A common "cheat" is to only add detailed 3D scenery within the visible range of the cab or trackside cameras. For areas further away, builders rely on a technique where only the ground textures are painted, with no 3D trees or buildings. This creates the illusion of a fully realized world without the performance penalty.

To run multiple trains without collisions, you need a signaling system.

A Trainz map is the stage; a is the play. To get the most out of your map, you must learn Session Rules .

: This is the physical world. It includes the topology of the terrain (mountains, valleys, plains), the track layout, and all stationary scenery such as buildings, vegetation, and roads.
