If you have the correct TRS22 build installed and you have purchased TRS22PE, then the game should automatically update to the TRS22PE branding and unlock the features in-game once you login with your MyTrainz account. The build number information is listed on the Trainz Trainz Wiki. Next, you can check to see if you have a compatible TRS22 build installed that enables the Platinum Edition features. First, you must have purchased Platinum Edition so our backend can give you access to all the Platinum Edition features.
