While little-to-no information is known about this version of Trainz, it originally started life as a set of downloadable files in 2000. It was renamed under the name of Content Manager Plus (CMP) in TRS2006.
The Content Manager (CM) module is a Windows program that allows management of the in-game database files. PaintShed is a simple program for aiding and easing the process of 'reskinning' traincars, altering their livery, by recoloring and adding new heraldry to Trainz locomotives and other rolling stock.
The simulators are supported by a large library of freeware assets which can be downloaded from the N3V servers, referred to as Download Station (DLS). Screenshot of TS12 or Trainz Simulator 12 in driver mode showing an Amtrak HHP-8 at 30th Street Station Other software
