Major update

TRS22 - Service Pack 1

Trainz Railroad Simulator 2022 · published 4 years ago · build 9709968

All eventsPlayers around this dateRead on Steam

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:

  1. Custom Content Package support*
  2. TZARC compression - 50% reduction in file size
  3. Update to Trainzbuild 5.2
  4. Improved audio - XAudio2 sound system API update for PC
  5. End of official support for Windows 7
  6. A range of other tweaks and bug fixes


* Note: Configuration 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 route.

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.

Full details about Content Packages can be found in this wiki link.

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.
