    Trainz Plus Update / TRS22 SP1 Released

    The latest feature update for Trainz Plus users is now
    available. This release also delivers a "Service Pack 1" update for
    TRS22 users to maintain compatibility for routes and content between
    TRS22 and Trainz Plus builds.

    The latest update includes the following highlights:

    • Custom Content Package support*

    • TZARC compression - 50% reduction in file size

    • Update to Trainzbuild 5.2

    • Improved audio - XAudio2 sound system API update for PC

    • End of official support for Windows 7

    • A range of other tweaks and bug fixes

    * Note: Requires Surveyor 2.0 / Trainz Plus.

    Content Package Palette

    The new Content Package palette now available in Surveyor 2.0
    provides the ability to enable and disable various content packages
    for use in a route.

    This system is required to enable additional content for MPS
    routes. It will also greatly benefit all route builders by identifying
    which packages are being used in your own routes, and those which you
    plan on sharing or uploading to the DLS.

    This means that Trainz Plus members can now enable any existing DLC
    packages for use in their MPS routes, and other users will then be
    prompted to install the required packages prior to entering the

    Custom Content Packages

    It is also possible to create your own custom packages through the
    Trainz Content Creation Program.

    As this is a new system, we’re looking for a couple of teams
    interested in working closely with our content team to iron out any
    kinks in the process. Just submit your package through TCCP and let us
    know in the comments you're interested in MPS.

    TZARC Compression

    All users (TRS22 and Trainz Plus) will benefit from this feature
    which reduces the size of .tzarc files by roughly 50%.

    There are three main benefits to TZARC compression:

    • Faster downloads (twice the speed since DLC packages are half the size)

    • Lower on-disk footprint (including for the built-in content)

    • Potentially faster loading, especially on slower drives (depends on your hardware)

    Note that your existing installed content is not automatically
    reduced in size. It requires either a resave for modified content or a
    new package downloaded for DLC items.

    Improved Audio

    This is a back-end update that brings support for the latest
    Microsoft sound API to PC users. This resolves a rare but
    long-standing bug in the OpenAL API (where Trainz would crash when you
    reached 63mph) and delivers improved sound across the board.

    Please note that there are no other changes to the internal sound
    system. That project is a major undertaking and will be addressed when
    we find more time in our schedule.

    End of Windows 7 Support

    XAudio2 ships with Windows 10 and as a redistributable for older
    Windows versions. As Microsoft updates their API, it is likely that
    Win 7 initially, and then Win 8 will no longer be supported.

    We are announcing the end of official support for Trainz for any
    Win 7 users (which ended official support with Microsoft in January
    2020). You will need to either remain on your current build, or update
    your operating system to use any future Trainz updates.

    If you need to go back to a supported build, we have archived the
    Win 7 supported builds here.

    Also as a side note, Microsoft also ends Win 8 official support in
    January 2023.

    Bug Fixes

    As we work to continually add features and improve Trainz, we also
    work on fixing as many bugs as possible.

    The key to resolving any outstanding issues is finding a reliable
    way to reproduce the issue.

    If you have an issue that has not been addressed, then please
    submit a detailed report through our online bug reporting form.
