Model trees add an extra scenic dimension to any model railroad. They aesthetically enhance landscapes with their colour and texture, helping scenery to appear more well balanced and natural. I would personally recommend to all model railroaders to apply this type of terrain to their models in order to get the fullest level of visual pleasure.
Below I have compiled some of my favourite videos, along with a few of my own, demonstrating how to design your own model trees. Each video provides you with all the tools and steps necessary to create this type of landscape, each demonstrating a different method.
