Since you are on Trainz+, you want to update that to 117649 which is the latest build besides this is TRS22 with Surveyor 2.0 To update this, ensure you are on the Trainz-Plus update stream and not the Trainz-Plus beta stream. Now, if you're already updated Trainz+ and build 117649, there's no need update because the RC version became the full version automatically with no change.
If you update your TRS22, you'll break your Trainz+ by removing those features from your account.
Confused? You're not the only one!
Read through Tony's first post that will hopefully 'splain this a lot better than I did.
