    Building

    • Airport hangars can now be built in the specific cases where that failed.
    • Stops on modded asymmetric streets get the right terminals.
    • Airport fences no longer flicker, and tram depot doors open properly.

    Map editor

    • The Keep Heightmap option works, and the construction menu buttons sit where they should.

How updates arrive

Steam, the Epic Games launcher and GOG Galaxy download new versions by themselves. Without GOG Galaxy, download the latest build from your GOG library. Consoles install updates on their own at the next chance. Every major update is announced on the official website and on Steam.

Try the preview branch on Steam

Upcoming fixes often reach Steam's preview branch before the main version. To switch:

  1. Close the game.
  2. In your Steam Library, right-click Transport Fever 3 and choose Properties.
  3. Under Game Versions & Betas, pick preview from the list.
  • You can switch back at any time.
  • The preview build is always the same as the main build or newer.
  • It may be less stable, so save under a new name before you play on it.
  • A save made in a newer preview build may not load in an older release.
  • Some mods can break after an update until their authors catch up.

How we keep this page current

We read the official release notes and Steam announcements and add each new version here, rewritten in plain English, with a note on whether it changes the data in our tools and guides. As of October 6, 2026, the newest official announcement on Steam is still the launch post, and the preview fixes so far are listed only in the release notes.

Guides and tools

Our guides are checked against the version listed on each page: Town Growth, Noise and Pollution, Company Ranks, Perks & Prospecting, Why Cargo Won't Unload, Map Sizes and Experimental Maps, and Vehicle Unlock Dates. The production chain planner and Industries and Cargo Types follow the same rule.
