Experimental chunk loading

Experimental Chunk Loading is an optional feature introduced in the Urban Update. It allows trains to continue running even after they leave player-loaded areas, making true automated rail networks possible for the first time in TRAINS. This was one of the most requested features from players, since trains previously stopped the moment they exited the player’s current chunk, preventing any form of long-distance automation.

Functionality

The feature is disabled by default and must be enabled in settings before it can be used. Each engine must then individually enable chunk loading in its own control menu. When active, an engine keeps the chunks ahead of it loaded so it can continue moving without a player nearby. Because the system is experimental, it may introduce world lag or performance issues on some devices.

Interaction

Players enable the feature globally through settings, then toggle chunk loading per engine. Once active, trains such as subway locomotives, drilling engines, and other long-range setups are able to operate independently and travel great distances. This makes the feature especially useful for automated metro lines, drilling tunnels far away from the player, and large-scale city rail networks.
