||Maintaining a common color across the first few inches of the module ends helps to visually integrate the segments in their many configurations. This could be as simple as using poplar, ash, or maple and leaving unpainted. Several sources recommend that flat paint should be used if painting surfaces (ends) that will be clamped to prevent them from sticking together, but a satin or gloss finish is easier to clean and more resistant to marks for the top surface of the table. Eggshell might be a good compromise.
Use 4" tracks to join raised sections (assuming a 1" leg support inserted) and 3" tracks when butted together on the floor.
Images & Textures
Custom images can be attached to Bridges, buildings, rolling stock, and other features for increased realism. Fabric trees and carpeted fields also add texture and depth.
Trees, people, and animals are generally larger than the trains for most manufacturers, but the apparent scale for wooden buildings and trains is roughly 1:87.
Custom Locomotives and Cars
In addition to modifying store-bought trains, custom engines and cars can be constructed.
