"trainz-build" number

New releases of Trainz bring new features and improved content validation techniques. This will happen for major product editions (eg. TS2010, TS12 and TANE) but may also occur during the larger service packs which are released for each product. The "Trainz-build" number is used to differentiate these compatibility versions, and the corresponding "Trainz-build" tag is used in each asset's Config.txt file to specify the minimum Trainz version required in order to use the asset.

Trainz-Build version numbers and their mapping to official Trainz release versions are as follows:

Obsolete Versions

The Trainz Life-Cycle Policy defines which product releases have active support from N3V Games. While users may continue to use older products, including downloading such older content from the Download Station and even creating new content for these older versions, it is typically not possible to upload content with an unsupported "Trainz-build" number to the Download Station. This ensures that older content-creation techniques are slowly phased out over time in favour of the more recent improvements.
