I posted the scenario on the Workshop. I inadvertently used the "wrong" Academy repaint BR189s. I have removed the scenario to avoid confusion, but will re-submit it very soon with the correct BR189s as referenced in the "requirements". I am very sorry for any confusion caused.
On the installation of the BR189 Academy Repaint pack, I just followed the author's instructions:
"Installation
You need to have Academy
installed (Railworks\Assets\DTG\Academy\AcademyAssets.ap). It's a
default component of the game so you got it (except if you have removed
by your self).
Exctract the BR189AcademyRepaintPack.7z file and copy BR189AcademyRepaintPack.ap in the folder Railworks\Assets\DTG\Academy.
Enjoy!
To use the engines in scenarios, check Academy in DTG Rolling stock."
I had no problems whatsoever i.e. the Academy logos did NOT show. However I had already fully extracted the AcadenyAssets .ap file BEFORE adding the repaint .ap file to my installation.
I hope this helps ?
