Train Sim World 5: How to Bring Owned Steam Add-ons into the Game

Check that the older add-on has a TSW 5 version

TSW 5 supports many earlier add-ons, rather than promising compatibility for every product ever released. Use Dovetail’s Add-On Compatibility Guide, linked from the FAQ, to identify whether the particular add-on has a compatible version. [1]

Start with this compatibility check before treating an absent route or locomotive as a failed download. The FAQ distinguishes route and locomotive products, and notes that a loco add-on normally requires an associated route. [1]

Check the locomotive product’s route requirement as well as the game-version compatibility. [1]

Use the same Steam platform and account

Use the Steam account that owns the older add-on and TSW 5. The publisher’s entitlement condition requires both the same platform and the same account. An Epic purchase on the same computer is a separate platform purchase. [1]

Dovetail’s platform list separates Steam on PC from Epic Games Store on PC. [1]

Download the TSW 5 files for each compatible add-on

Download the TSW 5 version of the compatible add-on, even if the earlier game and its add-on are already installed. The games do not share those files. The older installation can coexist, but it does not supply the new game’s add-on installation. [1]

Steps

1. Download the Train Sim World 5 version of each compatible add-on you want to use. [1]
2. For add-ons bought in a bundle, download the bundle’s individual components. [1]

Import progress separately from content ownership

Profile progress and platform purchases have different roles. The FAQ says the profile and Dovetail Live do not record purchase entitlements, so importing a profile does not replace the download task. [1]

When checking missing content, verify the owned add-on’s TSW 5 files rather than repeating profile import as though it transfers store ownership. [1]

Do not depend on claiming the expired Starter Pack offer

The FAQ now explicitly marks the Free Starter Pack promotion as ended. Its historical instructions for claiming that promotion should not be read as a currently available free upgrade. Use the TSW 5 licence already held on the correct account, or its available paid offering, when applying the compatibility instructions. [1]
