- Creat a consist
- Click on the consist button in top left menu - looks like front of train on paper
- There will be little grey boxes on your consist
- Left click on a box
- Give your consist a name (I use BMc ...)
- Left click anyway on editor window. Your consist will now be saved.
- Right click anyway on editor window to de-select the consists tool. The grey boxes will disappear.
Repeat for other custom consists.
