pack creator later. Click the “Create Group” button to careate one. Alternatively, press Ctrl + G will also do the trick.
It is important that all cubes are within a group, and all groups have at least one cube, regardless of the size. If not, the game will crash.
With a group selected, let's create a cube. The button is next to the Create Group button. Alternatively, press Ctrl + N will also do the trick. You will then see a 2x2x2 cube appearing in the working area. 
Bodyframe
Before you do anything else, you're advised to firstly create a bodyshell. You will need a reference image if you're creating a real-world train. In this case, I am going to use this image.
