The Download Station is N3V Game's public repository of 3rd-party custom Trainz assets, and was instituted in the Trainz 1.3—Trainz UTC (versions 1.3–1.5) era of early Trainz releases during which it's library of assets swelled from a few hundred assets well into the thousands. Any Trainz user may upload their home-built content and download content made by others using the facility, which in recent years has been belatedly changed to vett uploaded content in an attempt to weed out assets made to older technology standards, ensure only legal tag names (key words) and newer data types and data structures are incorporated, and an asset is complete as well as has all dependencies on the DLS. Early in the TS2009 era, the DLS instituted a policy of only accepting content made to or upgraded to currently supported releases of the software, concurrent with a policy implemented to limit their customer support to such supported versions.
Content on the Download Station has historically shown significant rates of errors or missing dependencies. This is being addressed via the Download Station Cleanup.
